Wiring terminal positions are shown below, along with LED locations.

Connector Locations

Field connections are shown below:

Wiring
Refer to “Connector Locations” and the following images to locate connectors and other components. Descriptions are provided for wiring to ground, to power, RS-485, Ethernet, Inputs, and Outputs.
Wiring Earth Ground & Power

NOTE: Because the MS-E10 Controller uses a half-wave rectified power supply, it should not share a transformer with the JACE-8000, IO-R-34, or any legacy JACE.
NOTE: Use earth grounding to provide protection from electrostatic discharge or other forms of EMI.
NOTE: Pay attention to the following, depending on the type of power source that you use:
AC: Dedicated 24V transformer required, with neither side of the transformer secondary tied to ground.
DC: Polarity is critical to protect the diode (uses onboard half-wave rectified power supply). Connect – to ground and + to the other terminal.
WARNING
Before making power terminations, de-energize the 24V power source.
Do not restore power until completing all other mounting and wiring. See “Power up and Initial Checkout”.

Wiring – continued

Prerequisite: A nearby earth grounding point.

1.  Install the included earth ground wire (1) to the controller’s earth ground spade lug (2), and terminate the other end to a nearby earth ground (3).
2. Unplug the controller’s 2-position power connector (4) and terminate a 24 V supply source (5) to the connector. Leave connector unplugged for now.

RS485 Wiring
On the controller’s top side, a single, non-isolated, RS485 port provides a connection to the IO-R-34 module or to other RS-485 devices (NRIO, BACnet MS/TP, MODBUS). Do not use this port to connect to other controllers.
Use shielded, twisted-pair, 18-22 AWG cabling to wire in a continuous multidrop fashion to other RS485 devices: “minus to minus”, “plus to plus,” and “shield to shield”. 10K bias resistors are permanently connected. There is no built-in termination resistor. The maximum total cable length is 1,000 feet (304.8 meters).
Connect the shield wire to earth ground at the MS-E10 Controller end only. The following image shows example wiring.

1. RS485 port supporting a trunk of RS-485 devices (3 maximum).
   (A) Niagara Supervisor
   (B) Devices
2. RS485 port connected to a single IO-R-34 module.
3. Example wire terminations to IO-R-34 using RS-485.
   (A) Ground at one point on MS-E10 end only.
   (B) Use shielded twisted pair wiring

NOTE: Do not mix an IO-R-34 with other types of RS485 devices on the same RS485 trunk.
NOTE: RS485 devices on the same network should use the same protocol and baud rate. Up to 50 total external points across 3 external devices are supported.

Ethernet Wiring
Two RJ-45 10/100Mb Ethernet connectors are labeled PRI for primary, and SEC for secondary. Use a standard Ethernet patch cable to an Ethernet switch. These ports are suitable for daisy-chaining MS-E10 Controllers (see image below) or for connection to either a JACE-8000 or directly to a network. The maximum distance between nodes (network switch or controller) is 100 meters.
Daisy Chain and Network Device Limits
The maximum number of MS-E10 Controllers that are supported in daisy chain configuration is 16.
IT departments may limit the number of devices or network switches connected to a network port and may disable a port if limits are exceeded. MS-E10 Controllers installed in daisy chain configuration off of a single port count against the limit and may trigger the switch to disable the port. See below for an example Ethernet daisy chain layout.

Using DHCP

Upon the first startup when IP connectivity is detected, the MS-E10 Controller initially requests an IP address via DHCP. If a DHCP address is not found, the controller reverts to a static IP address based on its serial number. The fallback IP address is 192.168.1xx.xx, where xx.xx is the last 4 digits of the serial number. For example, if the serial number is 123456789, the fallback IP address would be 192.168.167.89.
The default subnet mask is 255.255.0.0.
For default platform and station login credentials, see Default Login Credentials.
When MS-E10 controllers are daisy-chained from a JACE-8000, you must configure the JACE-8000 port for DHCP as described in MSNC Startup Guide. Be sure to set up the DHCP server prior to connecting power to the MS-E10 controllers.

Using Rapid Spanning Tree Protocol (RSTP)

By default, MS-E10 Controllers are configured for loop-free daisy chain installations. In some circumstances, it may be desirable to create intentional loops in the physical network to increase fault tolerance of the network. This requires enabling RSTP on all MS-E10 Controllers in the chain. In addition, the controllers must be connected to a network switch that also supports RSTP and has that feature enabled. RSTP allows the MS-E10 Controllers to detect the physical layer loops and disable redundant connections until required (cable unplugged, wire cut, etc).
NOTE: When using RSTP, always communicate with local Network IT personnel for specific guidance.

Types of Input Wiring
Each of the 5 UI inputs supports any of the following:

• Type-3 10K ohm Thermistor (see NOTE, below)
• Resistive 0-100K ohms
• 0–10 Vdc
• 4–20 mA
• Binary Input

Thermistor UI Wiring

The inputs support 10K Thermistor temperature sensors. Input accuracy is in the range of ±1% of span. By default, conversion is for a standard Type 3 thermistor sensor with a sensor range of -10° to 135°F (-23.3° to 57.2°C). Using a conversion type of “Tabular Thermistor,” you can specify a different thermistor response curve by importing a thermistor curve .xml file. The Niagara kitIo module contains an XML folder with thermistor curves for various thermistor temperature sensors. You can also edit and export (for reuse) customized thermistor curve XML files. See the NRIO Driver Guide for details.

1. Use shielded, twisted cable (1) 61m (200 ft) max.
2. Cut and tape back shield wire (2) thermistor (3) end.
3. Connect the other end of shield wire to the ground (4) (for example, use a stud in an enclosure).

Resistive 0-100K ohms UI Wiring
The inputs can read a resistive signal within a range from 0 to 100,000 ohms. Wiring is the same as shown for a Thermistor temperature sensor, above.
NOTE: UI inputs provide optimum resistive-to-temperature resolution in the 10K ohm range.
For a sensor with a range far from 10K ohms (such as a 100-ohm or 1000-ohm sensor), the resolution is so poor as to be unusable! To successfully use such a sensor, install a transmitter that produces a Vdc or mA signal, and then wire the transmitter to the UI according to the 0–10 Vdc or 4–20 mA instructions.
0-10 Vdc UI Wiring
The inputs support self-powered 0–10 Vdc sensors. Input impedance is greater than 5K ohms.
0–10 volt accuracy is ±2% of span, without user calibration.

1. Use shielded, twisted cable (1) 61m (200 ft) max.
2. Cut and tape back shield wire (2) at sensor (3) end.
3. Connect the other end of shield wire to ground (4) (for example, use a stud in an enclosure).

4-20 mA UI Wiring
The inputs support self-powered 4–20 mA sensors. Input accuracy is ±2% of span, without user calibration. Use a 499-ohm resistor wired across the input terminals.
NOTE: When using an externally powered 4–20 mA sensor, be sure to de-energize its power supply before making or changing any wiring connections to the MS-E10 Controller.
This is in addition to removing power from the MS-E10 Controller. DO NOT apply external power to the UI inputs without the 499-ohm resistor in place. Otherwise, even a momentary application of power (for example, 24 Vdc) to the UI terminals without the resistor may damage circuitry on the MS-E10 Controller. Only after completing all input wiring should you restore power to such external power supplies.

1. De-energize the 4-20 mA sensor (3) and remove any power from the MS-E10. See Note, above.
2. Use shielded, twisted cable (1) 61m (200 ft) max.
3. Cut and tape back shield wire (2) at sensor (3) end.
4. Connect the other end of shield wire to ground (4) (for example, use a stud in an enclosure).
5.  Wire the supplied 499 Ohm resistor (5) across input terminals. See Note, above.

Binary Input UI Wiring
The universal inputs support normal dry (equipment status) contacts. Standard dry contacts must have a 1 Hz (or less) COS frequency, with a minimum dwell time > 500 ms (contacts must remain open at least 500 ms and be closed at least 500 ms). Dry contacts support 11 Vdc open circuits or 733 µA short-circuit current.

1. Wire the shielded, twisted cable (1), 61m (200 ft) max, to Binary Input, dry contacts (2).
2. Cut and tape back shield wire (3) at sensor end (2).
3.  Connect the other end of shield wire to the ground (4) (for example, use a stud in an enclosure).

Types of Output Wiring

MS-E10 provides 3 Triac digital outputs and 2 0-10 Vdc analog outputs. Triacs are not powered by the controller.
Binary Triac Output Wiring
NOTE: Triac outputs are suitable for AC only. DC loads and dry contacts require an intermediate relay.
NOTE: Never use a controller’s power transformer to power I/O loads. Using the controller’s transformer introduces potentially damaging switching transients into the unit.

Each digital Triac output (1) is rated at 24 Vac +/- 15%, 50/60Hz, at 0.5 A max. Outputs are normally open, floating, and do not share a common pin.
Analog Output Wiring
Analog outputs (AO) are referenced by the terminals labeled AOn and 0 V. Each AO can supply a maximum of 4 mA over the entire 0 to 10 Vdc range. The minimum input impedance of a device controlled by an AO must be greater than 2500 ohms.
Accuracy of the AO is specified at +/- 2% of full scale, with a max load of 4 mA. If the AO is operated with a load that is within spec, the deviation will be less than 2% of full scale (200 mV) over the specified operating temperature range.

1. Wire the shielded, twisted cable (1), 61m (200 ft) max, to Binary Input, dry contacts (2).
2. Cut and tape back shield wire (3) at sensor end (2).
3. Connect the other end of shield wire to the ground (4) (for example, use a stud in an enclosure).

For analog output, wire 0-10 Vdc device (1) to the controller as follows.

1.  Connect Device Common Ground (2) to 0 V (3).
2. Connect Device Input (4) to the analog output (5).

Power up and Checkout

Refer to the illustration and steps below to apply power and verify the basic operation of the controller.

Power Up and Initial Checkout
3. Apply power by inserting the 2-position 24 V power connector plug (1).
4. Check that the green STAT (2) and yellow BEAT (3) LEDs are flashing, as described below.
Status LED indications
When power is applied, the green “STAT” LED illuminates. This indicates the system is OK, with power applied. During bootup, the “BEAT” LED may blink at 5 Hz with a 50%/50% on/off duty cycle. When bootup completes, the platform daemon is started, and the normal 1 Hz flash at 50%/50% on/ off duty cycle of the “BEAT” LED returns. If the “BEAT” LED stays illuminated constantly, does not illuminate, or blinks very fast, contact System Engineering for technical support.
NOTE: The 5Hz, 50%/50% on/off “BEAT” flash at bootup also occurs during other critical operations, such as a firmware upgrade to the controller.
To be safe, do not remove power from the controller while its “BEAT” LED flashes with a rapid 5Hz rate. Wait for the normal (50%/50%) flash to return before removing power.
For more LED details, refer to Niagara Community Tech Tip article: Edge 10 LEDs: Status and Heartbeat.

Debug Port and Factory Reset
Along the bottom side of the controller is a debug port for serial debug communications and a Factory Reset button. See the MS-E10
Install and Startup Guide for information on setting the controller to factory defaults.
The DEBUG port is a standard Micro-USB AB port for serial debug communications to the controller. Use a serial terminal program (for example PuTTY) to access the controller “system shell” menu. This provides access to some basic platform settings.
Default DEBUG port settings are: 115200, 8, N, 1 (baud rate, data bits, parity, stop bits). For details on using a serial connection to the DEBUG port, see the MS-E10 Install and Startup Guide.

DIN rail mounting is recommended. Where tab mounting is required, use dimensions in the illustration to mount the controller.
NOTE: Do not mount hardware on both a DIN Rail and with tab mounts to another surface. This causes physical stress on equipment.
1 MS-E10 Controller. Allow at least 1.5” (38mm) clearance around all sides.
