Concept
MP-C-36A-M Screw Terminals
The MP-C-36A-M model has 36 I/O points and the controller is equipped with 61 fixed screw terminals and a 3-position removable screw terminal block.
Danger
|
|---|
|
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Disconnect the power supply and other high voltage equipment before wiring. Failure to follow these instructions will result in death or serious injury. |
Recommended screw tightening torque: 0.56 Nm (5 lbf.in)
The 61 fixed screw terminals are used as follows:
Three screw terminals for the power input
16 screw terminals for the eight relay outputs
42 screw terminals for the 28 universal inputs/outputs of type Ub
The 3-position removable screw terminal block is used for connection to the BACnet MS/TP (RS-485) network.

Power input |
|
|
|
1 |
24 VAC/DC |
24 VAC, 50/60 Hz, 12 VA Positive lead (+) when operating the device from 24-30 VDC, 6 W |
|
2 |
|
Earth ground lead of 24 VAC transformer connects to terminals 2 or 3. Terminals 2 and 3 are internally connected. Negative (–) lead when operating the device from 24-30 VDC, 6 W |
|
3 |
|
Terminal 3 is provided for convenience to connect to protective earth ground (optional). Terminals 2 and 3 are internally connected. |
|
RS-485 terminals |
|
|
|
4 |
RS-485+ |
Connection to TX/RX+ (RS-485+) signal in the BACnet MS/TP (RS-485) network. |
|
5 |
RS-485– |
Connection to TX/RX– (RS-485–) signal in the BACnet MS/TP (RS-485) network. |
|
6 |
SHIELD |
Convenience terminal to interconnect two shield drain wires (incoming and outgoing). There is no electrical connection in the device. The shield should be connected to ground at only one location and that is recommended to be at the automation server. The shield should not be connected directly to the RET terminal on the automation server. The transient energy on the drain wire should be conducted to ground and not through the automation server. |
