RP-V-5C-M Screw Terminals

The RP-V-5C-M model has five I/O points and the controller is equipped with 11 fixed screw terminals and a 3-position removable screw terminal block.

Recommended screw tightening torque for fixed screw terminal blocks: 0.56 to 0.79 Nm (5 to 7 lbf.in)

Recommended screw tightening torque for removable screw terminal block : 0.5 Nm (4.5 lbf.in)

The 11 fixed screw terminals are used as follows:

  • Two screw terminals for the power input

  • One screw terminal for earth ground input

  • Four screw terminals for the two universal inputs/outputs of type Ub

  • Four screw terminals for the three solid-state relay (SSR) outputs

The 3-position removable screw terminal block is used for connection to the BACnet MS/TP (RS-485) network.

COM

Common connection for DO1, DO2, and DO3

The COM terminal can be connected to 0 to 24 VAC or -30 VDC to +30 VDC.

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.

13

RS-485–

Connection to TX/RX– (RS-485–) signal in the BACnet MS/TP (RS-485) network.

14

RS-485+

Connection to TX/RX+ (RS-485+) signal in the BACnet MS/TP (RS-485) network.
