Relay Output Module Wiring

The Relay Output Module provides eight individually isolated, electromechanical relay outputs. Four of the outputs are Form-C, and the other four are Form-A. A schematic showing the relationship of individual Form-A relays and Form-C relays to external (user) connections is given in Figure 47.

Examples of Relay Output wiring as they relate to connections on the Terminal Block are shown in Figure 48.

Figure 47 - Schematic Example: Relay Output and External Wiring

Contact Rating

Maximum current/output: 4A at 250Vac/30Vdc with resistive load

Maximum current per module: No de-rating per module, but ensure compliance with maximum ratings for each output.

Required Output Fusing

Outputs are not fused in the Relay module. Install a fuse for each output at the field device that is appropriate for the load and the wire used.

Jumper Comb

A ten-position jumper comb, available for the AC Output Module, can be cut in half and used as shown in Figure 49 to reduce the number of wires required to connect the Relay Output Module to AC Neutral or to DC Common.
