4-RELAY OUTPUT MODULE - POWER BAY
The 4-Relay Output Module incorporates four Form-C relay outputs and the I/O Combination Module incorporates
two Form-C relay outputs.
Important Output Relay Connection Restrictions
1.
Do not connect output relays to a device that draws more than 2 amperes of current. Output power: output
relay contact, resistive load - 120 Vac, 2 A max.; or 24 Vdc, 2 A max.
2. Alarm relays cannot be used for flow control. Alarm relays provide only a momentary closure and cannot
actuate flow control devices such as valves and pump motor relays for extended periods of time.
Connect the wires from each external device to the appropriate terminals on the output module [see Figure 66].
