Relay Assignments

The 9125 controller has the option of using eight relay outputs. All of the relays have a positive common terminal and independent negative terminals. All of the relays are configured in a normally closed position except relay number eight, which has both a normally closed (NC) and a normally open (NO) terminal.  These relays can be configured to work with events, alarms, loops, burnoff and alarm combinations.

 

Relay Output Terminals

Relay Output 1 – terminals 7 and 8

Relay Output 2 – terminals 7 and 9

Relay Output 3 – terminals 7 and 10

Relay Output 4 – terminals 7 and 11

Relay Output 5 – terminals 7 and 12

Relay Output 6 – terminals 7 and 13
