The 12 relays extension board may be fixed to a IC Controller board to obtain a 16 relays controller.
Relays Rating is max. 24V AC/DC / max. 0.2A AC/DC.
Each relay outputs are NO (Normally Open) and CO (Common).
The 12 leds indicate the relay status and are lighted when the relay is activated (i.e. relay outputs NO-CO shorted).
The maximum board current consumption is 200 mA.
1- Disconnect the power from the intelligent controller.
2- Screw the supplied spacer at the corresponding controller emplacement.
3- Plug-in the 12 relays extension board to the ic controller board through the P8 connector.
4- Use the supplied screw to tighten the Relay board to the spacer through the corresponding hole.
5- Connect the wires to connector J10.
6- Verify that the Relay board is still properly plugged in into the controller and then power the controller.
