Inputs
Each of the 8 inputs has a corresponding selector switch, which selects between a dry closing contact or an active input.
- Left position: The input requires an active signal, typically 5, 12V or 24VDC. The input is galvanic isolated with an opto-coupler. Polarity as indicated on the drawing.
- Right position: The input requires a dry contact
Outputs
There are 8 relays, each with two sets of changeover contacts (DPDT). The changeover contacts, normally open (NO), normally closed (NC) and common (COM), are labeled in the silk print of the PCB.
From the left side the outputs are numbered as pin 17 to pin 24. Each output is a dual pole relay with normally open, normally close and common available on the pin header.
The bottom four outputs each has a corresponding switch. This allows forwarding power from the power forwarding connector to the relay normally open and common on each output.
Relay ratings:
- Outputs: DPDT (Double Pole Double Throw). NO (Normal Open), NC (Normal Closed), COM (Common)
- Switched voltage: < 250VAC Rated (400VAC Max)
- Switched Voltage: < 2000 VA max
- Switching Current: < 8A rated (15A max, 4s)
Indicators
Each output has a LED which indicates if the output is active or not.
