IP-LCM Connections
From Zenitel Wiki
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.
Relay 5 to 8 has a . 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.
