IP-LCM Connections

IP-LCM connectors

Inputs

There are 8 inputs. Each of them has a corresponding selector switch, with which one can select 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 contact terminals, Normally Open (NO), Normally Closed (NC) and Common (COM), are labeled in the silk print of the PCB.

IP-LCM relays

Relay 5 to 8 has a corresponding selector switch. With this switch one can select if the Contact Set #1 should provide try concts, or if it should forward power from the power forwarding connector.

Relay contact 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.
