IP-LCM Connections

IP-LCM connectors

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 lebeled in the silk print of the PCB.

IP-LCM relays

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.
