Connector overview
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 5V, 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.
Each output has a LED which indicates if the relay is active or not.
Relay 5 to 8 has a corresponding output selector switch. With this switch one can select if the Contact Set #1 should provide dry contacts, or if it should forward power from the power forwarding connector. Contact Set #2 will always provide dry contacts, regardless of the position of the output selector switch.
- Left position: Contact Set #1 provides dry contacts.
- Right position: Contact Set #1 forwards power from the an external power supply connected to the IP-LCM unit. When the PSU is connected with the polarity as indicated in the drawing above, the "+" will appear on the Com terminal, and the "-" will appear on the NO-terminal when the relay is active. When the relay is in idle, the "-" will appear on the NC-terminal.
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)
