172QR - Quad Relay Module


E-Plex output module with four normally open isolated relay contacts, packaged in a small din rail mountable box. An auxiliary power connection is required to power the relays.
Each relay can drive up to 130 VAC at 10 A with no external components. The module is available in 12 V or 24 V configurations, and operates at the full E-Plex voltage range.

Frequently Asked Questions

When I interrogate or initialise the module, E-Logic reports "Time out reading module key at address XX!", is my module faulty?

No. As part of the interrogate and initialise procedures, E-Logic requests a piece of information called the module key. However this feature has not always been present, and the 172QR has not yet been updated to support the command. This change is not critical, so it will only be made once other firmware changes are required.
