Questions & Answers

I need to purchase twelve (12) DIN Rail Mount Adapter for the LMRL-100 (Isolated Relay Interface).  For reference, see the LMRL-100 cutsheet on the second page lower right-hand side.  Are these available without purchasing the Isolated Relay?

I've installed a LMRL-100 onto an existing room to control a third party load. When I discover the room with the LMCI-100 tool using the LMCS-100 version 4.10.3 build 2020-10-22 it does not see the relay. Is this device type not supported in the software?

Asked by: Joe P
The LMRL is not discoverable in LMCS.
