Questions & Answers

Can this isolated relay LMRL-100 be used to control 120V exhaust fans or do the exhaust fans require 24V low voltage contact points for integration with this relay?

Asked by: Anonymous
Greetings, The LMRL-100 requires a set of 24v AC/DC dry contacts for integration, it is not designed for 120v input

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.
