Output Relay
An output relay is provided to control an external device with a rating of up to 1A, 30VDC or 0.5A, 125VAC. Three terminals are
provided to enable a normally-open connection (using the N.O. and C terminals) or a normally-closed connection (using the N.C.
and C terminals). Using the web interface, this relay can be set to change state (close the normally-open connection, or open
the normally-closed connection) either manually (page 29) or as a result of an alert state from one or more of the connected
sensors (page 22). The terminals for these connections will accept 16-26AWG wire.

network connection to the connector on the
ENVIROMUX
marked "Ethernet".

Note:
A recent design improvement
resulted in a change to the pinout of
the output relay in the ENVIROMUX-
MINI-LXO. Please be aware of the
change and note which version yours
is. The previous version is shown
