Power relays
Four 16A volt free contact relays are provided for switching a common input between a normally closed
output and a normally open output. The relay coil is powered by the 12vdc incoming supply on user
command.

Relay Power Rating
If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in
the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current
exceeding this region, the life of the contacts may be significantly shortened.
