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.

Power relays

Two 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.
