ETHIO6I6PR-2I give 6 digital switch channels to a wet contact 6 and electromechanical relays from form A. It has optical isolation to 3000 VDC of the transient over-voltage protection and has no channel-to-channel isolation. Each input channel can be used as a 32-bit counter. Ignition value and ensure value for the relay is programmable.

Note: When connected inductive loads to the relays, there may be a large electromotive force when the relay is activated because of the energy stored in the load . These flyback voltages can damage the relay contacts and shorten the lifetime of the relay sharply. Limit these flyback voltages at your inductive load by installing a flyback diode for DC loads or metal oxide varistor to vekselstrømsbelastninger.
