Priority change relay from Finder ensures even wear of alternating loads

For installations needing duplicate equipment sets, Finder has introduced a flexible multi-function priority change relay, providing convenient control of main and secondary systems.

Priority change relay from Finder ensures even wear of alternating loads

The 72.42 relay has been designed to alternate the duty of two sets of equipment to ensure even wear over time.

The relay can be configured to alternate the output duty either on successive applications of the supply voltage or via an independent input control signal. The 72.42 relay also provides a second input enabling both outputs to be forced on in response to a peak demand or an alarm signal.

To minimise any switch-on current surge, the 72.42 relay incorporates an adjustable output delay timer. Where maintenance of either equipment set is needed, the relay will ensure that only the healthy equipment set is made available.
