Priority change relay from Finder

28 March 2012

For installations needing duplicate equipment sets, for reasons of operational security or to meet peak loading demands, Finder has introduced a flexible multi-function priority change relay, providing convenient control of main and secondary systems.

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 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.

Available in 24V and 110V to 240V AC/DC versions, the 72.42 relay supports a wide supply range and with two independent NO output contacts rated at 12A, 250VAC, is capable of directly switching single phase motor loads up to 0.55kW.
