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.
