• 5-year warranty

• Made in the USA

Alternating relays are used to alternate between two loads and are
commonly used in duplex pump-up and pump-down applications
to balance the runtime of both pumps.

The ALT-xxx-1-SW alternating relays are 11-pin octal base plug-ins,
available in two different single-phase voltage ranges. The ALT­100-1-SW is used for 95-120VAC applications and the ALT-200-1­SW is used for 190-240VAC applications. Both models are designed

for a single oat input and feature two isolated Form C relays

(DPDT) outputs with two LEDs to indicate the energized load.

The ALT relays have a built-in debounce time delay that prevents

the relay from changing state if the oat momentarily bounces, and
they have a built-in switch to manually force a specic load (pump)
to operate each time the input oat closes. This is helpful when

performing periodic maintenance or pump repair.
