ALT-XXX-1-SW/ALT-XXX-3-SW

The ALT-xxx-1-SW and ALT-xxx-3-SW 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 ALT-100-1-SW is used for 95-120VAC applications and the ALT-200-1-SW is used for 190-240VAC applications. Both models are designed for a single float input and feature two isolated Form C relays (DPDT) outputs with two LEDs to indicate the energized loads. The ALT-xxx-3-SW alternating relays are 8-pin octal base plug-ins, available in two different single-phase voltage ranges.
