SymCom Model ALT alternating relays are used to alternate between two loads. The ALT is commonly used in duplex pumping applications to balance the runtime of both pumps. The Model ALT-S is used in single high level float applications. When the float switch opens, the alternating relay changes state forcing the other pump to run the next time the float closes.

The Model ALT-X has an internal cross-connected relay and is used in applications where two high level floats are used. These floats are commonly referred to as lead and lag floats. The lead float causes the relay to change state each time it opens (identical to the float in the ALT-S application).

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 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 load.

The ALT-xxx-3-SW alternating relays are 8-pin octal base plug-ins, available in two different single-phase voltage ranges. The ALT-100-3-SW is used for 95-120VAC applications and the ALT-200-3-SW is used for 190-240VAC applications. Both models are designed for three float inputs (lead, lag and stop floats). The lead and lag floats actuate latching relays that release when the stop float actuates. The units feature two LEDs to indicate the energized load(s).

The ALT relays have a built-in debounce time delay that prevents the relay from changing state if the float momentarily bounces, and they have a built-in switch to manually force a specific load (pump) to operate each time the input float closes.

SymCom Model 50R-400-ALT alternating relays are used to alternate between two loads, most commonly in duplex pumping and compressor applications to balance the runtime of both loads. When used in single float applications, the alternating relay changes state after the float switch opens*, forcing the other pump to run the next time the float closes. When used in dual float applications, the alternating relay will allow both pumps to run simultaneously when the lead and lag floats are both closed.
