SymCom 50R-400-ALT Alternating Relay

SymCom 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 whn the lead and lag floats are both closed.

An adjustment knob provides the option to force one pump to run every time the float switch is closed. This is helpful when one pump has been removed for repair or for test purposes.

  • 480V inputs and relay outputs eliminate the need for a control power tranformer
  • Bi-color LED indicates the energized load
  • Compatible with single and dual float applications
