The SIGNAL PumpNode is a two-wire device designed to activate pump relays anywhere along the two-wire path.

All SIGNAL controllers, whether used in two-wire or multi-wire applications, are supplied with a PumpNode to activate the pump start relay.In two-wire applications, a second or third PumpNode can be located anywhere along the two-wire path to activate additional pumps, up to a total of 8.

PumpNodes provide additional flexibility to all SIGNAL control systems.
