The DUPLEXER (010-120-122P) is a low-cost SCADA ready, Modbus RTU Protocol plug-in pump controller designed to perform level control for duplex lift station applications. The level inputs of this dual pump controller can be connected to either four float switches or to a conductance probe. This 2 pump controller provides a 10-second power-up start delay, 5-second lag pump delay, and duplex alternation. LEDs provide power-on status, level input status, pump call status, and high-level alarmstatus indication. Pump 1 & 2 call and high-level alarm relays are provided. HOA and lead select toggle switches are also provided.
