DCC - Model Series II (DPC2-5)- 11928-5 -Duplex Pump Controller

• Wastewater Pump Station Level Control
• Water and Wastewater Plant Level Control
• Storm Water Level Control
• Liquid Level Control for Tanks
• Holding Pond Level Control
• Most Liquid Level Control Applications

• Controls up to 2 pumps with built-in alternation and time delay between pump starts.
• Accepts 2 types of sensors including any 4-20 mA level transmitter and floats switches.
• Automatically selects a backup sensor in the event the primary sensor fails. If the primary sensor fails then the system will operate with a backup 4-20 mA signal sensor (optional) or backup floats.
• On, Off, High, and Low setpoints adjustable from front panel or remotely via serial port.
• 40 segment bargraph displays level, and setpoints.
• External digital level display available.
• Pumps, sensors, and alarms status indicators on front panel.
• Front panel test knob for simulated level input testing.
• 4-20 mA signal output proportional to level.
• RS-232 serial port for SCADA communications support.
• Uses non-volatile memory allowing system to retain program software and setpoints during power loss.
• Proven software that allows for easy setup and reliability.
• Custom software available from factory.
