DCC - Model 12036 -Duplex Float Switch Controller (DFSC)
The Duplex Float Switch Pump Controller (DFSC) model 12036 is a control and display unit which automatically controls up to two single speed pumps. It is designed to be the heart of a duplex pump control system for lift stations and other fluid pump-down applications. The DFSC provides built-in pump alternation, pump start time delay, and pump disable inputs. It is designed to work with up to five float switches. The controller has six optically isolated inputs for seal leak sensors and thermal overload switches available with most submersible pumps. The DFSC includes the following status indicators on front panel: high alarm light, high alarm horn, low alarm, pump status, seal failure, temperature failure, and floats. The DFSC also includes an RS-232 serial communications interface designed to support SCADA systems using a variety of Modbus based communication devices giving the unit remote data acquisition, monitoring, and control capability.
