The SC1000 Station Controller is a panel mount SCADA ready pump controller designed to perform level control in a wide range of lift station applications. The SC1000 level controller operates the pumps based on selected setup values and the wet well level signal. The source of the level input signal is menu selectable as either a 4-20 mA transducer or a 10 point conductance probe. The SC1000 alternates the pumps, performs lag pump delays, provides high and low alarms, and has a variety control options available in the setup menu to customize the controller to the application. Connecting the RS-232 serial port (or optional Ethernet Port) to a SCADA system allows the lift station to be monitored and controlled remotely.
