Simplex Controller: Model SIM-120-001P

The Simplex Controller is a microprocessor based single  (1) pump controller with a high and low level alarm. A zero crossing detector  switches the outputs on or off as the line voltage crosses zero to reduce noise and spikes. The simplex controller requires a minimum of four (4) float switch inputs.
