Model FX-8500C - Compound Loop Controller Brochure

The Foxcroft FX-8500C compound loop PID set point controller provides the vital link between chlorine analyzer, flowmeter, and chlorine feed device. Change chlorine feed rate instantly with changes in flowrate. Time-compensated changes based on residual feed back from the chlorine residual analyzer minimizes overshooting the desired setpoint. The unit has programmable reverse or forward control mode (into output summator) for Chlorine, Ammonia, or Sulfur Dioxide control systems. Options include Ethernet or Modbus® communication, or remote control from a central computer or SCADA.
