FX-8500-S Single Loop Controller

The Foxcroft FX-8500-S Single-Loop Controller can provide unattended automation for chlorine residual application or virtually any other variable process. The FX-8500-S providesthe vital link between chlorine analyzer and chemical feed device in a “closed-loop” chlorine residual control environment. It allows instantaneous chlorine feed changes based on residual feed back from the chlorine analyzer.

The time compensation reflects the process time interval between chlorine injection and downstream chlorine residual sampling by the residual analyzer. This minimizes overshooting the desired setpoint.

Manual tuning of data parameters is easily done via the built-in keypad and display. Under certain conditions, the Autotune feature can perform self-tuning of data parameters
