3-channel controller for potentiostatic and amperometric sensors, for measuring and controlling pH, free chlorine or redox and for measuring and indicating temperature.

General information:

  • Microprocessor unit with backlit LC display
  • Settings via keypad
  • Signal input for redox and pH electrodes, with BNC connector
  • Signal input for amperometric sensors 0 … + 2000 mV, with 12 V - 24 V power supply
  • Signal input for amperometric sensors 0/4 … 20 mA, with     24 V power supply
  • Signal input for temperature sensors 0/4 … 20 mA, with 12 V power supply
  • Input for external dosing stop
  • Input for flow sensor, inductive proximity switch
  • Pulse input for flow meter
  • Direct calibration access
  • pH control in both directions
  • Two 0/4 … 20 mA analogue outputs, measurement or output value, max. 500 Ω (P or PID control)
  • Three relay outputs, 2 A / 250 V AC for cyclic mode
  • Four freely programmable relay outputs, e.g. for alarm signals, dosing pumps or final control elements
  • One printer output (e.g. for printing reports), RS232 interface
  • Communication via RS485 interface (Modbus protocol)
  • RJ45 modem interface for GSM, Ethernet or WiFi communication in case of remote monitoring (optional)
