Overview
DI FO is an electronic control unit for colorimeters and chlorine/pH/Redox/temperature analysers, providing configurable relay outputs and multiple control modes for continuous monitoring and dosing in water treatment and pool applications.

Highlights

• Kit included
• Multilingual manual
• Simplified installation
• Compliant
• Recyclable packaging

Key features

• Configurable output relays: set-point, maximum/minimum alarms, PWM time-proportional control, PFM pulse-proportional control, automatic cleaning
• Optional 24 V low-voltage output to drive small dosing pumps or solenoid valves without additional transformers
• Galvanic isolation between inputs/microprocessor and current outputs
• OFF input to stop control relays and pause the colourimeter cycle; FLW input for flow monitoring; OK output for remote status signalling
• Display of alarms and diagnostics; date/time maintained without power and timed activation/deactivation slots
• Program and calibration data saved to non-volatile memory
• RS232C serial output for programming/dialogue with PC or PLC; connector options on request
