Description

Our advanced process controller, the HI520, is designed for applications requiring precise monitoring and control of four key water-analysis parameters: pH, ORP, Conductivity, and Dissolved Oxygen Waterproof Enclosure: IP65 (Nema 4X) rating ensures durability in harsh environments. Clear Status Indicators: Multi-color LEDs and an audible alarm provide immediate system feedback. Versatile Installation: Compatible with wall, pipe, and panel mounting kits (sold separately). Modbus Integration: Easily integrates into Modbus networks for remote monitoring, setup, and configuration.

Control Modes

Set points for control operations can be configured to be on/off, proportional, or PID types of control. The flexibility in programming allows for fine-tuning of a set point to be maintained with tight control preventing any overshoot and waste of chemicals.

Configurable Alarm System

Configurable for set points and temperature or activated by abnormal operation, a red Alarm LED will blink and can easily be seen from a distance. All relays configured for control are inactivated until the alarm state is resolved.

Auto-cleaning cycle

The cleaning function allows the ability to program one or more wash cycles and use the relays to activate valves, pumps or compressed air based on the type of washing that is required to maintain probes for reliable results.

Digital Inputs

Two digital inputs available for modes including disabling, cleaning and placing the controller into hold status​.
