Process controller HI520

pHtemperaturemonitoring

ur 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. Hold Function Hold can also be triggered manually and by using and external digital input for disabling control mode when performing maintenance. 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. Relays Available with up to five electromechanical control relays and one alarm relay. Analog Outputs Up to four galvanically isolated analog outputs for control of pumps
