HI520
Dual-Channel Universal Process Controller

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.

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 and valves.

Digital RS485 Output

Can daisy-chain up to 32 devices to a remote monitoring system.

Digital Inputs

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

Large LCD

The LCD displays measurement information along with indicators of potential problems. The DIAG key then provides details of the issue.

Data-logging

Store info at selectable intervals along with relay control settings and calibrations data. Up to 100 lots, each holding 8600 records. Transfer to a flash drive as a .csv file using the USB Type-C port.

Help Button

Using the help and diagnostic button (? DIAG) will provide information related to errors or in setup mode, information about settings.
