The HI520 is an advanced process controller that can be configured for applications requiring monitoring and/or control of four main water-analysis parameters: pH, ORP, Conductivity, and Dissolved Oxygen.
This controller features a digital probe input(s) that automatically detects and updates the controller with the parameter that it measures.
The HI520 can also display two channels simultaneously.
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.
These controllers automatically detect supported digital probes and recognize the parameters that it measures.
Additionally, the HI520 introduces enhanced industrial control by operating a control-loop system whereby users have the option to run channel control either independently or configure to be triggered sequentially upon reaching the other channel’s set point(s) (1, 2, or both). The device operates a logical channel with built-in mathematical functions.
This function is intended for when the controller works as an analyzer for monitoring high/low parameter levels between two identical inputs with identical measuring configurations.
