Multi-parameter controller for water treatment

10 March 2009

Bürkert´s multi-parameter controller mxControl 8620 is designed to automate the control of process variables within a water treatment system and reduces controller and instrument costs by as much as half. It integrates all control, monitoring and display features as well as data and event logging functions into one compact, easy to configure controller.

The mxControl 8620 is the first modular control system designed for seamless integration into countless chemical or skid control applications. It can easily be configured to display, transmit and record flow, pressure, pH/ORP, conductivity, turbidity, O2, O3, Cl2, level and temperature. It accepts standard 4-20mA inputs from these instruments and provides high level computations to optimise the water treatment process.

The control system is capable of processing up to four analogue, two RTD, eight digital inputs as well as five relays, four digital transistor outputs, and four optional analogue outputs – a total of 23 I/O – simultaneously.

The controller is highly software based. All standard modules can easily be loaded by SD card or from a standard PC via the USB interface.

Proportional, integral or cascaded temperature control with dual indication of process values and an open system architecture of the unit’s internal hardware and software make this device unparalled in its field. Even the operating security can be tailored to individual applications.
