Bürkert mxControl 8620 multiparameter controller for water treatment

Bürkert’s multiparameter controller mxControl 8620 is designed to automate the control of process variables within a water treatment system, reducing controller and instrument costs by as much as half. The product integrates all control, monitoring and display features as well as data and event logging functions into one compact unit. It is suitable for primary water treatment processes or ancillary processes in manufacturing, mining and general industry.

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

The system is capable of processing up to four analog, two RTD, eight digital inputs as well as five relays, four digital transistor outputs and four optional analog outputs simultaneously. Sophisticated electronics and control algorithms ensure optimum process control is maintained with minimal operator intervention.

Parameters are loaded by SD card or from a standard PC via the USB interface. An optional ethernet interface can be used to configure and parameterise the controller remotely or be used to send email or SMS alerts in the event of an alarm situation. All important variables and parameters may be raised via five soft-touch keys, with the operator able to grant varied access via the built-in security system. The product provides continuous online monitoring and process control, achieving high precision, improved reliability and QA reporting.
