Bürkert mxCONTROL 8620 multiparameter controller for water treatment systems

Bürkert's multiparameter controller, mxCONTROL 8620, is designed to automate the control of process variables within a water treatment system. The 8620 integrates control, monitoring and display features, as well as data and event logging functions, into a compact unit. It is suitable for primary water treatment processes or ancillary processes in manufacturing, mining and general industry.

Designed for integration into a range of chemical or skid control applications, the controller 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, according to the company. The compact unit 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 and eight digital inputs as well as five relays, four digital transistor outputs and four optional analog outputs (totalling 23 I/O), simultaneously (model dependent).

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.

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. Users can download software modules from the company's website to suit each process.
