Burkert mxControl 8620 multiparameter controller

Click2Contact

The multiparameter controller mxControl 8620 is designed to automate the control of process variables within a water treatment system and reduces controller and instrument costs. The controller integrates all control, monitoring and display features as well as data and event logging functions into one compact unit.

The controller is the first modular control system designed for seamless integration into countless 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 to optimise the water treatment process. The 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, eight digital inputs as well as five relays, four digital transistor outputs and four optional analog outputs - totalling 23 I/O - simultaneously (model dependent). Its 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.
