As global competition increases for water treatment OEM’s, they are driving their suppliers to provide innovative lower cost control solutions. The latest trend is to incorporate multiparameter panel mounted transmitters (that were simply used as signal converters by sending analogue inputs to PLC’s) into single platform multi-parameter controllers.
Bürkert´s new multi-parameter controller mxCONTROL 8620 is designed to automate the control of process variables within a water treatment system and thereby 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. This saves time and space in cooling towers, reverse osmosis applications and boiler systems by allowing parameterization of a wide number of control variants via the integrated SD card slot, USP or connection via Ethernet. With an eye on both process safety and ease of use, the unit fits into a concept which can easily be customized exactly to any requirements and applications. The mxCONTROL 8620 is one versatile controller that can easily be configured to display, transmit and record flow, pressure, pH/ORP, conductivity, turbidity, O2, O3, Cl2, level and temperature. It 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 – simultane
