ME2X System Control Unit

Brand: Burkert Fluid Control Systems

The System Control Unit (SCU) of Type ME2X is the central control unit for Bürkert devices (valves, sensors, mass flow controller or displays), which are based on EDIP (“Efficient Device Integration Platform”). 

The basic version of Type ME2X consists of power-in and power-out modules of Type ME29 and a fieldbus coupler of Type ME23. 

This fieldbus coupler transmits the internal CANopen based communication of the Bürkert field devices to industrial standards for Industrial Ethernet and fieldbus. Additionally I/O modules from Type ME24 for Analog and digital signals can be used to expand the system. Through these standard signals other field devices without a fieldbus interface can be integrated. 

(For e.g. Analog sensors, valves etc.) With the help of the graphical programming sub-systems can be automated specifically to the customer’s needs. (For e.g. controlled mixing of gases, error monitoring through switching commands, timer switches etc.)
