CMeX12S
DIN-Mounted M-Bus master for up to 128 slaves
The CMeX12S makes it possible to expand your CMe Series with up to 128 extra M-Bus slaves. The unit can also be connected with any existing M-Bus system. The CMeX12S is equipped with the unique IR Pass Through function, making the product stackable.
Description
READY TO USE
The CMeX12S is ready to use with no configuration required in the field. The possibility of stacking the CMeX12S, enables one CMe2100 to handle multiple M-Bus 2-wire buses isolated from each other. After installation, the CMeX12S shows an indication if the installation was successful.
STANDARD OPEN PROTOCOLS
The standard open protocol design works with any software supporting the M-Bus standard. Its transparent M-Bus dataflow require no manufacture specific protocols.
FLEXIBLE
The CMeX Series contains modules with various functions to meet a great variety of customer demands. The series contains for example I/O modules and D/A modules to read input signals or control output signals.
COST EFFECTIVE
The modular and expandable design allows the customer to select a suitable level based on price and functionality. The initial cost is low and additional modules can easily be added to existing installations, which provides a future proof solution.
