CMeX40
DIN-Mounted M-Bus I/O module
The CMeX40 is an M-Bus slave module with one input and output. It uses standard M-Bus 2-wire connection and requires no separate power supply. The product can be used as a remote relay and also to monitor a digital input signal.
Description
READY TO USE
The CMeX40 is ready to use with no configuration required in the field. It can be connected to a CMe Series master, or any M-Bus master following the M-Bus standard. The CMeX40 can control up to 230 VAC 8A.
STANDARD OPEN PROTOCOLS
The standard open protocol design works with any software supporting the M-Bus standard. It allows any existing M-Bus system to use the product without any proprietary solutions.
COST EFFECTIVE
The modular and expandable design allows the customer to select a suitable level based on price and functionality. The low initial cost and the possibility to add modules to existing installations provide a future proof solution.
