The CMe3000 is a flexible and cost-effective M-Bus Gateway for Fixed Network. It is ready to use with all ABB DIN-mounted electricity meters and any M-Bus meter following the M-Bus standard protocol. The CMe3000 uses an internal web interface which allows it to be updated remotely. The flexible and versatile design makes it simply the most powerful TCP/IP M-Bus master on the market.
The CMe3000 requires no configuration in the field, which reduces both installation costs and the risk of handling errors.
The flexible design with the IR optical port makes it possible to add expansion modules on demand. For example, add a CMeX10 Series M-Bus Master to connect up to 256 extra meters. New expansion modules are constantly developed to meet new market demands.
The standard open protocol design enables fast integration into existing billing and reporting systems. Transparent M-Bus communication with TCP/IP works with any software supporting the M-Bus standard.
The CMe3000 provides some of the most cost-effective solutions for DIN-mounted meter installations. The quality and the number of options available serve to minimise the overall cost of the product over the course of its use.
The product has an intelligent Watchdog functionality to enable stable operation during a long time.
