Features
Technical specifications

Modems MCL (controllers) are applied in smart metering systems (electricity, gas, water, heat or other utilities) and automated data reading systems. The device has a passive current loop interface (CLin) for a connection of external systems. Modems are applied into data exchange systems where "peer to peer" architecture is used.

GSM network CSD/GPRS technology

Transparent or TCP/IP protocols

20 mA "Current Loop" or RS485 interfaces are used for data read out

RS232 is used for parameterization of the device

Modem supports various manufacturer`s meters

Modem is mounted under terminal cover of meter ot fixed to 35 mm DIN rail
