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
