  • Remote readings of registers of power meters, water meters, gas meters, heat meters (SmartCities applications)
  • Remote readings from measuring exchanges
  • Equipment monitoring
SENSECOM-IMD, CMD, OMD Use Cases Overview

SENSECOM-CMD

IoT communication unit for data transmission:

  • Possible options of input interfaces:
    • RS485 (Half or Full duplex)
    • RS232
  • galvanic isolation for models powered from mains. Battery powered models without galvanic isolation.
  • Communication protocols:
    • MODBUS
    • M-BUS (coming soon)
  • 15 adjustable registers for readings (1-2 messages per register)
  • Adjustable Reading interval 10min-24h
  • DIN-3U, IP20 or box, IP67-68
  • Mains supply (or from batteries – T models)
  • Communication to the nationwide IoT network SIGFOX
  • Connectable SENSECOM-WSH repeater for hard-to-reach places (basement, metal cabinets, etc.) up to 20m
