Your benefits

  • Transparent mode of operation:
    Unchanged transfer of read-out data to the communication device
  • IR interface for modular extension:
    No need to replace the level converter when connecting additional measuring points, investment protection
  • RS232 interface for communication with PC:
    Transparent communication between level converter and PC
  • 100-240 V AC mains power required:
    No extra power supply necessary
  • Operating status display via LED:
    Easy on-site analysis and troubleshooting

Applications

  • Remote supply and remote reading of M-Bus end devices
Zaehlerfernauslesung M Bus Pegelwandler C Me X 1

Properties

  • Signal converter from M-Bus to RS232
  • DIN mounted, modular and expandable – future proof solution
  • Stackable modular design M-Bus level converter for 32, 64, 128 or 256 M-Bus end devices with a standard load of 1,5 mA
  • With the IR-Enabler (CMeX40) it is possible to extend existing M-Bus installations for additional M-Bus loads
  • Several extension modules (additional M-Bus loads) which are mounted to the right (IR interface) of the module are available
  • M-Bus protocol according to EN 13757-3
  • Transfer rates: 300, 2400 Bit/s
  • M-Bus short-circuit protection
  • 100-240 V AC power supply
  • Operating indicator with LED

1) Can be used as an extension module (additional M-Bus loads).
2) The maximum possible network reach (entire cable length) as well as the distance to the M-Bus end devices depends greatly on the network topology, the number of connected devices, the cross-section of the used cables and the transfer rate.
