PadPuls M2W

The PadPuls M2W is a 2-channel pulse to Wireless M-Bus adaptor. The battery driven PadPuls M2W sends the data according to the OMS standard.

  • Wireless M-Bus according to standard EN 13757-4 Mode S, T and C
  • OMS conform and compatible (Spec 4.X.X)
  • Optional encryption Mode 5 or 7, AES
  • Two seperated pulse inputs (for reed contacts, optocouplers,...)
  • Save detection of up to 18 pulses per second on both inputs
  • Debouncing
  • Free adjustable pulse value
  • Free choice of units (e.g. Wh, kWh, MWh, kJ, m3,  l,...)
  • Configuration via USB-converter cable (NOT INCLUDED)
  • Transmission interval adjustable between 10 seconds and 2 hours
  • Battery supplied
  • Battery lifetime about 14 years at 15min transmitting
  • Distributionbox for wallmounting

The PadPuls M2W is used for the wireless integration of up to two conventional consumption meters with pulse outputs into a wireless M-Bus radio system. The two count inputs can be parametrized almost arbitrarily via an adapter cable and can be adapted to existing installations. With the PadPuls M2W meter readings of water, gas, electricity and heat meters, which do not have a communication interface, can easily be transmitted to a wireless M-Bus receiver. For integration into an existing wired M-Bus system, our Wireless M-Bus to M-Bus gateway RelAir R2M can be used.
