PadPuls M2

The 2-channel pulse adaptor PadPuls M2 allows the use of up to 2 meters with pulse output as M -Bus slaves.

  • Two separated pulse inputs

  • Safe detection of up to 15 pulses per second at each input

  • Pulse debouncing

  • Pulse value free adjustable

  • Plug-in terminals simplify the installation wiring

  • Unit free selectable (e.g. Wh, kWh, MWh, kJ, m3, l,...)

  • Counter length: 8 decimal digits

  • Due-date function with integrated realtime clock

  • One yearly value and 15 monthly values (optional)

  • M-Bus protocol according to EN13757-2 and -3

  • Fully parameterizable by M-Bus, including overwrite protection

  • Transmission rate: 300 and 2400 baud with auto baud detection

  • Fully operable in case of M-Bus failure by integrated battery

  • Case for wall mounting W x H x D: 80 x 80 x 52 mm

  • Two battery options available

  • Protective class IP 54 (IP65 is possible)

The devices of the PadPuls M2 series adapt up to two conventional meters with pulse output to a M-Bus system. The two counter inputs are nearly free parameterizable and fit in already existing installations.
Optionally the user can activate a tariff function, by which energy or volume pulses can be accumulated in separate meter readings for primary and secondary tariffs. O one pulse signal and one changeover signal for the tariff are required, for example out of a ripple control receiver from the electricity supplier.
The integrated battery ensures that the impulse adaptor is fully operable, even if the M-Bus network fails. Additional security is provided by the periodic saving of the meter readings in nonvolatile memory.
