Pulse doubler

multisys D2 1DI2DO 1

multisys D2-1DI2DO / Pulse doubler: Splits the pulse output of an electricity meter to be able to connect 2 pulse counters.

 Meters and measuring devices of different media usually have a pulse output, which output pulses proportional to the energy. This standardized (EN 62053-31) S0 hardware interface is used, for example, to transfer consumption measured values to a building automation system.

But not only the GLT or ZLT needs this pulse, also PV systems, energy data management systems, heating controls, BHKW, energy optimization systems etc. access this pulse.

What to do if the pulse is needed, but it is already "occupied" by another system?

This is where KBR's "pulse doubler" comes to the rescue. The electronic coupling stage is a DIN rail device for standard rail mounting with 2 division units. It has one input for the S0 pulse and two potential-free S0 outputs. The power supply unit is already integrated in this device and is connected directly to 230 V. An external power supply unit is therefore not required. An external power supply is therefore not required.

Installation and connection is simple, as no programming is required here.

Examples of use:

S0 pulse from EVU meter simultaneously for two pulse pickups such as:

  • Control technology
  • Energy optimization
  • Energy data management
  • Data logger
  • etc.



  • Compact design
  • Integrated power supply
