5.5.2 Two Pulse Inputs
The Supercal 5 has two additional pulse inputs (A1 and A2) for connecting additional coun-
ters for cumulative electrical pulse counting. The two auxiliary electrical pulse inputs are
automatically inte-grated into the M-Bus, radio or optical telegram, and transmitted.
They enable the connection of a selection of hot water, cold water, electricity, gas or oil
meters.
Their individual parameterisation (normal and/or fast mode) can be set-up by software.
Technical Characteristics of the Two Pulse Inputs
Designation Description
2 inputs A1 at terminals 50/51
A2 at terminals 52/53
Input frequency normal mode Max. 5 Hz
Input frequency fast mode Battery operation max. 3,5 kHz
Mains operation max. 12 kHz
Input voltage 0 .. 30 V
Slow volume pulses 0,0001 - 99,999,999 l/Imp or Imp/l
Fast volume pulses 0,0001 - 99,999,999 l/Imp or Imp/l
5.6 Connecting Outputs
5.6.1 Two Open Collector Pulse Outputs
Two open-collector outputs (B1 and B2) can be used to display energy, volume, tariff 1, tariff
2, alarm and threshold values.
The maximum current per pulse output is 100 mA, the maximum voltage is 30V.
Their parameterisation (both in normal or fast mode) is carried out via the SuperProg soft-
ware.
Fast pulse outputs are used, for example, to control controllers. The maximum pulse
frequency here is 200 Hz.
These outputs are not galvanically isolated. For the connection to control systems we gen-
erally recommend the use of relay outputs.
