Siemens UH50 Series Configuration Instructions page 8

The pulse module permits the output of pulses that
can be derived from the quantity of energy, the
volume, tariff register 1 or tariff register 2. Two
channels are available whose functions can be
parameterized with the service software.
Output takes the form of standard pulses or "fast
pulses". The pulse duration is identical for channel 1
and channel 2.
Note: If two pulse modules are plugged, please note
the restrictions!

Pulse duration
Pulses for operating states:
"Ready" pulsed "conducting", i.e.
0.1...0.25 ms pulse duration,
500 ms period
"Fault" constantly "non-conducting"
Fast pulses
Note: In battery operation, a D cell is required!
For applications, such actuating controllers or as
flowrate transmitters, higher pulse rates are required.
The parameters required for this (pulse significance,
pulse duration), can be configured with the service
software.
The maximum pulse frequency is 33 Hz.
The following can be set:
• Pulse type: "linear" or "scaled" pulses *)
• Pulse output: energy or volume
• Pulse duration, if only 1 pulse module is fitted:
from 2 ms to 100 ms in steps of 1 ms;
Pulse duration, if 2 pulse modules are fitted:
von 5 ms to 100 ms in steps of 5 ms
The pulses can be received and evaluated with a
suitable device. The settings must be made in
accordance with the information on the data sheet of
the controller.
*) Linear pulses are output proportionally to the
measured value. In the case of scaled pulses, the
number of pulses at the upper and lower end of the
range can be defined. In this case, the pulse
receiving device can detect, for example, a
connection error.
