Pulse output module

External power supply necessary Vcc = 3 – 30 V DC

Output current
≤
20 mA with a residual voltage of
≤
0.5 V

Open collector (drain)

The module consists of 2 programmable pulse outputs

Output 1:

Frequency:
≤
4 Hz

Pulse duration: 125 ms ±10 %

Pulse break:
≥
125 ms -10 %

Output 2:

Frequency
≤
100 Hz

Pulse duration/pulse break: ~1:1

As a standard the output 1 will give an energy pulse, the output 2 will give a volume pulse (at
heat meter or cooling meter)

At a heat meter with cooling tariff the output 1 will give an heating energy impulse and the
output 2 a cooling energy impulse (standard)

The pulse value depends on the digits after the comma of the corresponding display unit. As a
standard the value is always the last digit of the display.

The volume pulse value is freely programmable

Floating contact (electrically isolated)

The lifetime of the battery which is mounted on the module is 12 years.

To use the pulse output module an external power supply is necessary. Via a resistor the current has
to be limited to max. 20mA. At point 2 in the diagram the pulse will be given.
The outputs are marked “01 -
┴
” and “02 -
┴
” on the terminal and “Out1” and “Out2” in the display.
