Module IN-OUT (Pulse-in and -output)
The module IN-OUT is equipped with 2 pulse inputs and 1 pulse output.
The pulse inputs have the following specification:

The two pulse inputs can be programmed independently of each other with values of 1, 2.5, 10,
25, 100, 250, 1000 or 2500 litres per pulse.

Possible units are all the energy units available in the meter, such as kWh/pulse and GJ/pulse,
but also volume units like l/pulse, m³/pulse, or no units.

The input frequency is in the range 0 – 8 Hz, min. pulse duration 10 ms

Input resistance 2.2 M
Ω

Terminal voltage 3 V DC

Cable length < 10 m
The pulse output has the following specification:

External power supply Vcc = 3 – 30 V DC

Output current
≤
20 mA with a residual voltage of
≤
0.5 V

Open collector (drain)

Output frequency
≤
4 Hz

Pulse duration: 125 ms ±10 %

Pulse break:
≥
125 ms -10 %

Volume pulse value is programmable as desired (default: last digit in display)

No floating contact (not galvanic isolated)
Pulse input 1 is marked “I1 -
┴
” on the module and “IN1” in the display, pulse input 2 “I2 -
┴
” on the
module and “IN2” in the display (Fig. O, item 1).
The pulse output is marked “01 -
┴
” on the terminal and “Out1” in the display (Fig. O, item 2).
