2 pulse input module
Once installed the meter will display the icon for pulse inputs in menu 2 of the display. Accumulated
volume is only readable by communication. The two pulse inputs can be programmed independently of
each other (see specification for pulse input module).
Pulse value 0.001 m³ to 1 m³ per pulse
Voltage supply ≤ 6.0 V
Source current ≤ 0.1 mA
High level input threshold ≥ 2 V
Low level input threshold ≤ 0.5 V
Pull-up resistor 100 kΩ
Pulse length ≥100 ms
Maximum frequency ≤ 5 Hz
Pulse inputs According to EN1434-2, section 7.1.5 (Classification of pulse input
devices Class IB)
Battery life time 16+1 year
* Suitable for both electronic switch and Reed contact.
