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.
2 pulse output module
Once installed the meter will display the icon for wired communication in menu 2 of the display.
Pulse 1 (energy*) + terminal 16, - terminal 17
Pulse 2 (volume*) + terminal 18, - terminal 19
Pulse value*
Unit follow the display. Scaling follow least significant digit of the display
(default setting can be changed via SonoApp)

Battery life time 16+1 year
Cable length Max 25 m
Alarms
E32 activates in meter if:
1) Module battery is empty
2) When no. of delayed pulses exceeds 5000 (incorrect scaling)
*Default setting. Can be changed via SonoApp.
