Type 1094 EV
Technical Data
6.5.1. Frequency inputs / Gasoline pulses
5V
The volumetric flow of the delivered gasoline is measured by the piston
meter, converted into a frequency-proportional clock signal by the
gasoline pump computer and switched to the frequency input of the
controller (Fig. 4: ).
In the controller this clock signal is processed as the actual value of
the volumetric flow of the gasoline.
High-level pulse:3.4 V – 26 V
Low-level pulse:
0 V – +0,9 V
Input resistance:
> 10 kΩ
Max. input current:
5 mA
