10 Output circuits
10.1 Digital output
An output pulse can be taken from the terminal strip at the rear side to operate of external counters. At every
increase of a selectable decade of the sum counter a pulse count corresponding to this increase gets gener-
ated.
If the total value was chosen e.g. with a resolution of 0.01kg, an impuls so is distributed with every increase at
0.01kg.
This pulse is genarated at a transistor with open collector output. Pulse width is 10 - 90ms (selectable).
The maximum switch current is 100mA.
When connecting a counter to the pulse output, it may be necessary to use an external pull-up-restistor. A
restistance of 5 to 10k
Ω
connected to terminal 40, are most times sufficient.
Make sure that this output isn't usually suitable for a further flow indicator as input signal because of the not
periodical pulse signal, please
