10.2.3 Digital inputs
SIMEAS Q80 7KG8080 has four digital inputs which are electrically isolated from the measurement system.
These mainly serve to process 230V
eff
voltages, but it is also possible to monitor lower
DC or AC voltages. The terminals are designed
for connecting a cable.
For appropriate cable cross-sections, please
see the
for the digital
inputs.
Level detection and LED
If the signal is above the switching
threshold (typ. 16 V), the state of the input
bit = 1 is displayed and the LED shines
green.
Below the switching threshold (typ. 16 V),
the state is = 0 and the LED is off. Below –
16 V the LED shines yellow.
