Digital Outputs Q1 And Q2 - MIB Flowmax 44i Operating Manual


Flowmax 44i
3.2.7 Digital Outputs Q1 and Q2 (Q2 only available with 8-pin plug)
The digital outputs Q1 and Q2 can be used as a pulse output, for signaling the
empty pipe message for controlling a dosing valve or to limit monitoring.
All outputs become high resistant if voltage falls below 16V. The digital outputs
become high resistant after about 100us for 2s when short circuit or overload.
Then it will retrying to actuate the output.

Important!
When using the dosing function the output should not be configured as normal
closed!
If the dosing output is configured as normal closed the valve will stay open
after the dosing batch.
