I ordered your PCAN MicroMod FD Analog 1 for a measurement system and after reading the user manual etc. online I have one question;
Is there really only one GND for both analog inputs and outputs?
I'd have a couple of floating signals and I'm now afraid this doesn't work for me as I planned.
Thanks in advance.
please use Pin A11 (dual row I/O connector) GND for all Analog Inputs and Analog Outputs .
Internally this GND terminal is connected to GND-Pin 2 of the single row connector. But it is important to keep the Supply GND separat from the measurement GND A11.
The supply current to the module will create a voltage drop in the GND connection which would reduce the accuracy of the analog measurement.
In many cases it is not possible to connect all required GND cables into one position, therefor a distribution block can help to increase the number of GND position,
e.g. PTFIX 18X2,5-G GY - 3273438.
