PCI-1730 ECOM and EGND Connection Question

Real situation:

1. I can measure 12V at ECOM(pin28) when floating.

2. I know EGND for IDO usage.

Question :
I just have only one external 24V power supply, will it be OK to connect ECOM and EGND together for IDO and Wet contact DI detection at the same time?

Answer:
Yes.

Notice:
IDO may have voltage spike on GND when switching an inductive load. This spike may cause DI detection stability problem.
