NI9403 -> Driver -> Relay jitter

[m.gandler]

Hallo,

I have the following circuit:

NI cDAQ-9178 with a NI 9403 Module (32 Digital I/O) -> Driver IC -> 5V Relay (with 230V~ contact voltage).

If  I turn the Channels to Output with "Measurement and Automation" it works fine.

But if I restart the cDAQ it loses his settings and the relays begin to jitter.

I have tried it with pulldown resistors but it didn't work.

Has anybody an idea??

Hello,

does every channel jitter?

How long does it jitter?

So you set the Channels to Output in MAX and restarted the

cDAQ, just to test it.

The settings from MAX were lost and than it began to jitter, correct?
