How to control SSRs using NI9264?

[hwips]

Hi, all
I want to control 18 SSRs (CSW-2410) using 2 units of NI-9264.

But, I could not output voltage correctly. For example, measured voltage is about 2.8V even though I connect NI-9264 to SSR and set 10V.　

This is final problem I have. Does anyone have a good idea?

Thanks

Typical input current is ~10mA for the SSR:

The 9264 output current is limited to ~4mA typical, it is unable to drive the SSR and thus why you may be seeing a reduced voltage output- it is overloaded.

add a transistor as a voltage follower or open collector

and add a 12V powersupply

or use a DIO card that can drive the current...
