Can I power two separate devices using one NI 9474

[Vishwaramesh]

I have written a code to use port0/line0 of the NI 9474 to supply current to a Thermoelectric heater which I pulse on and off using LabVIEW. 

Now, I want to power one more thermoelectric heater and heat them both to two different temperatures (so their controls in LabVIEW will be different cases). 

When I connect it to another port0/line x or even to a different NI 9474 (I have an extra), I get power to only one heater and the other doesn't function.

I am connecting all my modules to a cDAQ-9178 (can hold 8 modules).

Is there a way around this?

If I had to take a guess, I would say that you need a 24V power supply that can supply more current.

I am using a 12 V, 8.5 A supply. I think It may be enough. I remember reading that each chassis has only onw hardware clock. Will that affect my ability to run two separate digital o/ps from one chassis?

Hi,
