Hi there!
I have a 0-10VDC signal coming from a Turck MS25-Ui rotation montior which was being read by one input channel (differential) of an Eaton XIOC-4AI-2AO-U1 analog in/out module. Impedence 40kOhms.
I paralelled with that two channels from the NI 9205 using the same common. These are 10GOhms each.
Voltage signal on the Eaton PLC is going bye-bye. Is it because the impedence difference? I thought voltage could be paralelled without loss regardless of load...
Is there a simple way to fix this? Plenty of room for extra hardware if needed...
I don't HAVE to split the signal three ways -- I was using two channels on the NI 9205 because I want to sample the same signal at two different rates and don't believe I can create two tasks for the same input using DAQmx. That's probably wrong too, but I'm new at this.
Thanks very much for your support!
