Hi,
I am working with a 2-10VDC output on a VFD and using a resistor to convert to mA.
We put a 500ohm resistor on the output per the VFD instruction manual, however I am now seeing that the mA is less due to the increased resistance from the Transmitter.
The 500ohms is the total loop resistance needed.
What is the internal resistance of the 2-channel transmitter, per channel, so that I can get the right transistor size?
