I have a question about wiring in the above-mentioned sensor to this PCB. First, I was hoping the board itself would power the sensor, but it appears that this isn’t the case. sigh
So following your diagram for a 2-wire sensor, you show a ‘Signal’ wire going to the positive terminal of the PCB, and the other wire going to the positive terminal of the external supply, and the negative terminal of the supply connected to the negative terminal on the PCB (for each channel). Omega’s datasheet/manual has the pins on the sensors labeled as such:
Pin 1: Supply +
Pin 2: Supply -
Assuming Pin 1 of the sensor is the ‘signal’ wire and goes to the positive terminal on the PCB and Pin 2 goes through the supply, I’m measuring -12V on the PCB terminal for the sensor channel when putting my negative meter lead on the negative terminal, and positive meter lead on the positive terminal. Is this right, or should I reverse the wiring?
Also, any chance of a rev update to the board so it supplies the power to the sensor directly? I feel like this would simplify things greatly for the end-user. Thanks!
