Hello,
Summary:
I am trying to troubleshoot a 0-5VDC signal from a pressure transducer wired to a UAD1216 expansion board. Everything looks like it is wired correctly and I can confirm a voltage output from the sensor, but Base Station shows all channels as reading 5V.
Setup
-
ZUXPSR32xDPDTPROXR with an UAD1216 connected to the UXP port. 12VDC supply connected through barrel connector on the board.
-
3-Wire pressure sensor with 0-5VDC signal.
a. Excitation+ wired to “+” on 12VDC terminal strip on the Relay Board.
b. Excitation - wired to “-” on 12VDC terminal strip on the Relay Board.
c. Signal wired to UAD1216 Channel 0 terminal B. -
Both up/down jumpers on the UAD1216 are in the DOWN position.
-
Device jumper on the UAD1216 is in the “0” position.
Results
-
Pressure sensor is outputting 1.6V on signal wire.
-
Using Base Station software to monitor the UAD1216 with “UXP AD1216 Analog to Digital Conversion Command Set” screen.
-
“Monitor Device 0” is checked.
-
Clicking “Read 8-Bit 1-Channel at a Time” returns all 16 channels with “255 5V”
-
Clicking “Read 12-Bit 1-Channel at a Time” returns all 16 channels with “4056 5V”
-
Moving the “8-15” jumper to the UP position gives the same results.
Conclusions/Questions
-
It’s possible the wiring incorrect. From the description above can you confirm if the wiring is right? Is there a manual that shows wiring examples rather than a photo with captions?
-
It’s possible the main relay board isn’t communicating with the UAD1216. Is there a way to determine this with Base Station or some other software?
I know this is long, but I am trying to provide as much detail as possible to resolve this quickly. I have already combed the website without much success. If there is something I have missed, please direct me to the appropriate resource.
Please let me know if you need any other information as well as your thoughts.
Thank you.
