I have a Tri-Plc T100MD-888+ PLC. It has Analog 0 - 5 volt input, and 5 volt reference voltage available. I have a fuel level sensor that is 0 - 90 ohm range to interface, only need around 50 or so steps, and can handle calibration/non-linearity with lookup table or Basic programing. Presently there is 30 feet of Cat-5 cable in metallic conduit to the remote location, I would prefer signal conditioning at the PLC end of the cable.
Also what would be the easiest way to get temperature readings, say -30F to +130F, nearest degree resolution would be more than enough.
Spent all the budget on the PLC, buying a $250 signal conditioner is not an option.
