Inputs and Two-wire Transmitters
All unsed inputs should have their + and - inputs tied together
and to Commons to reduce noise. Tie power supply grounds
together to minimize ground loops.
Attention: This signal must be between +14.5V and common voltage
otherwise channel-to-channel cross talk can cause invalid input
readings and invalid under or over range readings.
The sensor cable must be shielded. The shield must extend
the length of the cable to the point of termination.
