Universal Analog Input Module (UAI) Wiring

The Universal Analog Input Module has eight inputs, which can
include any combination of the following input types: RTD, TC, Ohms,
Millivolt, Volt, or Milliamp. Figure shows wiring examples of each of
the analog input types. An example of wiring for eight TC inputs is
given in

ATTENTION:
To indicate sensor failure the Analog Input software will output
a warning if thermocouple resistance > 80 ohms. Use
appropriate gauge wiring to prevent inaccurate failure
warnings.
