Analog Input, 16 Bit RTD, 4 Channels
Module Features
Channel Active
Each channel can be configured as either active or inactive.
If a channel is inactive, it is not scanned and a value of 0 is returned by the
module.
Input Units
Inputs can be measured as tenths of
Ω, tenths of °C, or tenths of ° F. The
default is tenths of °C. The measurable ranges for each type of input units are
displayed in the following figure.

Low Alarm Limit and High Alarm Limit
Each input channel can have a low alarm limit and a high alarm limit. If an input
reaches one of its limits, the module reports the actual value and reports an
alarm fault in the I/O Fault Table. Alarms do not stop the process or change the
value of the input.
Alarm limits can be set anywhere over the dynamic range of the signal. The
range for each is –32,768 to +32,767. The high alarm limit must be greater than
the low alarm limit. If alarm reporting is not wanted, alarm limits can be set
beyond the dynamic range of the signal so they will never be activated.
