Features
For input channels, the data can be configured for:

Engineering units ×1

Engineering units ×10

Scaled-for-PID

Raw/proportional data
For output channels, the data can be configured for:

Engineering units

Scaled for PID

Raw/proportional data

Percent range
For input channels, the module uses a digital filter that provides high frequency
noise rejection for each input signal. The filter for each channel is programmable
allowing you to select from four different filter frequencies:

4 Hz

17 Hz

62 Hz

470 Hz
Channels are wired as differential inputs or single-ended outputs. One cold
junction compensation (CJC) sensor comes installed under the terminal block
(and is not accessible to the user) to enable accurate readings when using
thermocouple input types. The CJC sensor compensates for offset voltages
introduced into the input signal as a result of the cold junction where the
thermocouple wires come into contact with the terminal block.
Module configuration is done via the controller's programming software. The
module configuration is stored in the memory of the controller. Refer to your
controller's user manual for more information. The illustration below shows the
module's hardware features.
