Channel Configuration Worksheets 91
Select your bit configurations. Write them down at the bottom of the worksheet. Use one worksheet for
each channel.

Configure the channel for the
input type connected to it. Valid
inputs are thermocouples and analog
input signals of ±50 mV and ±100 mV.
You can configure the channel to read
the cold-junction (CJC) temperature.
When reading the CJC temperature,
the channel ignores the physical input
signal.

00 Select the channel data format
from: Engineering units (EU) x1 or
x10. For EU x1, values are in 0.1
degrees or 0.01 mV. For EU x10,
values are in whole °C or °F or
0.1 mV. Scaled-for-PID (value is
the same for any input type).
Proportional input signal range is
scaled to 0…16,383 counts.
Proportional counts (value is
same for any input type).
Proportional input signal range is
scaled to ±32,767 counts. For more
information, refer to page 49.

Mode
Zero 00 Select module response to a
detected open-circuit from: Zero
to force the channel data word to
zero. Upscale to force the channel
data word to full scale. Downscale
to force channel data word to low
scale. Important: A bit selection or
1 1 is invalid. For an open CJC
thermistor, mV channels are not
affected. Important: The module
requires 500 ms or one module
update to flag the error while it
ramps the channel input.
