3.4.1.3 Expansion Card “C” Input Configuration
Expansion Card C contains 24 digital NO/NC inputs.
While units will vary depending on individual configurations, Expansion Card C is typically
numbered 1.1-1.24, 2.1-2.24, etc.
This page will be displayed when configuring inputs for Expansion Card C. It is similar to the
FMS Main Board Input Configuration page – see 3.4.1.1, “Main Card - Input Channels 1-8”
on page 45 —with the following exceptions:
♦ The Input Type options do not include Analog 4-20mA since Expansion Card “C” only
accepts dry contact inputs.
♦ The Gain, Offset, Hysteresis, Unit of Measure, High Limit 2, High Limit 1, Low Limit 1,
and Low Limit 2 are not available since Expansion Card “C” does not accept analog inputs.
♦ The option for Individual Ground Type (digital input only) is removed. Expansion Card
“C” accepts Individual and Common Ground inputs; however, it does not require any
software configuration.

3.4.1.4 Internal Temperature and Internal Humidity Configuration
Internal temperature and humidity sensors are optional, and are not included on all FMS
configurations. Internal Temperature, Ch. 105, and Internal Humidity, Ch. 106, have the same
options as a standard channel configured as an analog input, but the gain value cannot be
changed-it has a fixed value internally. The Input Type for Internal Temperature is used to
specify and display the input in Fahrenheit or Celsius.
