Temperature
Description
The aintemp I/O module provides two analog input I/O channels for the circuit board
temperature of the SCADAPack controller.
 Channel 1 data is circuit board temperature in degrees Celsius.
 Channel 2 data is circuit board temperature in degrees Fahrenheit.
The ambient temperature input measures the temperature at the controller circuit board. It is
useful for measuring the operating environment of the controller and returns an integer value
in the range –40 to 75 or –40 to 167. The temperature reading represents temperatures in
the range -40°C to 75°C or -40°F to 167°F. Temperatures outside this range cannot be
measured.
Data for the I/O channels may be connected to user-defined variables with the I/O
connection editor. The connected variables are updated continuously with data read from the
controller.

Notes
The temperature sensor returns a value in the range -40°C to 75°C or -40°F to 167°F.
Temperatures outside this range cannot be measured.
The SCADAPack 100 controller uses the complex equipment sp100 module to access the
RAM backup battery voltage. See the sp100 IO connection for further details.
Refer to the SCADAPack System Manual for further information on controller circuit board
temperature.
