Ambient Variations in Temperature
The F2-04RTD module has been designed to operate within the ambient temperature range
of 0°C–60°C.
Precision analog measurement with no long term temperature drift is assured by a chopper
stabilized programmable gain amplifier, ratiometric referencing, and automatic offset and gain
calibration.
Wiring Diagram
The F2-04RTD has a terminal block which simplifies wiring and can be removed to make
removal of the module possible without disturbing field wiring.
NOTE 1: The three wires connecting an RTD to the module must be the same type and length. Do not use the shield or
drain wire for the third connection.
NOTE 2: If an RTD sensor has four wires, the plus (+) sense wire should be left unconnected as shown.
