This table shows what temperature sensor types you can connect to the drive I/O
extension modules as well as the insulation requirement for the sensor.
Extension module
Type Insulation/Isolation
FIO-11 Galvanic isolation between sensor
connector and other connectors
(including drive control unit connector)
FEN-xx Galvanic isolation between sensor
connector and other connectors
(including drive control unit connector)
FAIO-01 Basic insulation between sensor
connector and drive control unit
connector. No insulation between
sensor connector and other IO
connectors.
FPTC- Reinforced insulation between sensor
xx connector and other connectors
(including drive control unit
connector).
Note: The inaccuracy of the drive analog inputs for Pt100 sensors is 10 °C (50 °F). If a
better accuracy is needed, use the FAIO-01 analog I/O extension module (option +L525).
