For sensor connection to the extension module, see its manual.
4. You can connect a sensor to an external thermistor relay the insulation of which is
rated for the main circuit voltage of the drive.

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 I/O
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 (18 °F). If a
better accuracy is needed, use the FAIO-01 analog I/O extension module (option +L525).
