The FlexIO-M Thermo is likewise a thermocouple measuring module for electrically isolated temperature measurement. This variant offers eight type K thermocouple connections.

The FlexIO-S Analog measures voltages up to ±60 V and transmits the values on a CAN bus. Voltages of up to ±10 V can also be simulated to power sensors.

With FlexIO-S Digital , data on a CAN bus can be converted into digital signals for status display or to switch external peripherals. Additionally, digital inputs can be read-in and their signals mapped and transmitted on the CAN bus. For the purpose, the hardware features a CAN interface as well as eight high-side and eight low-side channels which can be individually configured optionally as inputs or outputs.
