|-
| style="text-align: left; vertical-align: top;" |A fuel tank level sensor which indicates the approximate fuel level on the driver's indicator panel exists in most cars. If the sensor returns analogue signal proportional to fuel level it can be connected to {{{model|FMB140}}} Analog input. After connection to the tank fuel level sensor a calibration is needed because most fuel tank sensors are not linear. Calibration is performed by measuring voltage values resulting from the volume of fuel in tank.

|-
| style="text-align: left; vertical-align: top;" |Alarm buttons, door sensors, ignition, etc. have two output states: high or low. {{{model|FMB140}}} Digital inputs are used to detect these states.

The FMB140 does not have a 1-Wire Power connection, so most other 1-Wire devices compatible with FMB1YX family are uncompatible with the FMB140 (DS1820, DS18S20 and DS18B20).}}}
