Field-bus connection system for connection of sensors to field-bus e.g. in automation systems, has outputs of binary input circuit and A/D converter connected to microcontroller
A field-bus connection system (1) includes a first input (PIN4) connected to the input of a binary input circuit (10), a second input (PIN3) connected via a protection circuit (13) and a resistance (R) to the first input (PIN4). An analog-digital (A/D) converter (12) is connected to a point of connection (V) between the protection circuit and the resistance (R). The outputs of the binary input circuit (10) and the A/D converter are connected to a microcontroller (11) which is set up therefore, to output a digital output value to the field bus (2).
