12.5.3 The various connection methods for sensors and actuators

1-wire technology Figure 12-8 1-wire termination for digital devices

Sensor Figure 12-9, detail A, shows the detection of a sensor signal schematically. The SW

switch provides the input signal. The sensor signal is led to terminal point IN1. The sensor

is supplied by the voltage U

S

.

NOTE: Malfunction due to potential shifts

Supply the sensors and U

S

of the Inline station from the same power supply. Make

sure that there is at least one common GND as reference potential.

This will prevent potential shifts, which can have undesirable effects on the function

of the station.

Actuator Figure 12-9, detail B, shows the connection of an actuator. The actuator is supplied by

output OUT1. The load is switched directly via the output.

NOTE: Malfunction due to potential shifts

Make sure that GND of the actuators and GND of the supply voltage U

S

, which sup-

ply the actuators, have the same potential.

This will prevent potential shifts, which can have undesirable effects on the function

of the station.

The following Inline terminals are designed to connect sensors and actuators in 1-

wire technology:

– IB IL 24 DI8/HD-PAC, IB IL 24 DO8/HD-PAC

– IB IL 24 DI8/HD-ECO, IB IL 24 DO8/HD-ECO

– IB IL 24 DI 32/HD-PAC, IB IL 24 DO 32/HD-PAC

For connection examples, please refer to the corresponding data sheets.
