Figure 10-5
Figure 10-6, 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
Figure 10-6, 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
Supply the sensors and U
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.
NOTE: Malfunction due to potential shifts
Make sure that GND of the actuators and GND of the supply voltage U
actuators, have the same potential.
This will prevent potential shifts, which can have undesirable effects on the function of the
station.
At the time of going to print, the IB IL 24 DI 32-PAC and IB IL 24 DO 32-PAC Inline
terminals are designed to connect sensors and actuators in 1-wire technology. For
connection examples, please refer to the corresponding data sheets.
