Caution
Damage to the device
The DC 24 V voltage on pin 1 does not have any special
protection against overload; the voltage is taken from the
main supply with protection against ESD and incorrect
polarity.
• Use the terminal only for the reference switch (sensor
supply).
Use of this connection as a power supply for other devices
is not safe.
The input for REF sensor signal complies in its electrical
properties with the input specifications in the appendix
“Technical data”.
