5.8.2 Power PWR/IO Connector

Panel socket 4-pin.
Pin number Signal mark
1 GND(-)
2 VCC(+)
3 IN0
4 OUT0
Unit has to be supplied by a power supply specified as a Limited Power Source (LPS) accord-
ing to Annex Q of IEC 62368-1:2014. If the power supply/cable provided with device is not
used, always use the cables with minimum wire size (nominal cross section) 0.5 square mm
for power supply.
The power supply for the router must be between +9 V to +36 V DC, with current output
1 A. Protection against reversed polarity without signaling is built into the router. Note: The
protection against reversed polarity is lost if the negative pole is grounded!
The router is awakened after the power supply outage and subsequent renewal.

The PWR / IO interface is also designed for the processing of binary input and control
(setting) of binary output.
