4 I/O Box
4.3.4 Connecting the I/O Box to the
Voltage Supply
Connect the 12 Vdc to 36 Vdc connection line with the
terminal for the voltage supply. Connect the grounding of
the connection line to the "V" terminal and connect the
grounding pin (GND) if grounding is present.
Pin Assignment
V- / V+ Voltage supply 24 Vdc
(12 Vdc to 36 Vdc)
Diameter of the leads
For safety reasons, the leads for the electricity supply
must have a diameter of at least 2 mm².
