For a description of the LEDs belonging to this interface, see section
Important:
The port operates in IO-Link mode and the IO-Link standard
specifies a maximum current of 1 A through pin 1 and pin 3 without
additional measures. The use of standard cables allows lengths up
to 20 m as long as the current remains under 1 A.
Higher currents are possible and require a larger cable cross-
section or shorter cable length to keep the voltage drop for the
outgoing and return paths below 1.2 V.
Accessories
Use cables featuring an M12 A-coded male connector for mating; e.g. one
