Terminal labeling
The IO-Link device is connected to the IO-Link master via the terminals L+, C/Q and L-. The
IO-Link device is powered (24 V DC) via the two cables L+ and L-. The IO-Link device
communicates with the IO-Link master via cable C/Q. A 200 mA current is available at an
IO-Link port of the IO-Link master. If a current higher than 200 mA is required for the
IO-Link device, the terminals 1M and 1L+ can be additionally connected.
