60 mA according to the specifications of the
IO-Link Master Unit
Ports 1 and 2 are calculated.
(Current consumption from power supplies of
IO-Link devices) + (Input current × Number of
inputs used)
= (50 mA + 50 mA) + (3.0 mA × 1 point)
= 103.0 mA
Port 3 is calculated.
(Current consumption from power supplies of
non-IO-Link input devices) + (Input current ×
Number of inputs used)
= 30 mA + (6.3 mA × 1 point)
= 36.3 mA
