Supply concept
The I/O hub TBIL-L…-16DXP-AUX is supplied with two galvanically isolated auxiliary voltages
V1 and V2 via the 7/8'' connector. This divides the IO-Link channels into two electrically isolated
potential groups C0…C3 (supplied from V1) and C4…C7 (supplied from V2).
The galvanic isolation of the potential group allows a safety shutdown of parts of an installation
via emergency-off circuits.
V1
Supply of connectors C0…C3 and the connected sensors and actuators

Connecting IO-Link
The device provides a 5-pin M12 connector for the connection to IO-Link and the supply
voltage.

Connect the device to IO-Link and the supply voltage according to the pin assignment
below.
1 = 24 VDC (VIOL)
2 = n.c.
3 = GND (V IOL)
4 = C/Q (IO-LINK)
5 = n.c.
