TBPN-L1-FDIO1-2IOL - Standard IO-Link
2.2 Power supply of the IO-Link ports
2.2.1 Class A/B supply
Class A supply: pin 1 and pin 3,
Class B supply: pin 2 and pin 5
see also Connecting (page 31)
NOTE
The two supply voltages are not galvanically isolated.
NOTE
Set the respective output (DXP 13 or DXP 15) in the process output data in order to acti-
vate the Class B supply, see Process Output Data – IO-Link Master Channels (page 13).
2.2.2 Safe shutdown of IOL2 (at C7)
The IO-Link port at C7 is supplied via the internal safe output FSO 1.
This allows a safety-related shutdown of the port.
IO-Link port Connector Power supply
IOL1 C6 Vaux1
IOL2 C7 FSO 1 (clocked by test pulses)
NOTE
The IO-Link port at C7 is supplied via the internal safe output FSO 1.
Connected IO-Link devices must have a respectively high capacitance in order to tolerate
the test pulses of the safety output.
