6.2.2 IO-Link circuits
11616
The IO-Link interfaces of the device meet the requirements of the IO-Link specification 1.0 to 1.1.2.
The connected IO-Link devices may only be supplied via the AL1122.
Exception: Connection of IO-Link devices to ports X01...X08 via suitable connection
technology for port class B operation (→ IO-Link ports (→ p. 19)):
The external supply for port class B operation must be galvanically separeted from the circuit
of the AL1122 by assuring basic isolation (according to EN61010-1, secondary circuit with
maximum 30 V DC derived from applied voltage up to 300 V of overvoltage category II)!
The isolation must be done both for IO-Link devices and for the connection technology.
Risk of material damage
If the requirements of galvanic separation of the circuits are not observed, the fire protection of the
device can not be assured.
► Observe the requirements of the electrical connection of IO-Link devices for port class B
operation!
