6.4.1
Input circuit
17863
The inputs of the ports X01...X08 (clamp 2) are of type 2 according to the standard EN61131-2, the
connected electronics must be designed for this purpose.
>
6.4.2
IO-Link circuits
7260
The IO-Link ports of the device meet the requirements of the IO-Link specification 1.0 bis 1.1.2.
The power supply of the connected IO-Link devices may only take place via the AL1900.
Exception: Connection of IO-Link devices with additonal external power supply to ports
X01...X08 for port class B operation
Wiring:
Maximum admissible current for UA: 4 A
The external supply for port class B operation must be galvanically separeted from the circuit
of the AL1900 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)!
NOTICE
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!
