Port class A (type A)
The IO-Link port according to type A is assigned an additional hardwired DI (digital input) at pin 2�
Port class B (type B)
The IO-Link port according to type B has an additional supply voltage via pins 2 and 5� This port is
suitable for connecting devices that have a higher current consumption�
Operating modes
The C/Q cable (pin 4) can be configured independently of the other pins� The IO-Link ports can be
operated in the following operating modes:
– DI (behaves like a digital input supplied via U
S
)
– DO (behaves like a digital output supplied via U
S
)
– IO-Link (IOL sensor supplied via US / IOL actuator supplied via U
S
and U
A
)
