IO-LINK
IO-Link is the first globally standardized IO technology (IEC 61131-9) that communicates from the controller down to the lowest automation
level. This universally applicable interface is a fieldbus-neutral point-to-point connection which uses standard unshielded cables. IO-Link
sends all the sensor and actuator signals to the controller and in turn carries controller data to the sensor/actuator level with revolutionary
consequences.
It is possible to have IO-Link device of two different type: IO-Link Class A and IO-Link Class B. ADFweb.com’s converters can manage both
of them in relation to the product code selected.

A:
IO-Link Class A devices uses 4 pins on connectors and the input power required can be up to 200mA. These devices are normally sensors
and actuators that don’t require high input power.
