9.5 Connect Sensors/Actuators
The sensor/actuator cable provides power to the connected sensors/actuators and trans-
fers the sensor and actuator signals.
Note the current load capacity of the supply contacts; see “Rule 3” in

Rule 3: Ports X01, X02 etc
.
The following figure shows the potential routing of the two load circuits within the module.
If a port is operated in IO-Link mode, then at most 1 A can flow through pin 1 and pin 3
without additional measures. The use of standard cables allows lengths up to 20 m as
long as the current remains under 1 A.
Higher currents are possible and require a larger cable cross-section or shorter cable
length to keep the voltage drop for the outgoing and return paths below 1.2 V.
