NOTE
Power load greater than 16 A
Damage to the device
4
Ensure that the maximum permissible total current (for the whole terminal) of 16 A is
not exceeded.

In addition, suitable fuse protection of the supply line is necessary.

The supply line must be designed in accordance with the planned power consumption
and the length of the line. A cable cross-section of 2.5 mm² is recommended.
If communication of the higher-level bus system (Profinet, Ethernet/IP, EtherCAT) is inter-
rupted, the output process data of the IO-Link masters (IO-Link output) are reset to 0 (zero) for
safety reasons.
3.4.1 Description
The IOL master is a decentralized IO-Link, input and output module. It enables the connection of up to
four IO-Link devices. These can be actuators, sensors, or a combination of both.
Two LEDs are assigned to each IO-Link master port. The LEDs indicate the communication status and the
actuator supply voltage.
Up to four IO-Link devices (with the possible transmission speeds COM1, COM2, COM3) can be connected
to each IO-Link master. All communication takes place via the industrial Ethernet interface. All master
ports are designed as Class B ports and marked accordingly. This allows sensor-actuator systems to be op-
erated while taking electrical isolation into account. IO-Link class A devices can also be connected using a
3-pole sensor connection line. Up to 2 A per port from the actuator supply voltage are available for the
actuators. If the actuator current is exceeded, the corresponding port is switched off.
The maximum permissible total current of 16 A (of the whole terminal) must not be exceeded. The power
consumption of other components within the whole terminal must also be taken into account --> see 4.2
“Electrical and Technical Parameters”.
The pin assignment corresponds to the IO-Link specification for class B ports. See also chapter 8.4.3.
The IO-Link ports of the device satisfy the requirements of the IO-Link specification 1.1.
Max. line length per IO-Link port: 20 m.
