3. Product Overview
The IO-Link master establishes the connection between the IO-Link device and the
automation system. As an integral part of the I/O system, the IO-Link master station is
either installed in the control cabinet, or directly installed on site as a remote I/O, and
its encapsulation level is IP65/67.
❖Designed for industrial environments, it is a system applied to automated lines.
❖Compact structure, suitable for usage scenarios with limited installation conditions.
❖IP67 high protection level, anti-interference design, suitable for demanding application
environments.
As a special reminder, IP rating is not part of UL certification.

5. Product Installation
5.1 Installation Precautions
To prevent product malfunction, malfunction, or negative impact on
performance and equipment, please observe the following items.
5.1.1 Installation Site
Please avoid installing near devices with high heat dissipation
(heaters, transformers, large-capacity resistors, etc.)
Please avoid installing it near equipment with serious
electromagnetic
interference (large motors, transformers, transceivers,
frequency converters, switching power supplies, etc.).
This product uses PN communication.
Radio waves (noise) generated .
by transceivers, motors, inverters, switching power supplies, etc.
may affect the communication between the product and other
modules.
When these devices are around,
it may affect the communication between the product and the
module or damage the internal componentsof the module.
When using this product near these devices, please confirm the
effects before use.
When multiple modules are installed close to each other,
The service lifeof the modules may be shortened due to the inability
to dissipate heat.
Please keep more than 20mm between the modules.
5.1.2 Application
Do not use AC power. Otherwise, there is a risk of rupture, seriously
affecting the safety of personal and equipment.
Please avoid wrong wiring. Otherwise, there is a risk of rupture and
burnout. It may affect the safety of personal and equipment.
5.1.3 Usage
Do not bend the cable within a radius of 40mm. Otherwise there is
a risk of disconnection.
If you feel that the product is abnormal, please stop using it
immediately and contact the company after cutting off the power.
