The IO-Link Safety System from Pilz consists of fully compatible components, which together form a seamless safety solution – from the controller to the sensor in the field.
All system components are designed to work together seamlessly, enabling simple integration and maximum transparency.
- Universal one-stop solution
- A strong partnership with exceptional expertise in IO-Link Safety
- Efficient implementation of your safety concepts
- Reliable functional safety
System Architecture of the IO-Link Safety System
In the IO-Link Safety System, all components communicate via a standardized interface:
- The IO-Link Safety Master connects the controller to the field level.
- The IO-Link Safety field devices supply safe signals and diagnostic data, while safeguarding access points and danger zones.
All communication is transparent and seamless.
The Result: A fully integrated system that makes planning, commissioning and operation significantly easier.
Are you planning an IO-Link Safety project? Pilz’s experts can help you choose the right components.

An Overview of the Components in the IO-Link Safety System
- IO-Link Safety Master: The first TÜV-certified IO-Link Safety Master PDP67 IOLS forms the interface to the safety controller and enables safe point-to-point communication up to field level.
- IO-Link Safety Control Unit: The control unit PITgatebox IOLS communicates directly with the IO-Link Safety Master and, in addition to supplying safe signals, also supplies status and diagnostic data in real-time.
- IO-Link Safety Light Curtain: The safety light curtain PSENopt II Advanced IOLS communicates directly with the IO-Link Safety Master and offers reliable access guarding.
The Master is used to connect IO-Link Safety devices such as the IO-Link Safety control unit and IO-Link Safety light curtains. The IO-Link Safety System uses 3-core, unshielded standard cable and up to 25 Bytes of data are transmitted in two directions, at up to 230.4 kbit/s. You will find this cable in the right lengths for your application in the Pilz portfolio. With the Pilz configuration tool you can configure and set parameters for the IO-Link Safety Master and devices.
Whether it’s safe operation, safety gate monitoring or electrosensitive protective equipment – the IO-Link Safety system from Pilz supports a diverse range of safety applications. The following examples provide an insight into typical application scenarios.

Practical Application Examples with IO-Link Safety
Packaging Plant with Access Guarding
IO-Link Safety Master + Safety Light Curtain + Safety Gate Guarding = Less wiring and faster installation
Decentralised IO-Link Safety Master PDP67 for integration of the safety light curtains PSENopt II Advanced IOLS and the safety gate solution PITgatebox with PSENmlock. The PITgatebox all-in-one solution combines an integrated E-STOP and operator keys in one device and also serves as an “IO-Link Safety hub” for safety sensors.
Benefits to you:
- Reduced wiring
- Space-saving field integration
- Rapid installation and commissioning
- Less susceptible to errors

Material Handling with Integrated Robotics
IO-Link Safety Master + Safety Light Curtain + Safety Gate Guarding = Rapid integration and transparent diagnostics
The IO-Link Safety Master PDP67 is used to integrate the safety light curtains PSENopt II Advanced IOLS with muting function and the safety gate solution PITgatebox with PSENmlock. The use of IO-Link Safety light curtains and next level muting enables higher plant availability.
Benefits to you:
- Rapid integration of all safety components
- Transparent diagnostics up to field level
- Reduced downtimes
- Basis for predictive maintenance
