Safety relays / Safety controllers
They are a popular means of safe signal evaluation: safety relays and safety controllers monitor position switches, emergency stop devices or non-contact safety sensors to ensure the protection of people, machines and processes.
Whether as a classic variant or the smart way, for example as a programmable safety evaluation unit. As a space-saving or fully configurable module. We have the right solution for your business.
All data always in view: Safely monitor machines with safety relays
Our products can be used not only to monitor the reliability of the connected switches and sensors, but also to evaluate OSSD signals and diagnostic data, for example. Even switches and sensors connected in series are no problem for our safety controllers.
Our product range includes a large selection of devices for safe signal evaluation. In addition to classic safety relays and space-saving safety evaluators, fully programmable safety controllers are also available.
Safety relays and safety controllers are a crucial component of various industrial applications to ensure the safety of employees and machines alike. Their most important tasks include
- Monitoring the connected switches and sensors
- Emergency shutdown of machines and systems as soon as a hazard is detected or an emergency stop switch is actuated
- Opening safety doors only after the machine or system has come to a complete standstill
- Locking access points before the machine or system can be put into operation
- Fault diagnosis to identify potential sources of danger in advance (predictive maintenance)
BERNSTEIN AG offers various product variants for reliable signal evaluation. This enables us to cover all areas from small to very complex systems.

Expandable safety controller
The new SCx with many expansion options and DCD diagnostics for complex applications.
- Connectable devices:
up to 394 with DCD - Safety inputs:
up to 154 - Safety outputs:
up to 68 - Interfaces:
Profinet, Modbus/TCP, USB and EtherCAT - DCD-compatible
- Configurable via software
- Up to 8 I/O expansion modules
SCx
Expandable safety controller
The expandable SCx covers all the safety requirements of your machine. This is because up to 8 I/O expansion modules can be added, daisy chain diagnostics (DCD) can be used and data can be exchanged via three different fieldbus protocols.
In addition, this safety relay can also be integrated into our SMART Safety System for the complete protection of machines and systems.
SCR P
Programmable safety evaluation
The programmable safety relay is a smart alternative to the classic variants. Thanks to the wide range of application options, there is no need to purchase individual safety relay modules.
This not only saves you money, but also time, effort and space.

Programmable safety evaluation
Simple configuration via software
With our software specially developed for these safety evaluations, configuring the SCx or SCR P is quick and easy.
You can intuitively simulate your safety circuits using drag and drop and then test them in simulation mode.
