Effective safety modules for comprehensive machine protection
What are safety modules?
Safety modules are special electrical devices used in automated systems to ensure the safety of people and machines. They serve to detect dangerous conditions and take appropriate measures to prevent accidents or injuries. If a component inside fails or a contact welds shut, the device immediately detects this defect and prevents the machine from restarting.
What are the features and functions of safety modules?
- Monitoring of safety functions: They monitor safety-related functions, such as emergency stop switches, door switches, or light barriers, to ensure that machines are shut down immediately in an emergency.
- Fast response times: Safety switching devices are designed to respond quickly to dangerous situations in order to minimize the risk of injury.
- Redundancy: Many safety switching devices have redundant systems to increase reliability. This means that they continue to function even if part of the system fails.
- Compliance with standards: Safety switching devices must comply with certain safety standards and norms, such as ISO 13849 or IEC 62061, to ensure that they can be used safely in industrial applications.
- Easy integration: They can be integrated into existing automation systems and can often be combined with other safety components.
- Central interface: Acts as a secure link between the sensor (input) and actuator (output) levels.
What are the areas of application for safety modules?
- Manufacturing industry and mechanical engineering: These devices are located on stationary production machines, where they immediately stop dangerous work movements such as pressing, drilling, or cutting as soon as an operator intervenes or a protective device is breached.
- Robotics and handling technology: In this area, they secure the radius of action of industrial robots by ensuring that the machine stops immediately or switches to a safe mode when a person approaches the work area or a protective door opens.
- Conveyor and storage technology: Here, they are used along extensive transport routes and in automated warehouses to safely and synchronously shut down drive motors over long distances in the event of malfunctions or emergencies.
- Process and heavy industry: In this environment, they are used to monitor mechanical locks on containers, mixers, or shredders so that the system can only start up when the lids are securely locked, preventing accidents caused by rotating parts.

Our portfolio:
Our safety relays were developed to monitor sensors such as safety sensors and light curtains, including their wiring, in order to immediately stop the moving parts of machines in the event of danger. By using safe coupling relays, the safety relays can be easily extended with additional, safe relay outputs.
This enables flexible adaptation to different industrial requirements.
If a safe output with a precise delay is required, our SCB is the ideal safety module. The SCB is a universally applicable, safety timer that enables delays of up to 99 hours. This makes it ideal for applications where a delayed switch-off is required.
For larger machines in which a single emergency stop relay is no longer sufficient, our innovative TALOS® safety controller is used. This compact safety module combines the advantages of individual safety devices in one device. Thanks to the built-in display, users can choose from a variety of configurations, allowing functions to be parameterized and delay times to be set individually.
Our comprehensive range of safety solutions has been developed to meet the diverse requirements of modern industrial environments while complying with the highest safety standards.
