Ultra-Compact Safety Relays – Modular and Cost-Efficient Safety Solutions

The ultra-compact MINOS series safety relays provide an innovative safety solution with minimal space requirements. With a width of only 6 mm, these relays combine the highest safety standards, simple diagnostic functions, and flexible connection options. The main goal of these relays is to provide a modular, cost-efficient safety solution that focuses on the essentials – without compromising on safety.

Two Versions for Maximum Flexibility:

• MINOS SL Series: Equipped with wear-free, safe semiconductor outputs. This technology ensures a particularly long service life and is ideal for applications with frequent switching operations.
• MINOS SD Series: Features safe relay outputs that provide potential-free switching contacts. This version is ideal when galvanic isolation of signals is required.

Both series meet the highest safety requirements up to PL e / Cat. 4 / SIL 3, making them the ideal solution for safety-critical applications in industry.

Excellent Diagnostic Functions:

The MINOS series safety relays are equipped with status and error LEDs that indicate the operating status and potential faults. This facilitates maintenance, reduces downtime, and allows for fast troubleshooting.

Space-Saving Design – Ultra-Slim with Only 6 mm Width:
With their ultra-compact design of only 6 mm in width, the relays save valuable space in the control cabinet. This space-saving design allows for higher packing density and reduces installation costs.

Versatile Applications:

The MINOS series safety relays are suitable for numerous safety-critical applications in industry. Typical areas of application include:

• Monitoring Emergency Stop Buttons: Ensures fast and safe shutdown of the machine when the emergency stop button is pressed.
• Monitoring Safety Doors: Ensures that the machine can only be operated when the safety door is closed.
• Monitoring Light Curtains: Detects the intrusion of people or objects into the hazardous area and safely shuts down the machine.
• Reinforcement of Safe Outputs: Amplifies safe PLC outputs to control downstream contactors or relays.

Certified for Demanding Areas of Use:

The MINOS series safety relays are certified for continuous operation in combustion systems according to EN 50156-1 and EN 746-2. In addition, the modules meet the requirements of IEC 61511-1, making them suitable for use in the process industry. These certifications ensure that the relays are suitable for use in safety-critical processes in machinery, systems, and combustion systems.
