Ultra-Compact Safety Relays – Modular, Cost-Efficient, and Versatile

The ultra-compact MINOS series safety relays provide a state-of-the-art safety solution characterized by their space-saving design, flexible connection options, and maximum safety. With a width of only 6 mm, these relays are the perfect choice for applications where space in the control cabinet is limited. Their goal is to provide a modular and cost-efficient safety solution that focuses on the essentials without compromising on safety.

Two Versions for Flexible Requirements:

• MINOS SL Series: Equipped with wear-free, safe semiconductor outputs. This technology offers a long service life and is ideal for applications with frequent switching operations.
• MINOS SD Series: Features safe relay outputs with potential-free switching contacts. This version is especially suitable for applications requiring galvanic isolation of signals.

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

Efficient Diagnostics with Status and Error LEDs:

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

Space-Saving Design – Only 6 mm Wide:
With an ultra-slim design of only 6 mm, the relays save valuable space in the control cabinet. This compact design allows for high packing density, significantly reducing the space required in the control system.

Wide Range of Applications:

The MINOS series safety relays are versatile and ideally suited for:

• Monitoring Emergency Stop Buttons: Ensures the immediate shutdown of the machine in hazardous situations.
• Monitoring Safety Doors: Ensures that the machine operates only when the safety door is closed.
• Monitoring Light Curtains: Detects intrusion into the hazardous area and safely shuts down the machine.
• Reinforcement of Safe Outputs: Amplifies safe PLC outputs to control contactors or relays.

Certifications 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. Additionally, the modules meet the requirements of IEC 61511-1, qualifying them for use in the process industry. Thanks to these certifications, the relays are perfectly suited for safety-critical processes in the process industry, in machines and systems, as well as in combustion systems.
