The Applications

1. Press Brake with Light Curtain & Emergency Stop

In heavy metalworking environments, press brakes pose significant risks due to moving rams. By connecting both a light curtain and an emergency stop into the safety relay, the system halts instantly when an operator’s hand enters the danger zone or when the stop button is pressed. The adjustable delay prevents false triggers while maintaining strict safety. Its dual-channel monitoring provides redundancy, ensuring that even if one input fails, protection remains active. This integration not only protects workers but also keeps production efficient, as the relay allows quick reset and reliable restart once conditions are safe.

2. Automated Packaging Line Door Protection

High-speed packaging systems often include robotic arms and palletisers that need controlled access. The safety relay monitors each door so that when an access point opens, all motion is immediately disabled. Depending on requirements, the relay can be set for manual or automatic reset, allowing tailored control for hygiene or operational needs. Its pluggable terminal design reduces wiring complexity, making replacement or maintenance faster. Compact housing ensures minimal space consumption in cabinets that already hold multiple controllers. By combining certified safety levels with simple operation, it guarantees both worker protection and continuous line productivity.

3. Conveyor Safety in Automotive Paint Shops

Automotive production uses long conveyor lines to transport vehicle bodies through paint booths and curing zones. During cleaning or maintenance, access gates must be monitored so machinery powers down immediately. The safety relay ensures motors and hazardous components stop as soon as a door opens. Adjustable delay functions provide time for fans or heaters to shut down in a controlled manner, protecting sensitive equipment. Its slim design helps in already crowded control cabinets, while long mechanical service life supports frequent use without degradation. This solution enhances worker safety while preserving critical uptime in demanding automotive environments.

4. CNC Machining Cell Dual Protection

CNC machining centers require layered safety because operators interact closely with cutting tools. A safety relay supervises both enclosure doors and emergency stop circuits, cutting power instantly if either is triggered. Force-guided contacts and fault detection ensure wiring issues or stuck relays are recognized, maintaining system integrity. The adjustable dropout time supports rapid machine stops, critical when handling rotating spindles at high speeds. This arrangement balances worker protection with production efficiency, allowing quick resets once safe conditions return. It is especially valuable in industries such as aerospace or precision mold making, where reliability and accuracy are essential.
