The Applications

1. Automated Packaging Lines in Food & Beverage Industry

Modern packaging machines operate at high speed and require dependable safety measures. This extension module supports safety doors, emergency stops, and light curtains by ensuring all motion stops immediately when a hazard is detected. With multiple output paths and an adjustable shutdown delay, conveyors and cutting units can be powered down in a controlled order. This prevents leftover motion or material jams while protecting operators working near the machines. The compact size makes it easy to install in crowded control panels often found in food and beverage production environments.

2. Robotic Welding Cells in Automotive Manufacturing

Robotic welding stations demand strict safety control due to moving arms and intense welding arcs. The safety relay extension module links multiple interlock switches and gates, ensuring the robot halts when someone enters the area. Certified to top safety categories, it provides reassurance for compliance and audits. Its long mechanical lifespan supports constant switching cycles typical in automotive production. Adjustable off-delay allows robot arms to return to a neutral position and ensures weld arcs cool before the system fully shuts down, minimizing risks while keeping productivity intact.

3. Press Brakes and Metal Forming Machinery

Press brakes and forming machines rely on precise safety control due to their immense mechanical force. The extension module monitors emergency stop buttons and two-hand operation devices, enabling a safe stopping process. Its confirmation path ensures that contacts open as expected, reducing the chance of unnoticed failures. Adjustable timing helps absorb rebound from hydraulic systems, protecting both operators and the machinery itself. The force-guided contact design makes malfunctions easier to detect, providing confidence for users who need reliable, uninterrupted safety performance in heavy-duty manufacturing tasks.

4. Chemical Process Plants – Pump and Valve Safety Shutdowns

In chemical environments, pumps and valves must be shut down carefully to avoid pressure surges or leaks. The safety relay extension module receives signals from temperature detectors, interlocks, and flow sensors to manage shutdown in a sequence that protects sensitive equipment. Its adjustable off-delay ensures pumps wind down before valves close, reducing the chance of damage or sudden pressure spikes. Built for industrial use, it operates reliably even in demanding conditions such as humidity or corrosive atmospheres, making it a dependable choice for ensuring safe handling of chemical processes.
