In stamping and press lines, heavy machinery creates serious risks whenever operators access the guarded area. By integrating the PSR-SPP-24DC/ESD/5X1/1X2/300 safety relay with door interlocks, machines are brought to a safe stop the moment a guard is opened. Its adjustable delay contacts allow tooling to decelerate safely, preventing both equipment stress and operator exposure. The dual-channel monitoring ensures that wiring faults or component failures are detected before restart, making the production line safer and more reliable under continuous operation.
Modern packaging machines rely on light curtains to protect workers while maintaining speed. The safety relay processes signals from the curtain and initiates an immediate stop if someone enters the hazardous zone. Its delay options help balance safety with productivity, allowing controlled stops when brief interruptions occur during material handling. Clear LED indicators simplify fault detection, so operators can resume work quickly after inspections. This creates a safer yet efficient packaging environment with minimal downtime.
Injection molding machines require precise safety measures to protect operators during cycle start. The PSR-SPP-24DC/ESD/5X1/1X2/300 enables two-hand control by checking that both control buttons are pressed simultaneously before motion begins. If one channel fails or is pressed out of sync, the relay prevents activation and safely halts the machine. The force-guided contacts add redundancy, ensuring dependable switching. This design keeps operators safe while preserving machine efficiency and production throughput.
CNC machining centers often enclose cutting areas with safety doors. The relay works with these door interlocks, cutting power instantly when access is attempted mid-cycle. Its configurable delay range supports controlled spindle rundown or tool withdrawal before full stop, reducing wear while maintaining operator safety. The unit’s robust design and simple reset options allow integration in both new installations and retrofits. This makes it a trusted choice for machine builders seeking consistent compliance with modern safety standards.
