On a metal-forming press line, operators must frequently access the tooling area for setup and maintenance. The PSR-SCP-24UC/ESM4/2X1/1X2 ensures that when a safety door opens, power to the press drive is cut instantly. Its dual-channel design monitors both interlock signals, so even if one circuit fails, the system still reacts. The result is reliable shutdown during unsafe conditions, preventing accidental machine cycling and protecting workers from serious hazards.
Robotic welding cells require fast safety responses when people enter the restricted zone. This safety relay integrates with light curtains or safety gates, monitoring redundant signals for maximum reliability. If a person steps into the work area, the relay disables robot motion within milliseconds. Its slim DIN rail housing makes it easy to fit in crowded cabinets, while its certified compliance gives engineers confidence in meeting strict global safety requirements.
High-speed packaging machines often combine two-hand controls with multiple emergency stop points. The PSR-SCP relay processes these inputs and ensures machinery halts whenever an unsafe action occurs. Its force-guided contacts prevent false restarts, while the redundant enabling paths deliver fail-safe operation. This simplifies wiring, enhances machine availability, and guarantees that workers remain safe while productivity is maintained across the line.
Material handling conveyors can pose risks when workers operate nearby. Safety mats around conveyor edges connect to the relay, which monitors dual signals for activation. Stepping on the mat immediately halts the conveyor and locks it until a reset is performed. The robust monitoring detects wiring faults as well, ensuring continuous reliability. By protecting staff near moving belts, the relay reduces accidents and downtime while keeping goods flowing efficiently.
