In modern manufacturing cells, operators often work near CNC machines and automated equipment with multiple access doors. The PSR-SPP-24DC/SIM4 enables several door switches to be connected to a single safety relay. Each input channel has a clear LED indicator, making it simple to locate which guard is open or malfunctioning. The compact housing saves control cabinet space, while Push-in terminals reduce wiring errors during installation. By consolidating safety circuits in this way, manufacturers ensure rapid machine shutdown in unsafe situations while maintaining efficient operations.
High-speed packaging lines rely on safety interlocks to protect workers around conveyors, sealing machines, and robotic arms. The PSR-SPP-24DC/SIM4 provides a central interface to manage multiple interlocks at once. Diagnostic outputs allow controllers to track each switch’s condition, helping prevent unexpected downtime. Operators can see instantly which panel has been opened thanks to status LEDs. With safety compliance up to Cat. 3 / PL d, it creates a dependable safeguard for complex packaging systems. This balance of protection and system transparency improves both worker safety and production reliability.
Robotic cells in automotive assembly plants use a combination of light curtains, guard doors, and emergency stops to protect personnel. The PSR-SPP-24DC/SIM4 brings together up to four two-channel devices in one module. Flexible compatibility with both normally open and normally closed contacts makes it suitable for mixed sensor types. The integrated diagnostic outputs provide feedback to higher-level systems, giving maintenance teams insight into sensor health before problems escalate. With LED signaling for each input, faults can be pinpointed quickly, reducing downtime and keeping assembly lines running safely and efficiently.
Food processing plants require reliable safety systems on doors and covers surrounding cutting, filling, or packaging machinery. The PSR-SPP-24DC/SIM4 handles multiple interlocks in a single unit, reducing wiring complexity in areas where frequent cleaning and maintenance occur. Its wide temperature range allows use near cold storage zones without compromising performance. When an access point is opened, the connected relay immediately shuts down the equipment, ensuring operator safety. Status signals and diagnostic feedback help maintenance teams identify the specific interlock engaged, minimizing production delays and supporting strict hygiene and safety protocols.
