In heavy industries such as metal forming or large presses, multiple motors and drives must stop at the same instant when an emergency stop is triggered. This relay’s eight enabling outputs allow coordinated shutdown across all drive circuits, preventing uneven braking that could damage equipment. Dual-channel monitoring ensures safety integrity even if one input fails, while the high SIL and PL ratings guarantee compliance with strict safety standards for critical production environments.
Automated packaging equipment relies on doors, covers, and safety curtains to protect operators from moving parts. When one of these is opened, the PSR-SPP relay reacts quickly to halt the process across multiple circuits. Its long service life makes it ideal for applications where guards are accessed frequently, and the signaling output provides feedback to monitoring systems, allowing operators to log and analyze shutdown events. This reduces downtime while maintaining a safe production line.
In robotic welding or assembly cells, operators may occasionally need to enter the workspace. The PSR-SPP relay provides a fail-safe shutdown by detecting unsafe conditions through dual-channel inputs from safety sensors. Its force-guided contacts prevent undetected faults and ensure that robots cannot restart until the system is manually reset. This combination of quick response and deliberate restart protects both operators and machines, making it a trusted safety layer in robotic automation.
Chemical and pharmaceutical facilities demand uncompromising safety for pumps, conveyors, and mixers handling hazardous materials. This relay enables multiple outputs to be switched off simultaneously, ensuring coordinated shutdown of interconnected systems. Its rugged design withstands continuous operation, while the signaling contact supports proactive maintenance by flagging potential issues before they compromise safety. With its wide operating temperature range, the relay remains dependable in harsh plant conditions, protecting both personnel and equipment.
