In automated packaging systems, operators must have an instant way to stop machinery in unsafe situations. The PSR-MC30 safety relay enables precise emergency-stop monitoring with two independent safety channels. When an E-stop is activated, power to critical components is immediately interrupted within milliseconds, reducing injury risks and equipment damage. Its compact width allows easy integration into tight control panels while maintaining full compliance with industrial safety standards.
In robotic production areas, access doors must be monitored to prevent entry during motion. The PSR-MC30 manages dual-channel safety door circuits, ensuring robots stop instantly when a door is opened. Force-guided relay contacts guarantee reliable disconnection of hazardous energy. The option for automatic or manual reset lets technicians safely restart equipment after inspection or maintenance, enhancing both productivity and operator protection in high-precision robotic environments.
Large conveyor systems often use safety mats to detect human presence in restricted zones. By pairing these mats with the PSR-MC30, systems gain fault detection for short or open circuits, ensuring genuine safety stops when someone steps on the mat. Its built-in diagnostic output sends clear status feedback to control units or indicator panels, helping maintenance teams quickly identify issues and keep production moving safely and efficiently.
Press and forming machines require both of an operator’s hands to activate controls simultaneously for safe operation. The PSR-MC30 enforces this logic through its two independent input channels, verifying that both start buttons are pressed at once before enabling motion. If either hand is removed, power is immediately cut off. Its durable relay design and short response time make it ideal for repetitive, high-risk applications where operator safety is the top priority.
