Hydraulic presses pose high risk when operators work near moving platens. By wiring the PSR-MC30 safety relay to emergency stops and light curtains, the machine is forced to halt immediately if someone enters the danger zone. Dual-channel monitoring ensures both channels of the light curtain or stop button remain functional, while cross-circuit detection eliminates hidden wiring faults. The rapid switching time helps minimize damage and injuries. With this setup, press operators gain reliable safeguarding without slowing productivity, allowing heavy-duty forming operations to meet modern safety requirements.
Long conveyor systems in warehouses or packaging facilities require distributed protection. Multiple emergency stop switches and access gates can be linked into one PSR-MC30 relay, which instantly cuts power to conveyor motors when triggered. Having two enabling outputs allows safe control of different conveyor sections, reducing the chance of pile-ups or jams. Its slim 12.5 mm housing keeps control cabinets compact, even when many zones are covered. This approach prevents accidents like worker entanglement or collisions between products, while ensuring smooth restart procedures with monitored start functionality.
High-speed electronics assembly lines, such as SMT pick-and-place machines, need immediate response to protect technicians during setup or maintenance. When a safety door is opened, the PSR-MC30 interrupts motor power within milliseconds. Its dual-channel logic ensures redundancy, so a single wiring fault cannot compromise protection. The relay also requires a monitored reset, preventing unintended restarts before the area is secured. Compact dimensions allow it to fit easily into space-restricted panels inside production equipment. This provides reliable protection while maintaining the precision and uptime demanded by electronics manufacturers.
Industrial robots operate with speed and force that make guarding essential. The PSR-MC30 connects directly to interlocked gates, light sensors, or scanners, cutting robot drive power if a person enters the safeguarded zone. Its diagnostic output helps maintenance teams quickly identify the cause of a shutdown, reducing troubleshooting time. With robust insulation and tolerance for harsh environments, the relay functions dependably in automated welding, palletizing, or assembly cells. The combination of compact size, high safety certification, and fast reaction ensures operators are protected while robots perform at maximum efficiency.
