The Applications of Phoenix Contact PSR-SCP-24UC/ESAM4/8X1/1X2 Safety Relay

1. Conveyor Systems – Safe Emergency Stops

On long conveyor lines used in logistics and packaging, safety relays like the PSR-SCP-24UC/ESAM4/8X1/1X2 allow multiple emergency-stop buttons to be connected along the belt. If an operator presses any button, the relay disconnects power within milliseconds, stopping motors before accidents occur. The eight enabling outputs provide redundancy for different motor sections, while force-guided contacts ensure the shutdown is fail-safe. This setup reduces the risk of entrapment and increases worker confidence when operating large automated transport systems.

2. Safety Mat Integration in Press and Molding Machines

In factories where operators work close to heavy presses or molding equipment, safety mats are installed at access zones. When someone steps onto the mat, the PSR-SCP relay detects the signal through dual channels and immediately halts machine movement. Its ability to detect wiring faults adds another layer of protection, ensuring the safety circuit cannot be bypassed. By supporting both automatic and manual reset options, the relay allows flexible operation while keeping operators safe during interventions or setup activities.

3. Safety Door and Gate Monitoring in Robotic Cells

Robotic cells often include protective doors or gates to separate people from moving machinery. The PSR-SCP safety relay connects to interlock switches, disabling power whenever a door is opened. Its quick response time minimizes hazards from unexpected entry into the work cell. The multiple safety outputs can control several actuators or contactors at once, giving engineers flexibility when designing safety systems. Thanks to its long mechanical service life, it performs reliably even with frequent door access in high-cycle manufacturing environments.

4. Light Curtain Monitoring in High-Speed Packaging

High-speed packaging machines use light curtains to detect intrusion into dangerous areas such as sealing jaws or cutting stations. The PSR-SCP relay evaluates these signals and cuts off power instantly if a beam is interrupted. Its dual-channel design ensures that even sensor faults or wiring errors are recognized and safely managed. Because of its fast switching time, the relay minimizes machine movement after a safety event, protecting workers while keeping overall production efficiency high in demanding packaging operations.
