What is Pilz PNOZ s4 C Safety Relay 48–240VAC/DC (751134)

Pilz PNOZ s4 C Safety Relay 48–240VAC/DC (751134) is a configurable safety relay designed to monitor safety circuits such as emergency stops, safety gates, and interlocks across a wide voltage range. It provides reliable switching outputs to ensure safe machine shutdown when a fault or hazardous condition is detected.

This relay belongs to the PNOZsigma series, known for compact safety modules used in control panels where space and flexibility are important. The “C” variant typically supports extended input voltage ranges, making it suitable for installations where supply conditions vary between AC and DC systems.

It is commonly used in safety circuits that require redundancy monitoring and controlled restart logic. The relay evaluates input signals from devices such as emergency stop pushbuttons or guard switches and ensures that outputs respond only when safe operating conditions are met.

Unlike programmable safety controllers, this relay is designed for fixed safety logic, which simplifies integration in standard machine safety applications.

Applications of Pilz PNOZ s4 C Safety Relay 48–240VAC/DC (751134)

• Emergency Stop Circuits in Assembly Lines
Used to ensure immediate shutdown of conveyor systems or robotic stations when an operator activates an emergency stop.
• Safety Gate Monitoring in Packaging Equipment
Ensures machines stop when protective doors or guards are opened during operation.
• Textile Machinery Protection Systems
Monitors access points in high-speed looms where operator safety is critical.
• Material Handling Systems
Integrated into automated warehouses to prevent unintended motion during maintenance access.
• Machine Tool Safety Circuits
Used in CNC or cutting equipment to ensure safe stop during abnormal conditions.
• Food Processing Equipment
Supports hygienic environments where safety interlocks are essential for operator protection.
Each application benefits from the relay’s ability to operate across multiple voltage inputs without requiring separate variants.
