Pilz PNOZ s5 Safety Relay 750135, 240V AC/DC & 48V AC/DC, 2 Safety Contacts, DIN Rail, IP54

The Pilz PNOZ s5 Safety Relay, model 750135, is a high-reliability relay module engineered for machine and process safety functions in industrial automation settings. Designed to handle 240V AC/DC and 48V AC/DC coil voltages, this dual-voltage capability provides flexibility for integration into diverse electrical panels and systems requiring safe switching operations.

This safety relay offers two normally open (NO) safety contacts, creating a redundant and reliable switching path essential for critical safety circuits. Its compact DIN rail enclosure, measuring just 102mm in length, 120mm in height, and 22.5mm in width, allows for efficient space utilization in control cabinets and complex automation setups.

Engineered to withstand the rigors of industrial environments, the relay features an IP54 rating, effectively protecting internal components against dust and splashing water. The device is operable within a wide range of ambient temperatures, from -10°C to 55°C, making it suitable for a variety of demanding factory and process applications.

The terminal block uses screw connections, ensuring durable and secure wiring over the lifetime of the installation. The product’s compliance with rigorous international standards - EN 60947-5-1, EN 60204-1, and VDE 0113-1 - demonstrates suitability for safety-critical applications across manufacturing, machinery, conveyor systems, and process automation.

The Pilz PNOZ s5, Series Sigma 5, eliminates the need for separate relays for different supply voltages by supporting both 240V and 48V operation. Its two safety channels can be used to directly control actuators or interface with more complex safety controllers. The relay's compact footprint suits installations where panel space is at a premium or where multiple relays must be grouped.

This specific safety relay is used widely in emergency stop circuits, safety gates, and light curtain monitoring where reliable, fail-safe disconnection is required as part of a comprehensive safety control strategy. Its standard compliance and robust build make it a favored choice for original equipment manufacturers (OEMs), industrial control integrators, and maintenance engineers.

Typical application sectors include manufacturing plants, automation and assembly lines, machine building, processing facilities, and advanced industrial control systems. The device's design ensures ongoing protection and code compliance while enabling straightforward maintenance and replacement.
