The Pilz PNOZ 2 230VAC 3N/O 1N/C – 775850 is a robust safety relay designed to provide dependable monitoring of emergency stop devices, safety gates, and other protective equipment in industrial environments. As part of the trusted PNOZ range, this relay delivers secure switching, compliance with international safety standards, and straightforward integration into machine safety architectures.

Operating on a 230 V AC supply, the PNOZ 2 integrates seamlessly with standard industrial power infrastructures. Its stable operation at this common supply voltage makes it highly versatile and suitable for a wide range of automation and manufacturing applications. The relay’s 5 VA power consumption ensures efficient energy usage, reducing operational costs and minimising heat generation in control cabinets.

A key advantage of the PNOZ 2 is its output configuration, which includes three normally open (N/O) contacts and one normally closed (N/C) contact. The N/O contacts serve as enabling outputs, providing secure shutdown of actuators, motors, or contactors in response to a safety trigger. The N/C contact offers additional flexibility, such as feedback signalling or circuit monitoring, giving engineers more options when designing safety systems.

The relay is equipped with a single input channel, making it suitable for straightforward safety applications where monitoring a single protective device is sufficient. This configuration is ideal for installations where a simple yet effective safety solution is required, such as monitoring an emergency stop button or a safety gate. Despite its simplicity, the relay ensures reliable performance and compliance with relevant safety requirements.

Built in accordance with EN 60947-4-1, the PNOZ 2 complies with the utilisation category AC/DC1, guaranteeing its capability to switch safely and reliably under industrial load conditions. This compliance underscores the unit’s reliability in demanding applications and assures users of its long-term durability.

Compact and durable, the relay is optimised for control cabinet installation. Its clear terminal markings and simple wiring design allow for quick setup and integration. Once installed, it provides consistent safety functionality, even under continuous operation and frequent actuation cycles.

Typical applications for the PNOZ 2 include emergency stop monitoring, safety gate control, and protective cover supervision across industries such as packaging, processing, material handling, and assembly lines. Wherever operator protection and machine safety are essential, the relay provides dependable shutdown capability.

In summary, the Pilz PNOZ 2 230VAC 3N/O 1N/C – 775850 combines reliable AC operation, energy-efficient performance, and versatile outputs. Designed for straightforward safety applications, it delivers robust functionality and compliance with international standards, making it a practical choice for safeguarding machinery and ensuring operator protection.
