The Pilz PNOZ 1 24VAC 3N/O 1N/C (Part No. 775600) is a compact and reliable safety relay from the industry-leading PNOZ series, designed to supervise safety functions and guarantee secure disconnection of hazardous energy sources. Built to meet stringent international standards, it offers dependable protection for operators and machinery in a wide range of industrial environments.

Powered by a 24 V AC supply voltage, the PNOZ 1 ensures compatibility with AC-based control systems. Its dual-channel monitoring capability with 2 inputs provides redundancy and fault detection, guaranteeing that wiring errors, cross faults, or component failures are quickly identified. This ensures that the safety system performs reliably under all conditions, preventing unsafe machine operation and supporting compliance with standards such as EN ISO 13849-1 (PL e) and IEC 62061 (SIL 3).

The relay features a versatile contact configuration consisting of 3 normally open (N/O) safety contacts and 1 normally closed (N/C) auxiliary contact. The N/O contacts enable secure disconnection of actuators, motors, or drives, ensuring hazardous functions are stopped immediately when triggered by connected safety devices. Meanwhile, the N/C auxiliary contact provides valuable feedback for diagnostics or higher-level control systems, improving transparency and supporting predictive maintenance.

With its high switching capacity, the PNOZ 1 is rated for 240 V AC at 8 A, as well as 24 V DC, making it suitable for handling both AC and DC safety loads. This versatility ensures reliable protection for a wide range of machinery, from presses and robotic systems to conveyors and packaging lines. Compliance with EN 60947-4-1 utilisation categories (AC/DC1) further guarantees dependable performance under industrial load conditions.

The compact housing and simple wiring layout of the relay make installation and integration straightforward. Its clearly labelled terminals minimise the risk of wiring errors and reduce commissioning times, while its robust design ensures long-term durability even in demanding operating conditions.

Applications for the PNOZ 1 24VAC are diverse, covering industries such as automotive, packaging, process automation, robotics, pharmaceuticals, and material handling. It is particularly effective in small to medium-sized machines requiring simple, reliable, and standards-compliant safety monitoring without unnecessary complexity.

In summary, the Pilz PNOZ 1 24VAC 3N/O 1N/C (775600) combines efficient AC operation, dual-channel input monitoring, flexible contact configuration, and high switching capacity. As part of the trusted PNOZ family, it delivers dependable performance and ensures compliance with international safety standards, making it a valuable solution for safeguarding machinery and operators in industrial automation.
