The PILZ PNOZ X2.1 is a compact, standalone safety relay designed for monitoring safety circuits in industrial automation systems, particularly where protection of personnel and machinery is critical.

Overview

The PNOZ X2.1 provides a safety-related interruption of electrical circuits, ensuring that hazardous machine movements are stopped immediately when a fault or emergency condition occurs. It complies with major safety standards such as EN 60947-5-1 and EN 60204-1, making it suitable for safety-critical applications.

Key Features

• Dual-channel or single-channel inputs for flexible wiring of safety devices
• 2 normally open (N/O) safety contacts with positive-guided relays
• Redundant internal design with self-monitoring, ensuring high reliability
• Automatic or manual reset/start function
• LED indicators for power and channel status
• 24 V AC/DC supply voltage
• Slim 22.5 mm DIN-rail mounting housing

Functionality

The relay monitors input devices such as emergency stop buttons or safety switches. When the input circuit is closed (safe condition), the relay energizes and closes its safety contacts. If a fault occurs—such as an emergency stop activation—the relay opens the contacts immediately, cutting power to the machine.

The device also performs automatic internal checks during each switching cycle, verifying that the safety contacts open and close correctly.

Typical Applications

• Emergency stop (E-STOP) circuits
• Safety gate or guard monitoring
• Limit switch monitoring
• Machine interlocking systems

Safety Performance

The PNOZ X2.1 is designed for high safety integrity, supporting applications up to:

• Performance Level (PL) e (ISO 13849-1)
• Safety Integrity Level (SIL) 3 (IEC 61508)

Summary

The PILZ PNOZ X2.1 is a reliable and widely used safety relay that ensures safe shutdown of machinery by continuously monitoring safety inputs and providing redundant, fail-safe outputs. Its compact size, flexible configuration, and high safety ratings make it suitable for a wide range of industrial safety applications.
