The Pilz PNOZ X9 100-120VAC 24VDC 7N/O 2N/C 2SO – 774605 is a powerful and flexible safety relay designed to provide dependable monitoring of emergency stop functions, safety gates, and other protective devices. Belonging to the established PNOZ X series, it combines robust switching capacity, multiple output options, and international standards compliance, making it a trusted solution for safeguarding industrial machinery and operators.

Engineered for dual supply operation, the PNOZ X9 uses a 100–120 V AC primary supply and a 24 V DC secondary control voltage. This dual-voltage capability ensures adaptability in diverse automation environments, supporting integration into both traditional AC-driven systems and DC-based control architectures. To further enhance reliability, the unit accommodates an external DC voltage tolerance of -20 % to +20 %, ensuring stable performance even under fluctuating supply conditions.

One of the defining strengths of the PNOZ X9 is its comprehensive output configuration. The relay provides seven normally open (N/O) safety contacts for direct switching of actuators, motors, or contactors, ensuring immediate and safe shutdown during hazardous conditions. Additionally, it offers two normally closed (N/C) contacts for monitoring or feedback circuits, and two semiconductor outputs for fast, wear-free signalling to higher-level control systems. This broad range of outputs makes the relay suitable for complex safety architectures requiring both control and diagnostic functions.

With two dual-channel safety inputs, the PNOZ X9 supports redundancy and fault detection, significantly increasing system integrity. This ensures that faults such as wiring errors, short circuits, or contact failures are reliably detected, helping prevent unsafe conditions from going unnoticed. Its robust monitoring capability makes it ideal for safety-critical devices including emergency stop pushbuttons, protective doors, and safety light curtains.

The PNOZ X9 is built for durability and long service life in demanding industrial settings. Its compliance with EN 60947 safety standards guarantees reliable performance under continuous operation, frequent actuation, and challenging electrical environments. The unit’s compact yet rugged design allows for easy integration into control cabinets, supporting efficient installation and maintenance.

Typical application areas include automated production lines, packaging machinery, robotic cells, and process equipment—industries where operator safety and machine reliability must go hand in hand. The wide output range ensures it can support complex machine safety requirements while maintaining compliance with modern safety directives.

In summary, the Pilz PNOZ X9 100-120VAC 24VDC 7N/O 2N/C 2SO – 774605 offers extensive output capability, dual-supply flexibility, and reliable dual-input monitoring. With its robust design and compliance with safety standards, it delivers a dependable and versatile solution for safeguarding machinery and ensuring operator protection in industrial automation.
