The Pilz PNOZ X2P 24VAC/DC 2N/O (Part No. 777303) is a compact, efficient, and highly reliable safety relay designed to monitor safety functions and provide secure disconnection of hazardous movements in machinery. Belonging to the widely trusted PNOZ X series, it delivers a balance of simplicity, flexibility, and robust performance, making it suitable for a broad range of industrial safety applications.
One of its key advantages is its dual supply capability, supporting both 24 V AC and 24 V DC operation. This versatility makes it easy to integrate into existing control systems regardless of their power supply standard. With a low power consumption of 4.5 VA (AC) or 2 W (DC), the PNOZ X2P ensures energy efficiency in continuous operation, minimising both energy costs and heat generation within control panels.
The device features two input channels, enabling dual-channel monitoring of safety devices. This redundancy ensures that wiring faults, cross faults, or component failures are reliably detected, preventing unsafe restarts and ensuring compliance with international safety requirements. Typical safety devices connected include emergency stop pushbuttons, guard door interlocks, enabling switches, and light curtains. By supervising these devices, the relay guarantees that hazardous machine functions are safely brought to a halt when triggered.
On the output side, the PNOZ X2P is equipped with two normally open (N/O) safety contacts, which can be used to safely disconnect actuators, drives, or motors. These outputs ensure reliable switching capacity for industrial loads up to the utilisation category defined in EN 60947-4-1 (AC/DC1), supporting switching of resistive or slightly inductive loads with a rated voltage up to 240 V AC. This ensures robust and dependable performance in a wide variety of applications.
The compact form factor of the relay makes it easy to install in control cabinets where space may be limited. Its clearly labelled terminals simplify wiring and reduce commissioning times, while the robust mechanical and electrical design ensures long service life even in demanding environments subject to vibration or frequent switching cycles.
Applications for the PNOZ X2P span across industries such as automotive manufacturing, packaging, robotics, process automation, and general machinery, where operator protection and machine safety are critical. It is particularly well-suited for small to medium-scale safety functions where reliable dual-channel monitoring and straightforward output switching are required.
In summary, the Pilz PNOZ X2P 24VAC/DC 2N/O (777303) delivers dual power supply compatibility, low-energy performance, dual-channel input monitoring, and reliable output switching capacity. It is a versatile and compact safety relay that ensures compliance with international safety standards while providing a dependable safeguard for operators and machinery in industrial automation.
