The Pilz PNOZ X3 115VAC 24VDC 3N/O 1N/C 1SO (Part No. 774315) is a high-performance safety relay engineered to monitor essential safety functions and reliably disconnect hazardous machine operations when unsafe conditions are detected. Part of the renowned PNOZ X series, this relay combines robust safety performance with flexible output configuration, making it a versatile choice for industrial safety applications.

Powered by a 115 V AC supply (U1), with an additional 24 V DC auxiliary supply (U2), the PNOZ X3 ensures compatibility across a wide range of control system architectures. This dual supply design allows the relay to support both traditional AC-driven systems and modern DC-based safety logic, offering greater integration flexibility. With a power consumption of only 5 VA, it is efficient for continuous operation, reducing energy demand and heat build-up inside control cabinets.

The device features two inputs, enabling dual-channel monitoring of critical safety devices. This redundancy ensures that faults such as wiring errors, cross faults, or component failures are quickly detected and managed, preventing unsafe conditions. Safety devices typically connected include emergency stop buttons, light curtains, guard door switches, enabling devices, and two-hand controls.

On the output side, the PNOZ X3 is equipped with a comprehensive configuration: 3 normally open (N/O) safety contacts provide reliable disconnection of actuators, drives, or contactors, while 1 normally closed (N/C) auxiliary contact supports signalling and system feedback. Additionally, the relay includes 1 semiconductor output (SO), offering fast-response and wear-free signalling for diagnostics or communication with higher-level controllers. This combination allows the PNOZ X3 to provide both robust safety switching and efficient system transparency.

The device is engineered to comply with EN 60947-4-1 utilisation categories (AC/DC1), ensuring long-lasting reliability even under heavy-duty switching conditions. With its durable build and industrial-grade design, the relay can withstand the demands of modern automated systems while maintaining consistent safety performance.

The compact housing and clear terminal assignments make installation straightforward, reducing wiring complexity and commissioning times. Maintenance is also simplified by the integrated LED indicators, which provide at-a-glance status information, allowing operators and technicians to quickly identify power, input, and output states.

Applications for the PNOZ X3 115VAC 24VDC span a wide variety of industries, including automotive, packaging, robotics, material handling, and process automation. Its ability to handle multiple outputs, combined with dual-channel safety monitoring and diagnostic signalling, makes it particularly suitable for complex machinery where high reliability and flexibility are essential.

In summary, the Pilz PNOZ X3 115VAC 24VDC 3N/O 1N/C 1SO (774315) offers dual supply capability, versatile output configuration, dual-channel safety monitoring, and efficient performance. It is a reliable, standards-compliant safety relay designed to protect operators and equipment while ensuring smooth integration into modern industrial environments.
