The Pilz P2HZ X1 115VAC 3N/O 1N/C (part no. 774435) is a dependable safety relay engineered to monitor and control safety-critical functions in industrial automation systems. Part of Pilz’s trusted P2HZ series, this relay combines robust functionality, flexible contact configuration, and compliance with safety standards to ensure reliable operator and machine protection.
Designed for a 115 V AC supply voltage, the relay integrates easily into a wide range of low-voltage safety circuits. Its modest power consumption of 6 VA ensures energy-efficient operation, supporting long-term use while minimising heat build-up in control cabinets. This balance of reliability and efficiency makes it ideal for continuous industrial duty.
The device is equipped with a versatile contact arrangement, consisting of 3 N/O enabling contacts and 1 N/C monitoring contact. The N/O contacts ensure that machine functions can only proceed when all monitored safety conditions are satisfied, while the N/C contact provides circuit feedback or fault monitoring, improving system transparency. This flexible design allows engineers to configure the relay for a variety of safety applications.
A notable strength of the P2HZ X1 115VAC is its compatibility with two-hand control devices of type III C. This feature ensures that hazardous machine functions require simultaneous operation of two separate controls, keeping the operator’s hands safely away from danger zones. This function is particularly critical in applications such as presses, stamping machinery, or other equipment where accidental activation could result in injury.
Engineered for long service life and industrial resilience, the relay is designed to withstand demanding conditions, including frequent actuation cycles and exposure to electrical noise. Its durable build ensures consistent performance and reduced downtime, while its compact format supports efficient installation in space-limited control panels.
Integration is straightforward, with clear terminal markings and wiring design that simplify commissioning and reduce installation errors. The relay’s proven Pilz design ensures seamless compatibility with other Pilz safety products, including emergency stop pushbuttons, safety gate switches, and evaluation devices. Together, these components form a complete, standards-compliant safeguarding system that meets international requirements such as ISO 13849-1 and IEC 62061.
In practical use, the P2HZ X1 115VAC is highly versatile. It can be applied to monitor emergency stops, guard doors, safety gates, light curtains, and two-hand control devices, making it an essential element in the protection of operators and machinery. Its reliable performance ensures peace of mind in industries such as automotive, packaging, metalworking, and material handling.
In summary, the Pilz P2HZ X1 115VAC 3N/O 1N/C safety relay is a robust and flexible solution for safeguarding industrial applications. With its 115 V AC operation, efficient 6 VA consumption, adaptable contact configuration, and compatibility with type III C two-hand control systems, it offers engineers a dependable foundation for building safe, standards-compliant automation systems.
