The Pilz P2HZ X1 230VAC 3N/O 1N/C (part no. 774438) is a reliable and versatile safety relay developed to provide dependable monitoring of safety functions in industrial automation. As part of the Pilz P2HZ series, it combines robust performance, energy efficiency, and compliance with international safety standards, making it a trusted solution for safeguarding personnel and equipment.
Designed to operate on a 230 V AC supply, the P2HZ X1 integrates seamlessly into systems powered by standard industrial mains. This makes it suitable for widespread use in global applications, eliminating the need for additional voltage conversion hardware. Its 6 VA power consumption ensures energy-efficient performance, minimising both operational costs and heat generation within control cabinets.
The relay is equipped with a flexible contact arrangement consisting of 3 N/O enabling contacts and 1 N/C monitoring contact. The enabling contacts activate machine functions only when all safety conditions are met, while the monitoring contact allows for system feedback, diagnostic checks, or fault detection. This configuration supports robust system integration, enhancing both safety and transparency.
One of the defining features of the P2HZ X1 230VAC is its compatibility with two-hand control devices type III C. In such systems, the operator must press two separate buttons simultaneously to initiate machine functions, ensuring both hands are kept away from danger zones during hazardous operations. This is particularly critical in high-risk applications such as presses, stamping machinery, and other heavy-duty equipment where inadvertent activation could result in injury.
The device is built to withstand the demands of industrial environments. Its rugged construction ensures reliable performance under frequent actuation and continuous duty, while its straightforward wiring and clear terminal design simplify installation and reduce commissioning time.
As part of the Pilz safety ecosystem, the P2HZ X1 integrates smoothly with complementary products such as safety relays, guard door switches, and emergency stop devices. This compatibility allows engineers to build modular, scalable safety systems that comply with international standards including ISO 13849-1 and IEC 62061.
In practical applications, the P2HZ X1 is deployed across industries such as automotive manufacturing, packaging, material handling, and metalworking. It reliably monitors safety devices such as emergency stops, guard doors, and two-hand controls, ensuring that hazardous machine movements are immediately halted when unsafe conditions arise.
In summary, the Pilz P2HZ X1 230VAC 3N/O 1N/C is a robust and efficient safety relay designed to deliver reliable protection in industrial automation systems. With its 230 V AC operation, low power consumption, versatile contact configuration, and two-hand device compatibility, it provides engineers with a dependable solution for creating safe and standards-compliant machine architectures.
