- Dedicated Two-Hand Control Monitoring: Designed for two-hand control devices, Type III C, ensuring safe machine operation requiring both hands.
- Versatile Contact Configuration: Provides 3 normally open (N/O) safety contacts, 1 normally closed (N/C) auxiliary contact, and 2 signalling outputs (SO) for reliable control and feedback.
- Optimised for 230 V AC Supply: Operates with a 230 V AC supply voltage at 6 VA power consumption, suitable for standard industrial power systems.
- Built for Compliance and Safety: Engineered in line with international safety standards, ensuring robust fault detection and safe switching of hazardous energy.
The Pilz P2HZ X1P 230VAC 3N/O 1N/C 2SO, part number 777438, is a specialised safety relay from the trusted Pilz P2HZ series, developed to ensure the highest levels of operator protection by monitoring two-hand control devices (Type III C). It is particularly suited for machinery where both hands must be used to initiate a function, preventing accidental or one-handed activation that could lead to dangerous situations.
Operating on a 230 V AC supply with a modest 6 VA power consumption, the P2HZ X1P integrates seamlessly into standard industrial electrical systems. This makes it a practical choice for installations across global industries where 230 V AC is the common supply standard.
The relay’s contact configuration is designed to meet complex safety requirements. With 3 normally open (N/O) safety contacts, it ensures the reliable shutdown of hazardous machine movements by cutting off energy to actuators, motors, or other power-driven elements. The 1 normally closed (N/C) auxiliary contact provides valuable system feedback to control systems or operator panels, allowing real-time monitoring of the relay’s switching state. In addition, the inclusion of 2 signalling outputs (SO) offers diagnostic capability, enabling better system transparency and reducing troubleshooting time.
Central to its function is the Type III C two-hand control monitoring. This feature ensures that both hand-operated actuators must be pressed simultaneously within a specified timeframe for the machine to start or continue operating. If there is a delay between the two actuations, or if only one is pressed, the relay prevents operation. This design guarantees compliance with safety standards while protecting operators from inadvertent or unsafe machine activation.
The P2HZ X1P is built with durable electromechanical components, ensuring long service life and reliable switching performance, even under continuous use. Its robust construction allows it to operate effectively in demanding industrial environments, maintaining safety integrity despite mechanical stress or frequent switching cycles.
Applications for the P2HZ X1P are typically found in presses, stamping machines, cutting systems, and other equipment where enforced two-hand operation is essential. By integrating this relay, manufacturers can ensure compliance with international machinery safety standards, while safeguarding both operators and equipment.
In addition to safety, the relay supports ease of use. Its fixed wiring design and compact housing allow straightforward installation, while its signalling outputs enhance system diagnostics and maintenance efficiency.
In summary, the Pilz P2HZ X1P 230VAC 3N/O 1N/C 2SO (777438) is a powerful and reliable safety relay designed to monitor two-hand control devices with Type III C compliance. With its 230 V AC operation, versatile contact arrangement, integrated signalling outputs, and robust safety monitoring, it provides an effective solution for protecting operators and machinery in high-risk industrial environments.
