The Pilz P2HZ X1 24VDC 3N/O 1N/C (Part No. 774340) is a specialised safety relay designed for reliable monitoring of two-hand control devices, ensuring operator safety in applications where hands must be kept clear of hazardous zones during machine operation. By requiring the simultaneous activation of two separate inputs, the relay guarantees that dangerous movements cannot be triggered accidentally or by improper operation.

Operating on a 24 V DC supply voltage and consuming just 2.5 W, the P2HZ X1 combines energy efficiency with robust performance, making it suitable for continuous operation in modern automation systems. The device is tailored for two-hand control systems classified under Type III C, the highest category according to EN 574. This classification ensures that the relay independently monitors both input channels, providing redundancy and fault detection to prevent unsafe conditions caused by wiring faults, short circuits, or component failures.

The relay features two independent inputs, which must be activated within a defined time window to initiate a machine command. This prevents operators from using one hand or bypassing the system, thereby ensuring compliance with stringent safety standards. The dual-channel monitoring further increases reliability by detecting discrepancies between the inputs, ensuring hazardous operations are disabled immediately in the event of a fault.

The output configuration includes 3 normally open (N/O) safety contacts, which provide robust disconnection of actuators, motors, or drives when unsafe conditions are detected. In addition, the relay offers 1 normally closed (N/C) auxiliary contact, which can be used for status monitoring or diagnostics, enabling clear communication to higher-level controllers or operator panels.

Engineered to comply with EN 60947-4-1 utilisation categories (AC/DC1) and related international standards, the P2HZ X1 provides long-lasting performance even in demanding industrial environments. Its compact design allows for easy integration into control cabinets, while clearly marked terminals simplify wiring and reduce commissioning time.

The Pilz P2HZ X1 is widely used in machinery where operator interaction with hazardous processes requires stringent safety measures. Typical applications include presses, cutting machines, stamping equipment, robotics, and assembly lines, where two-hand controls prevent accidental triggering of dangerous movements. By ensuring that both hands are engaged at the control station, the device effectively keeps operators away from danger zones, enhancing safety without compromising productivity.

In summary, the Pilz P2HZ X1 24VDC 3N/O 1N/C (774340) offers a dedicated two-hand control solution, combining efficient DC operation, dual-channel monitoring, robust output configuration, and compliance with the highest safety standards. It is a reliable and essential safety relay for industries that demand the highest level of operator protection in manual machine control applications.
