The Pilz PZE 9P C 24VACDC 24–240VACDC 8N/O 1N/C (part no. 787148) is a powerful and versatile safety relay developed for monitoring essential safety functions in industrial automation. As part of the Pilz PZE series, it combines a broad voltage range, extensive contact configuration, and high reliability to meet the diverse demands of machine and plant safety.

One of the defining advantages of this model is its wide supply voltage range of 24 to 240 V AC/DC. This flexibility allows engineers to integrate the device into systems across different regions and industries without the need for additional voltage adaptation. The inclusion of a 24 V DC auxiliary supply (U2) further enhances its versatility, providing a reliable interface for controllers and diagnostics.

The relay offers a comprehensive contact setup with eight normally open (N/O) enabling contacts and one normally closed (N/C) feedback contact. The enabling contacts provide redundancy and flexibility for controlling multiple actuators or safety outputs simultaneously, while the feedback contact facilitates monitoring and diagnostics. This configuration ensures safe interruption of hazardous movements and clear system visibility, both of which are critical in modern safety architectures.

Efficiency is a core feature of the PZE 9P C. With power consumption of just 9.5 VA in AC systems and 6 W in DC systems, it delivers reliable performance while minimising energy demand and thermal load in control panels. This makes it particularly suitable for continuous operation in high-duty-cycle environments where energy efficiency and system longevity are key considerations.

The device is built for industrial robustness, ensuring reliable operation in demanding applications such as automotive manufacturing, packaging, robotics, logistics, and heavy machinery. Its rugged design allows it to withstand frequent actuation, mechanical stress, and the environmental demands of industrial facilities.

As part of Pilz’s safety ecosystem, the PZE 9P C integrates seamlessly with other safety relays, controllers, and monitoring devices to form a complete safety chain. It complies with international safety standards such as ISO 13849-1 and IEC 62061, ensuring that users can achieve regulatory compliance and maximum operator protection.

Typical applications include monitoring emergency stop devices, guard doors, light curtains, enabling switches, and two-hand controls. In each case, the relay ensures immediate interruption of hazardous machine functions when unsafe conditions are detected, reducing the risk of injury and protecting both personnel and equipment.

In summary, the Pilz PZE 9P C 24VACDC 24–240VACDC 8N/O 1N/C is a highly flexible and efficient safety relay designed for demanding industrial environments. With its broad supply voltage range, extensive contact configuration, auxiliary supply support, and low power consumption, it provides a comprehensive and future-proof solution for safeguarding modern automation systems.
