The Pilz PZE 9P C 24VACDC 8N/O 1N/C (Part No. 787140) is a powerful and flexible safety relay designed to provide dependable monitoring of safety functions in industrial automation environments. Part of the Pilz PZE series, this model offers high switching capacity and versatile supply options, making it an ideal solution for machine builders and plant operators seeking robust safety performance with integration flexibility.

One of the standout advantages of the PZE 9P C is its dual-voltage capability. It can operate on either 24 V AC or 24 V DC, making it compatible with both traditional and modern control infrastructures. This flexibility simplifies system design, reduces the need for additional converters, and allows the relay to be deployed across a wide variety of applications. With a low power consumption of 9.5 VA (AC) or 3.5 W (DC), it offers reliable performance while maintaining energy efficiency.

The relay is equipped with two inputs, enabling dual-channel monitoring for enhanced safety integrity. This redundancy ensures that safety devices such as emergency stop pushbuttons, guard doors, or enabling switches are monitored reliably. In the event of a fault or unsafe condition, the relay ensures immediate and safe disconnection of hazardous energy sources, protecting both operators and equipment.

A defining feature of the PZE 9P C is its extensive output configuration. With eight normally open (N/O) contacts and one normally closed (N/C) contact, it provides unmatched versatility in controlling multiple actuators, motors, contactors, and signal devices simultaneously. The large number of outputs allows it to serve as a central safety element in complex systems, where multiple machines or processes must be stopped safely and consistently. The N/C contact adds valuable functionality for status monitoring and feedback to supervisory control systems.

The robust design of the PZE 9P C ensures long service life, even under demanding industrial conditions. Engineered to meet international safety standards such as EN ISO 13849-1 and IEC 62061, it provides the reliability required for achieving up to Performance Level e or SIL certifications when integrated into appropriate safety circuits. Its compliance with these standards gives machine builders and operators confidence that their systems meet both operational safety and legal requirements.

Installation is made straightforward thanks to the relay’s clear terminal layout and compact design, which facilitate easy wiring and reduce commissioning time. Once in operation, the device requires minimal maintenance, helping to lower operational costs and maximise system uptime.

Applications for the PZE 9P C include manufacturing, packaging machinery, material handling systems, and process engineering plants, where multiple outputs need to be switched simultaneously in response to safety inputs. Its ability to handle both AC and DC supply voltages makes it especially valuable in environments with mixed power infrastructures.

In summary, the Pilz PZE 9P C 24VACDC 8N/O 1N/C combines dual supply flexibility, extensive output capacity, energy efficiency, and international safety compliance. It is a reliable, versatile, and future-proof solution for safeguarding industrial machinery while ensuring maximum system productivity and operator protection.
