The Pilz PNOZ X4 115VAC 3N/O 1N/C (Part Number: 774735) is a high-quality safety relay developed to monitor essential safety functions such as emergency stop buttons, safety gates, and two-hand controls. As part of the widely trusted PNOZ X series, this relay combines robustness, simplicity, and compliance with international standards to ensure both personnel and machinery remain safe during operation.

Designed to operate at a supply voltage of 115 V AC, the relay integrates easily into control systems powered by standard industrial AC networks. With a power consumption of just 5 VA, it delivers efficient performance while maintaining reliable safety monitoring, making it a cost-effective choice for both OEMs and system integrators.

The dual input channels allow the relay to monitor multiple safety devices simultaneously. This flexibility makes it well-suited for installations where redundancy and layered protection are required. For example, it can monitor both an emergency stop circuit and a safety gate switch, ensuring that hazardous movements are halted immediately when either input is triggered.

The output configuration includes 3 normally open (N/O) safety contacts and 1 normally closed (N/C) auxiliary contact. The N/O contacts provide multiple switching paths for isolating hazardous energy sources, such as motors, actuators, or power supplies. The N/C auxiliary contact is ideal for diagnostic or signalling purposes, giving operators and higher-level controllers immediate feedback on the relay’s status.

Compliant with the utilisation category AC/DC-1 (EN 60947-4-1), the relay is engineered to meet international safety and performance standards. This guarantees safe and consistent operation across a wide range of industrial applications, including automotive production, packaging systems, robotics, logistics, process automation, and heavy machinery environments.

The PNOZ X4 is known for its rugged construction and long service life, even under continuous operation in demanding conditions. Its straightforward wiring and compact design make it simple to integrate into existing safety architectures, reducing both commissioning time and long-term maintenance costs.

In practice, the PNOZ X4 115VAC 3N/O 1N/C is used in any application where immediate and reliable disconnection of hazardous energy is critical. Whether monitoring a single E-stop device or forming part of a larger safety chain, it ensures that operators are protected and that machine safety standards are consistently upheld.

In summary, the Pilz PNOZ X4 115VAC 3N/O 1N/C (774735) is a robust and flexible safety relay, offering reliable AC operation, multiple outputs, and compliance with international standards. With its dual input channels, efficient power consumption, and durable design, it provides an essential safeguard for a wide range of industrial automation environments.
