The Pilz PNOZ S30 24–240VACDC 2N/O 2N/C (750330) is an advanced safety relay from the PNOZsigma range, designed to provide comprehensive motor monitoring and reliable machine safety. With its wide voltage compatibility, versatile outputs, and efficient design, the PNOZ S30 is a trusted choice for safeguarding operators and equipment across a broad spectrum of industrial applications.

One of its most important strengths is its wide supply voltage range. The relay can be powered by both 24–240 V AC/DC, making it adaptable to different system environments without the need for additional conversion components. This capability simplifies global standardisation for machine builders, reducing inventory and increasing flexibility in application design.

The PNOZ S30 is specifically designed for safe standstill and speed monitoring of drives. By ensuring that machines are at a complete stop—or operating below a defined safe speed—before access is allowed, the relay protects operators during maintenance, setup, or intervention tasks. This function is particularly valuable in applications involving high-inertia machinery, conveyor systems, or rotating equipment where unexpected movement could pose serious risks.

The relay provides a flexible contact configuration with two normally open (N/O) safety contacts and two normally closed (N/C) contacts. The N/O contacts can be used to directly switch off hazardous machine functions, while the N/C contacts allow for signalling and feedback into higher-level control systems. This combination ensures both safety integrity and enhanced diagnostic capability, reducing downtime by providing clear system status.

Despite its powerful functionality, the PNOZ S30 maintains energy-efficient performance, consuming only 9 VA (AC) or 5.5 W (DC). Its efficient design is especially advantageous in large-scale installations where multiple relays are deployed, contributing to overall cost savings without compromising safety.

As part of the PNOZsigma family, the relay is built with a slimline 22.5 mm housing that saves valuable space in control cabinets. DIN-rail mounting and clearly marked terminals simplify installation and wiring, ensuring that commissioning is fast and reliable. Once in operation, the PNOZ S30 requires minimal maintenance and delivers dependable performance over a long service life.

The unit’s robust design and compliance with international safety standards make it suitable for use in industries such as packaging, automotive, logistics, and process automation. Wherever drives or motors need to be safely monitored, the PNOZ S30 provides the assurance of dependable safety functionality.

In summary, the Pilz PNOZ S30 24–240VACDC 2N/O 2N/C (750330) is a flexible, efficient, and robust safety relay designed for motor monitoring and machine safeguarding. With its wide voltage compatibility, versatile contact outputs, and reliable speed/standstill detection, it ensures maximum protection for both operators and equipment in modern automated environments.
