The Pilz PNOZ E2.2P 24VDC 2SO is a high-performance safety relay designed to monitor two-hand control devices in accordance with Type III A requirements. As part of the trusted PNOZ family, this unit ensures reliable operator protection and machine safety by enforcing the use of both hands during machine actuation, preventing unintended or unsafe operation.

Operating on a 24 V DC supply voltage, the PNOZ E2.2P is tailored for modern control systems that use low-voltage safety components. Its design ensures reliable functionality with low energy consumption, supporting continuous operation while maintaining high levels of safety integrity.

One of the defining features of this device is its suitability for two-hand control applications (Type III A). By requiring operators to press and hold two separate control buttons within a specified time window, the relay ensures that both hands are kept away from hazardous areas during machine activation. This functionality is particularly critical in environments such as metalworking presses, stamping machinery, and other equipment where operator hands must be safeguarded from danger zones.

The relay is equipped with two semiconductor outputs (SO), which provide fast and reliable signal switching without mechanical wear. Compared to traditional relay contacts, semiconductor outputs offer extended service life, high switching frequency, and reduced maintenance needs, making the device especially suitable for applications requiring continuous or rapid cycling.

For electrical safety and durability, the PNOZ E2.2P is rated under the DC-12 utilisation category according to EN 60947-1, ensuring suitability for resistive DC loads. The device is also protected by circuit breaker specifications of 6 A slow-blow or 10 A quick-acting fuses, safeguarding the relay and connected systems against overloads and short circuits.

Built with industrial robustness, the PNOZ E2.2P ensures reliable operation in demanding environments, supporting machine builders and operators in maintaining high system availability. Its compact form factor and clearly labelled terminals simplify wiring and installation, reducing setup time and minimising the risk of errors.

The relay’s ability to enforce safe two-hand operation makes it indispensable in industries such as metal forming, packaging, woodworking, robotics, and general manufacturing, where operator safety during hazardous machine movements is a top priority. By ensuring compliance with international safety regulations, it helps manufacturers meet both operational and legal safety obligations.

In summary, the Pilz PNOZ E2.2P 24VDC 2SO delivers energy-efficient DC operation, dedicated two-hand control monitoring, robust semiconductor outputs, and compliance with safety standards. It is a reliable and durable safety relay solution that enhances operator safety and supports efficient, compliant, and productive machine operation across a broad range of industrial environments.
