The Pilz PNOZ E2.1P 24VDC 2SO is a specialised safety relay engineered to monitor and control two-hand operator devices in compliance with Type III C requirements. As part of Pilz’s reliable PNOZ range, this relay plays a vital role in preventing unintended or unsafe machine activation, making it a cornerstone of operator safety in industries where manual interaction with hazardous machinery is required.

Designed to operate on a 24 V DC supply, the PNOZ E2.1P integrates seamlessly into modern automation and safety architectures. Its design ensures efficient operation with reliable performance in continuous duty applications. For added protection, the relay is safeguarded through device circuit breakers rated at 6 A slow-blow or 10 A quick-acting fuses, ensuring durability against overloads and faults.

The unit is optimised for two-hand control monitoring in accordance with EN 574 Type III C. This means that operators must press both control buttons simultaneously within a defined time window for machine activation. If one button is released or not pressed within the time tolerance, the machine remains disabled or is immediately stopped. This functionality ensures that the operator’s hands remain safely away from hazardous areas during critical machine operations, such as pressing, stamping, or cutting.

Equipped with two semiconductor outputs (SO), the PNOZ E2.1P provides fast, wear-free, and reliable switching. Semiconductor technology eliminates the mechanical wear associated with electromechanical contacts, making the relay suitable for applications requiring high switching frequency or continuous operation. These outputs provide precise and consistent signalling to actuators or higher-level safety controllers, ensuring accurate machine shutdown or enabling.

In compliance with EN 60947-1 utilisation category DC-12, the relay is suitable for switching resistive DC loads, ensuring long-term reliability in industrial environments. This compliance guarantees robust operation and compatibility with a wide range of control devices and circuits.

The rugged construction of the PNOZ E2.1P ensures dependable performance in demanding environments, while its compact design makes installation simple and efficient. Clear terminal assignments and straightforward integration reduce commissioning time and minimise errors during setup.

Applications for the PNOZ E2.1P are most common in industries such as metalworking, automotive, packaging, woodworking, and robotics, where two-hand control systems are critical for protecting operators during potentially dangerous machine movements. By enforcing strict two-hand actuation, it ensures machines cannot be started unintentionally, reducing the risk of accidents and enabling compliance with international safety standards.

In summary, the Pilz PNOZ E2.1P 24VDC 2SO delivers energy-efficient DC operation, high-integrity two-hand monitoring, semiconductor output reliability, and standards-based compliance. It is a trusted safety relay solution that enhances operator safety and ensures reliable protection for both personnel and machinery in high-risk industrial applications.
