The Pilz PNOZ E2.1P C 24VDC 2SO, part number 784136, is a specialist safety relay from the Pilz PNOZ range, designed to ensure maximum operator protection through reliable monitoring of two-hand control devices (Type III C). This safety relay plays a vital role in machinery where operators must use both hands to initiate or maintain a function, thereby preventing accidental or hazardous single-hand activation.

Operating on a 24 V DC supply, the PNOZ E2.1P C is fully optimised for integration into modern industrial control panels and automation systems. It is built to function reliably with low power requirements, making it both efficient and practical in safety-critical installations.

At its core, the device is engineered to meet the strict requirements of Type III C two-hand controls, ensuring that both hand-operated actuators must be pressed within a defined time frame to allow machine operation. If only one actuator is pressed, or if there is a delay between the two, the relay prevents activation, effectively eliminating the risk of bypassing or accidental start-up. This functionality is particularly important in applications such as presses, cutters, stamping machines, and other equipment where operator presence must be carefully controlled.

The relay provides two signalling outputs (SO), designed to deliver reliable status feedback to higher-level controllers or monitoring systems. These outputs improve diagnostic capability and allow maintenance teams to quickly assess operational conditions, thereby reducing downtime and ensuring system transparency.

The safety performance of the PNOZ E2.1P C is reinforced by compliance with EN 60947-1 (utilisation category DC-12). This ensures the device is suitable for controlling resistive loads in DC circuits, while maintaining safe and consistent switching performance. Furthermore, the relay is compatible with protective devices rated at 6 A (slow-blow) or 10 A (quick-acting), providing flexibility in circuit design and ensuring safe coordination with other protective components.

Built with high-quality electromechanical components, the relay offers long service life and robust operation, even under the rigours of continuous use in demanding industrial environments. Its compact and practical design allows for straightforward installation and integration into safety architectures, reducing wiring effort and supporting cost-effective implementation.

Applications for the PNOZ E2.1P C are found across industries where machine operators interact directly with hazardous equipment. Common uses include mechanical presses, automated cutting systems, stamping machines, and assembly equipment, where enforced two-hand control is critical to operator safety.

In summary, the Pilz PNOZ E2.1P C 24VDC 2SO (784136) is a reliable, standards-compliant safety relay engineered specifically for monitoring two-hand control devices. With its optimised 24 V DC operation, robust output configuration, compatibility with protective circuits, and adherence to strict safety standards, it provides a trusted solution for safeguarding operators and machinery in high-risk industrial applications.
