The Pilz PNOZ E3VP C 300/24VDC 1SO 1SO T (784138) is a reliable and compact safety relay designed to provide dependable monitoring of safety functions in industrial environments. Belonging to the highly regarded Pilz PNOZ product family, it integrates seamlessly into machine safety systems, ensuring the protection of personnel and equipment while supporting compliance with international safety standards.
The relay operates on a 24 V DC supply voltage, making it an ideal choice for integration into modern control architectures. This standardised power input ensures compatibility across a wide range of industrial automation applications, simplifying implementation and reducing wiring complexity.
A key strength of the PNOZ E3VP C lies in its dual semiconductor outputs (SO). Unlike mechanical contacts, semiconductor outputs provide wear-free switching, making the relay particularly suitable for applications requiring frequent switching cycles. This not only improves long-term reliability but also reduces maintenance costs and downtime, enhancing overall equipment effectiveness.
The relay is designed for robust protection, with compatibility for device circuit breakers rated at 6 A (slow-blow) or 10 A (quick-acting). This ensures that the relay and its connected circuits remain safeguarded against overloads and short circuits, preserving both operational integrity and safety.
Compliance with the utilisation category DC-12 (EN 60947-1) further highlights the unit’s suitability for switching resistive DC loads. This makes it particularly valuable in applications where precision and consistency are required for safe machine shutdowns and controlled responses to hazardous events.
In addition, the relay is tested to EN 60068-2-78 for climatic suitability, ensuring reliable operation in humid environments. This resilience makes it a dependable choice in industries such as food and beverage processing, packaging, chemical production, and logistics, where atmospheric moisture can challenge electronic components.
Applications for the PNOZ E3VP C 300/24VDC include the monitoring of emergency stop circuits, safety gates, pressure-sensitive devices, and light curtains. By ensuring that hazardous machine functions are shut down immediately when a fault or emergency is detected, the relay provides a crucial safeguard for workers while maintaining operational efficiency.
In summary, the Pilz PNOZ E3VP C 300/24VDC 1SO 1SO T (784138) is a durable and versatile safety relay that combines 24 V DC compatibility, dual semiconductor outputs, robust breaker protection, and climatic suitability. As part of Pilz’s trusted safety portfolio, it delivers reliable performance and ensures compliance with safety standards across a wide range of industrial applications.
