Read verified buyer reviews ↓OverviewThe Siemens 6EP1961-2BA31 SITOP PSE200U 3A Selectivity Module is a vital element for improving the dependability and efficiency of 24V DC power distribution in demanding industrial settings. This sophisticated module actively observes and secures essential systems by selectively isolating faulty circuits, preventing widespread interruptions, and ensuring uninterrupted performance of unaffected sections. Featuring four individually adjustable output channels, each offering a current threshold from 0.5A to 3A, the 6EP1961-2BA31 delivers precise protection for a broad array of connected loads. Real-time status indicators for every channel enable swift fault identification, minimizing downtime and streamlining maintenance. Designed to Siemens' high-quality benchmarks, this compact and sturdy selectivity module is engineered for effortless integration into existing control panels, providing improved system resilience and continuous operation.Key Features Intelligent Circuit Isolation: Prevents overall system failures by disconnecting only the affected faulty circuit, maintaining power to critical, unaffected components. Four Flexible Output Channels: Each of the four outputs can be individually configured with a current threshold between 0.5A and 3A, offering accurate and adaptable protection for diverse loads. Instant Status Feedback: Clear LED indicators for each output channel provide immediate visual information on operational status, allowing for quick and efficient troubleshooting. Increased System Availability: By effectively isolating faults, the module considerably reduces downtime, contributing to greater productivity and operational efficiency. Compact and Efficient Design: Engineered with a minimal footprint (72mm W x 80mm H x 72mm D), making it perfect for installation in confined control cabinets and panels. Simple Setup: Front-facing potentiometers facilitate straightforward and intuitive adjustment of current thresholds, simplifying configuration and activation. Durable Industrial Reliability: Constructed to Siemens' rigorous quality and performance requirements, guaranteeing long-lasting dependable performance in harsh industrial conditions.
