Description
Product Description
The ABB UDD406A is an 8-channel digital input module for ABB industrial control systems, engineered to capture and transmit digital signals reliably in harsh industrial environments. The ABB UDD406A features 8 isolated 24 V DC inputs, each with 1 ms response time and 5 kV surge protection, ensuring precision in sequence-of-events (SOE) recording and transient immunity. It operates from -25°C to +60°C, with IP20 protection and DIN rail mounting for control cabinet integration, while supporting PROFIBUS DP and Ethernet/IP for seamless communication with ABB AC 800M PLCs and DCS. The ABB UDD406A integrates with ABB Control Builder software, enabling drag-and-drop configuration and real-time diagnostics, with LED indicators for channel status and power to simplify troubleshooting. It uses industrial-grade components for 5g shock and 1g vibration resistance, minimizing downtime in manufacturing, energy, and process automation. The ABB UDD406A also offers 24 V DC (±10%) power input and compliance with EN 61010-1, EN 55022, and IEC 61800-3, ensuring global industrial safety and electromagnetic compatibility. It supports hot-swapping and backward compatibility with legacy ABB systems, making it ideal for upgrading or expanding existing installations with minimal rework.
