TheABB DI840 (3BSE020836R1)is a premium 16-channel digital input module engineered for the S800 I/O system, specifically targeting mission-critical applications. Unlike standard input cards, the DI840 is designed forhigh availability, supporting both single and redundant configurations. With its advanced on-board diagnostics and voltage supervision, it ensures that your AC 800M controller has a reliable, fault-tolerant window into your field operations.
Core Performance Features
Redundancy Ready:Can be deployed in redundant pairs to eliminate single points of failure, ensuring continuous signal monitoring even if one module requires maintenance.
Advanced Self-Diagnostics:Features sophisticated on-board monitoring that detects internal hardware faults and supervises field input voltages, reporting status directly to the 800xA system.
Flexible Termination Options:Highly versatile mounting—compatible with a wide array of Module Termination Units (MTUs) including the TU810, TU842, and TU852.
Compact Reliability:Packs 16 high-integrity channels into a slim 45mm housing, balancing high-density I/O requirements with rigorous industrial safety standards.
