ABB CI840A 3BSE041882R1 PROFIBUS DP-V1 Interface Module

Overview
The ABB CI840A (part number 3BSE041882R1) is a high-performance PROFIBUS DP-V1 communication interface that links any ABB S800 I/O station to PROFIBUS DP-V1 masters such as AC 800M controllers, PLCs or SCADA systems. Designed for 24/7 process industries, the module delivers deterministic data exchange, modular scalability and hardware redundancy in a single, hot-swappable unit.

Key Features & Benefits
• Full PROFIBUS DP-V1 compliance – operates as slave or master, supports cyclic & acyclic data, automatic baud-rate detection up to 12 Mbit/s.
• Redundancy-ready – dual CI840A units can be configured for seamless switch-over, eliminating single points of failure.
• Hot-swap capable – insert or remove the module under power without interrupting the process; MTTR < 1 min.
• Industrial durability – -20 °C … +60 °C operating range, 24 VDC ± 20 % supply, <5 W power draw, conformal-coated PCB for harsh environments.
• Compact footprint – 127 × 102 × 178 mm, DIN-rail mount, only 0.5 kg.
