ABB AO845 3BSE023676R1 – 8-Channel Single/Redundant HART Analog Output Module for S800 Distributed I/O System Official Function Description This 8-channel analog output module belongs to ABB S800 I/O series, designed for System 800xA DCS process control systems. It converts digital control signals from AC800M controllers into standard 4–20mA analog output signals to drive field actuators (control valves, positioners, variable regulators). Integrated HART bi-directional communication enables parameter configuration, online diagnostics and status reading for HART-compatible smart valve positioners. The module supports both standalone single installation and fully redundant hot-backup rack configuration, with full hot-swap capability for non-stop plant maintenance. It provides channel-level s
