AO845 3BSE045584R1 ABB Analog output module High reliability Compatible with AC 800M control systems
The ABB AO845 (Order Code: 3BSE045584R1) is a high-density, 16-channel analog output module engineered for the ABB AC 800M programmable automation controller (PAC) within the System 800xA distributed control system (DCS). Designed for space-constrained and cost-sensitive applications without compromising performance, the AO845 delivers reliable current output signals (0/4–20 mA) with 16-bit resolution, per-channel diagnostics, and full compatibility with ABB’s unified engineering environment. It is ideal for driving control valves, actuators, VFDs, and other analog field devices in power, water, oil & gas, chemical, and industrial automation systems.
