PRODUCT INFORMATION
Product Overview
The ABB AO815 3BSE052605R1 is an S800 I/O analog output module designed for process control. It provides eight unipolar 4 to 20 mA analog output channels with 12-bit conversion resolution. The module features groupwise isolation from ground and supports point-to-point HART pass-through communication. The output filter must remain enabled on any channel running HART communication.
The unit provides short-circuit proof outputs with current limiting up to a maximum 750 ohm load. Internal supervisory diagnostics monitor for low output power and open-circuit conditions when current exceeds 1 mA. Front-panel indicators report Fault, Run, Warning, and Output Set as Predetermined operational states. Field connections reach up to 600 meters and interface through modular terminal units including TU810 and TU830.
