ABB AO810 / 3BSE008522R1 S800 I/O 8-Channel Analog Output Module

The ABB AO810 (3BSE008522R1) is a legacy 8-channel analog current output module for the S800 I/O system. It provides 0–20 mA and 4–20 mA outputs with 14-bit resolution, fault diagnostics and configurable Output Set as Predetermined handling.

The ABB AO810, article number 3BSE008522R1, is a legacy 8-channel unipolar analog current output module for the ABB S800 I/O platform. It generates 0–20 mA or 4–20 mA control signals for industrial field devices such as valve positioners, I/P converters, actuators and variable-speed drive references.

The module offers 14-bit resolution, a maximum specified error of 0.1% at loads from 0 to 500 Ω, a rise time of approximately 4 ms and an update cycle of no more than 2 ms. Output Load capacity depends on the selected external power-supply connection: up to 500 Ω with supply connected to L1+, or 250–850 Ω with the appropriate L2+ supply arrangement. The eight channels are isolated together as one group from ground rather than individually isolated.

AO810 includes open-circuit and process-power supervision. Its Output Set as Predetermined function can move outputs to configured values following specified communication or module faults. A compatible S800 TU/MTU termination unit and external 24 V process supply are required. Confirm the exact module revision, MTU, load resistance, power wiring and control-system compatibility before ordering.
