ABB AO815 S800 Analog Output Module
The ABB AO815 (3BSE052605R1) is an 8-channel analog output module built for the ABB S800 I/O system within the System 800xA platform. It generates unipolar 4–20 mA current signals to drive process devices such as control valves, actuators, and variable speed drives.
Signal Handling and Diagnostics
All 8 channels share a common ground isolated from system electronics. The AO815 features advanced fault monitoring, including open circuit, short circuit, and output transistor failure detection. Continuous cyclic self-checks and checksum verification help ensure reliable signal integrity and early fault identification.
HART Passthrough and Field Maintenance
The module supports point-to-point HART communication across each 4–20 mA loop when the output filter is enabled. Its modular housing mounts directly onto standard DIN rail baseplates and supports hot-swapping, enabling module replacement while the system remains powered and operational.
