ABB HART Module

The ABB AO815 (3BSE052605R1) is an 8-channel analog output module from the S800 I/O system, designed for ABB System 800xA DCS and AC 800M controllers. It provides 4...20 mA current signals to control field actuators such as valves, positioners, and variable speed drives, while integrated HART pass-through enables two-way digital communication with smart field instruments.

The ABB AO815-eA (3BSE052605R2) is an 8-channel analog output module from the S800 I/O system, designed for the System 800xA DCS and AC 800M controller platform. Each channel provides 4...20 mA (or configurable 0...20 mA) output with HART pass-through communication, enabling seamless integration with smart field instruments such as positioners, valves, and actuators.
