Product Description
The ABB AO815 (3BSE052605R1) is an 8-channel analog output module designed for the ABB S800 I/O system, part of the System 800xA automation platform. It delivers precise 4–20 mA unipolar outputs, ideal for controlling actuators, valves, and process devices in industrial automation systems.
Each channel in the AO815 is electrically isolated from ground, ensuring robust performance and minimizing signal interference. The module supports HART communication in point-to-point mode, allowing real-time field device configuration and monitoring through the same communication line.
Engineered for reliability, the AO815 features advanced diagnostic functions such as open circuit, short circuit, and output transistor fault detection. It also performs cyclic self-checks to maintain stable operation even under harsh industrial conditions. With its DIN-rail mounting and modular hot-swappable design, this module provides flexible installation and minimal maintenance downtime.
