Overview
The ABB DO815 is a digital output module within the S800 I/O family, designed for high-performance distributed control systems. It provides eight current-sourcing digital outputs, grouped into two isolated blocks of four channels each, with built-in protection and diagnostics to ensure safe and reliable operation in harsh industrial environments.
Moreover, the DO815 supports open-load detection, short-circuit protection, and overload monitoring, enhancing system reliability and minimizing maintenance time. In addition, it includes status LEDs and channel-wise error flags for rapid troubleshooting. Therefore, it is widely used in industrial automation, process control, power generation, and infrastructure applications where robust digital output control is required.
