WESTINGHOUSE 2840A21G01 Output Analog Board – Ovation Distributed Control System
When an analog output board fails in a power plant or industrial process facility, the consequences are immediate and severe: control loops lose their command signals, actuators freeze in last position, and operators are forced into manual override — risking process instability, unplanned shutdowns, and costly production losses. In critical DCS environments, every minute of downtime translates directly into revenue loss and safety risk. The WESTINGHOUSE 2840A21G01 Output Analog Board is the precision-engineered solution that keeps your control loops alive and your plant running.
The 2840A21G01 is a dedicated analog output board designed for the Westinghouse Ovation Distributed Control System (DCS) — one of the most widely deployed process control platforms in global power generation, including fossil fuel, nuclear, and combined-cycle plants. Within the Ovation architecture, this board occupies a critical role in the I/O subsystem, converting digital control commands from the controller into precise analog signals (typically 4–20 mA or 0–10 V) that drive field devices such as control valves, variable speed drives, and positioners. Its proven reliability and compatibility with the Ovation ecosystem make it a trusted component in plants across North America, Europe, and Asia.
