216VC62A/P1000 HESG324442R112 is an ABB Advant OCS Series Analog Input/Output (AI/AO) Combo Module (also referred to as ABB HESG324442R112 Industrial Process Signal Interface Module, Advant OCS High-Precision I/O Module), a core signal processing component designed for ABB Advant Open Control System (OCS) to enable bidirectional analog signal exchange between the DCS controller and field devices in industrial process control applications.

The 216VC62A/P1000 HESG324442R112 module is a high-performance industrial analog I/O combo module developed by ABB, tailored for the Advant OCS—ABB’s legacy modular process control platform widely deployed in critical process industries. Its primary function is to accurately acquire analog signals from field sensors (e.g., temperature, pressure, flow transducers) via dedicated AI channels and output precise analog control signals to actuators (e.g., control valves, variable frequency drives) via AO channels, serving as a critical link between the Advant OCS controller and field equipment.

Featuring a rugged industrial design optimized for harsh process environments, the module integrates advanced signal conditioning circuits, high-isolation components, and anti-interference technology to ensure stable operation in conditions with temperature fluctuations, vibration, electrical noise, and humidity—common in petrochemical plants, refineries, power stations, and chemical processing facilities. It supports multiple industry-standard analog signal types, enabling compatibility with a wide range of field devices without additional signal converters.

Seamlessly integrating with the Advant OCS system backplane and ABB’s Control Builder software, the module supports flexible configuration, signal scaling, and advanced diagnostic functions. It is widely used in legacy process control systems requiring high-precision analog signal processing, enabling reliable process monitoring and control to optimize production efficiency and ensure process stability.
