Product Introduction
The Emerson KJ2003X1-BA2 is a powerful and highly reliable controller module designed for use in DeltaV™ distributed control systems (DCS). As part of the DeltaV automation architecture, this controller plays a central role in process control, real-time data acquisition, and system-wide coordination. Engineered for critical process environments, it integrates seamlessly with the broader DeltaV system, providing fast, deterministic control performance with built-in redundancy and system diagnostics.
The KJ2003X1-BA2 supports complex control strategies, including regulatory, sequential, and advanced process control (APC), all managed within the DeltaV control strategy framework. With native communication to field devices, peer controllers, and operator stations, this module ensures tight integration and high system availability.
