Core Features & Customer ValueThe controller’s high-performance processor provides substantial computational power for complex control strategies including multi-variable predictive control, custom algorithms, and sophisticated sequencing logic. For process engineers, this enables implementation of advanced control schemes that improve process stability, product quality, and energy utilization. The deterministic execution ensures consistent control loop performance, which is critical for maintaining process variables within tight tolerances in continuous process industries.Integrated support for multiple fieldbus protocols allows the controller to communicate with a wide range of field devices and remote I/O stations. This flexibility enables integration of diverse equipment into a unified control strategy, reducing system complexity and lifecycle costs. The controller’s high availability features, including 1:1 redundancy support, ensure continuous operation even during maintenance activities or component failures.Typical ApplicationsIn chemical processing plants, the 3BDH000320R0101 executes batch recipes for reactor control, managing precise temperature and pressure profiles while coordinating material addition and product transfer sequences. The batch management capabilities ensure recipe consistency and regulatory compliance.In power generation facilities, the controller manages turbine control, boiler management, and balance-of-plant systems. The wide operating temperature range makes it suitable for installation in both control rooms and field enclosures where environmental conditions may vary.
