Product Overview
The ABB AMAR7300 is a highly specialized redundant processor module, meticulously engineered to serve as the core of a fault-tolerant distributed control system (DCS). As a key component of the ABB Advant Master series, this module is designed for applications where system uptime and reliability are absolutely critical. The AMAR7300 operates in a redundant pair, with a primary and a hot-standby unit, ensuring that if the active processor fails, control is seamlessly and automatically transferred to the standby unit without any interruption to the process. This architecture provides an exceptional level of availability, which is paramount in continuous process industries. The ABB AMAR7300 is responsible for executing all control logic, handling complex process management, and managing communication with field devices and other system components. Its robust design and advanced synchronization technology make it a cornerstone for building a highly resilient control infrastructure. The value of the ABB AMAR7300 lies in its ability to protect critical processes from unexpected failures, thereby safeguarding personnel, equipment, and production.
Technical Specifications
Main Features and Advantages
The ABB AMAR7300 module is defined by its core functionality of fault-tolerant redundancy, which provides significant advantages in critical industrial environments. The active/standby architecture ensures that a secondary AMAR7300 module is always ready to take over in the event of a failure in the primary unit. The switchover is performed automatically and in a bumpless manner, meaning there is no interruption to the control signals or the process itself. This capability is a cornerstone for maximizing uptime and minimizing the risk of costly shutdowns. The module’s robust design and advanced internal diagnostics constantly monitor its own health and the status of its redundant partner. This allows for proactive maintenance and helps in quickly identifying and resolving potential issues.
Hot-Swappable Design: The AMAR7300 is designed for hot-swapping, which allows a failed module to be replaced while the system is still running. This simplifies maintenance and eliminates the need for a system shutdown, further contributing to overall availability. The module’s communication capabilities, primarily through the Advant Fieldbus 100, ensure high-speed and reliable data exchange with field devices, I/O modules, and other controllers. This integrated communication platform is optimized for the deterministic control required in process applications. The ABB AMAR7300 is a proven solution for protecting critical operations and ensuring a continuous and stable control environment.
Application Field
The ABB AMAR7300 module is a cornerstone of control systems in high-stakes industries where process continuity and safety are non-negotiable. Its primary application fields are in continuous process industries such as petrochemicals, oil and gas, power generation, and refining. In these environments, the AMAR7300 serves as the central brain of the control system, managing critical processes like distillation columns, reactors, and turbines. It is also used in the water and wastewater treatment sector for managing large-scale purification and distribution systems where uninterrupted operation is vital for public health. The module’s high reliability and redundancy are essential for protecting against failures that could lead to costly production losses, environmental incidents, or safety hazards. The ABB AMAR7300 is also well-suited for older systems that require modern upgrades to a reliable, redundant architecture. Its long-standing presence in the market and proven track record make it a trusted choice for brownfield projects aiming to enhance system resilience.

Installation and Maintenance
Pre-installation preparation: Before installing a redundant pair of ABB AMAR7300 modules, ensure that the control cabinet is completely de-energized. Confirm that the Advant controller rack is correctly installed and that the power supply is functional. The AMAR7300 modules are installed in a designated primary and secondary slot within the rack. It is crucial to have the correct firmware and engineering software, such as ABB’s Freelance or Control IT, to properly configure the modules and the redundancy link. Ensure all bus cables are securely connected and that the system is properly grounded.
Maintenance recommendations: Routine maintenance for the AMAR7300 modules is minimal due to their self-monitoring capabilities. The module’s internal diagnostics will signal a fault, which is crucial for proactive maintenance. If a module fails, it can be hot-swapped while the system is online, with the remaining module taking over control. It is recommended to perform periodic backups of the controller configuration to a secure location. Regularly check the control cabinet’s cooling system to ensure the ambient temperature remains within the specified operating range, which is vital for the longevity of the electronics.
