Description
Product Overview
The ABB MB810 is a high-availability, high-performance communication interface module for the ABB AC 800M High Integrity and AC 800M Safety controllers. Specifically designed as a MasterBus 300 Gateway, this module forms the critical communication bridge between the controller’s CPU and the proprietary, deterministic MasterBus 300 field network. The MB810 enables the AC 800M controller to act as the master for extensive networks of ABB’s S800 I/O modules and other compatible devices. Engineered for mission-critical process automation, it prioritizes reliability, fast deterministic data exchange, and seamless redundancy. A defining feature of the ABB MB810 is its capability for full hot-swappable, redundant configuration, ensuring continuous communication and maximum system uptime even during a single module failure. This makes it an essential component for building robust and scalable DCS architectures in industries where process availability is paramount.

Application Scenarios
- High-Availability Process Control: Deploying in redundant configurations in critical DCS applications in oil & gas platforms, power generation, and chemical plants where uninterrupted control is mandatory.
- Distributed I/O Architectures: Serving as the central communication hub for large, geographically dispersed S800 I/O racks in plant-wide control systems.
- System Expansion & Modernization: Adding new I/O clusters to an existing AC 800M-based system via the reliable and proven MasterBus 300 network.
- Safety Instrumented Systems (SIS): Used within AC 800M Safety controller setups to ensure deterministic and reliable communication with safety-rated I/O modules for critical safety loops.
