ABB AC 800M Controller

The ABB AC 800M is a modular, high-performance Programmable Automation Controller (PAC) designed for complex control applications in the process industry. It is part of ABB’s Compact Product Suite, offering flexibility, scalability, and robust performance for distributed control systems (DCS), programmable logic controllers (PLC), and safety-critical environments.

Key Features

• Modular architecture with rail-mounted CPUs, communication modules, power supplies, and accessories.
• Seven CPU options ranging from cost-effective models to high-performance units with full redundancy support.
• Advanced control capabilities including rich function block libraries, auto-tuning, and support for ABB drives and motors.
• Integrated Ethernet communication with onboard RNRP redundancy and broad protocol support for third-party device connectivity.
• Superior redundancy concept with fast switchover and topologically separated CPU modules.
• Flash memory card support for remote application loading without engineering tools—ideal for OEM and remote deployments.

Engineering & Programming

• Uses Compact Control Builder software, supporting IEC 61131-3 programming languages.
• Enables centralized management of logic, sequential, and analog control across all controllers in one database.
• Supports priority-controlled, time-based tasks for high stability in demanding control environments.

Benefits

• High availability and fault tolerance for mission-critical operations.
• Flexible I/O integration across a wide range of industrial applications.
• Efficient configuration with reusable libraries and scalable hardware.
• Reduced lifecycle costs through modular design and open architecture.

Applications

• Process automation in chemical, oil & gas, power generation, and manufacturing.
• Safety systems with certified high-integrity modules.
• OEM solutions and remote installations requiring compact, reliable control.

The AC 800M is an extremely powerful controller which is an integral part of the ABB 800xA platform and can also be used in conjunction with ABB Compact HMI and other third-party HMIs.
