ABB AC 800PEC High-Performance Controller

Next-Generation Control Platform

The AC 800PEC is ABB's flagship programmable controller for applications requiring extreme speed, determinism, and reliability. It builds on the success of the AC 800 family while adding specialized processing capabilities for power electronics, such as turbine control, static excitation systems (SES), and high-power drives.

Hardware Architecture

• Multi-Core CPU: 1.2 GHz dual-core processor with floating-point unit, handling complex algorithms and logic simultaneously.

• Redundant Configuration: Supports CPU, communication, and power redundancy for SIL2/3 safety applications.

• I/O Flexibility: Mix of standard 800xA I/O and high-speed PEC I/O with 1 μs time stamping.

• Integrated HMI: Optional local panel with web-based visualization.

Performance Specifications

Typical Applications

AC 800PEC is the core of ABB's UNITROL excitation systems, Symphony Plus turbine controls, and marine propulsion drives. It handles tasks from simple sequencing to advanced model predictive control.

Software Environment

Engineering is performed using ABB's Control Builder M, which offers a single development environment for configuration, simulation, and diagnostics. Libraries include pre-tested function blocks for power industry standards, reducing project risk.

With its proven track record in thousands of high-value installations, the ABB AC 800PEC sets the benchmark for control performance and lifecycle support.
