Large-scale power converters and drives
must be reliable, fast and precise. That
calls for a control system with outstanding
performance, such as the AC 800PEC.
But why should the same controller not
cope with slow processes, too, such as
cooling circuits, monitoring and balance
of plant?
The AC 800PEC does it all: when it comes
to high-speed processes in an industrial
environment with all related ancillary
tasks, it is the ideal controller.

The AC 800PEC is ABBs high-end process
control system, and belongs to the Control IT
product line.
The AC 800PEC is the optimum solution
for combining
•the high-speed control requirements
of power electronics applications
•low-speed process control tasks
usually carried out by separate
PLC units.
The AC 800PEC controller is configured and
programmed using Control Builder M, ABB’s
well-established programming tool, and
MATLAB®/ Simulink® with Real-Time
Workshop®.

Key benefits
The AC 800PEC is a modular high-speed
control system. The modules are
arranged according
to the required I/O
configuration
and the process.
The AC 800PEC I/O
modules are
connected
via optional
high-speed
point-to-point
connections.
The AC 800PEC supports up to
36 bi-directional fiber-optic
PowerLinks.

Performance
The AC 800PEC excels with a very high
processing speed. It provides
•Very fast analog and digital process I/Os with
a typical cycle time of 25 µs
•Fast closed-loop control and regular process
logic implemented in one controller
•Low-speed I/Os with a typical cycle time of
10 ms
•Very fast analog/digital conversion and
nominal/actual value comparison, directly on
the peripheral I/O module.
