The AC 800PEC system incorporates equipment that meets the most challenging – and also contradictory – requirements in process control. It includes a wide range of I/O modules to cover all power electronics control requirements.
The different I/O modules can be connected to the AC 800PEC controller to cover most automation requirements in:
• Process industry • Power generation and distribution • Transportation and traction
The modular, energy-efficient design of the AC 800PEC allows operation without forced cooling. The modules are mounted on standard DIN rails and can easily be installed in distributed processes . The number of directly connectable I/O systems is limited only by the maximum available fiber-optic links to the processor (36 bidirectional links ). Depending on the required performance, single, multiple, or redundant bidirectional links are used between modules. Each module comprises a mechanical carrier, a base module, and a configurable set of submodules that provide the required I/O terminals or communication interfaces.
AC 800PEC Controller PP D113:
The controller comprises a low-power circuit with high reliability. The hardware can be configured freely, depending on the process requirements and the selected communication with the upper control. The AC 800PEC controller module contains the processor, the optical interfaces to the peripheral I/O, the fieldbus, and interfaces to the upper control.
AC 800PEC Combi IO UA D149:
The Combi IO UA D149 is a universal, remote I/O device for high-speed applications and is part of the AC 800PEC control system. It is mainly used for sensing actual values in fast closed-loop control and protection circuits.
The Combi IO comprises the basic module UA D141, which can be equipped with stackable I/O boards such as:
• Up to 2 Mixed IO boards UA D142, each providing
– 16 fast digital inputs / 8 fast digital outputs
– 6 fast analog inputs
– 2 fast analog outputs.
• Alternatively: 1 Traction Module DA D143, providing
– 13 analog inputs with various predetermined characteristics
– 18 digital inputs allocated to specific monitoring tasks.
In order to adapt to various voltage and current levels, the Combi IO can be combined with low-voltage divider boards (up to 1000 Vrms) and CT/VT sub-boards.

AC 800PEC Measuring Interface PECMI UA D140:
The Measuring Interface PECMI provides a high-speed current- and voltage-measurement device which supplements the Combi IO module.
• Active scalable inputs for up to 4 current sensors (e.g., LEM) are provided
• Inputs for voltage divider boards and CT/VT sub-boards are available.
To adapt to various voltage and current levels, the PECMI can be combined with voltage divider boards:
– Voltages up to 1000 Vrms require a Low Voltage Divider (LVD)
– Higher voltages up to 6000 Vrms require the High Voltage Divider (HVD).
Standard ABB S800 I/O System:
For slow process signals, the standard ABB S800 I/Os provides a large and flexible interface with a virtually unlimited number of analog and digital I/Os.

AC 800PEC INT Interface System PV D164:
The PEC INT board comprises up to six optical modules with 6 transmitter/receiver channels to interface with the AC 800PEC control system and various converter types, e.g., for direct-firing pulse transmission to IGCT converters. The complete pulse logic is implemented in a programmable logic (FPGA) on the PEC INT board.

AC 800PEC PEBB Interface Boards GD D160 and GD D165:
The PEBB Interface Board is a universal remote I/O device for the direct drive of two IGBT converters with up to 2 x 6 pulses within ABB's "Power Electronic Building Block (PEBB)".
It also measures and monitors all analog and digital signals from the two IGBT converters. Six additional parallel IGBT converters can be driven via extension interfaces.
A measuring interface, PE C, MI can be connected for current and voltage sensing devices.
The PEBB Interface Quad GD D165 can be used as an alternative universal remote I/O device to drive up to four IGBT bridges with up to 4 x 6 pulses within a "Power Electronic Building Block (PEBB)".
