ABB 3BHE006805R0001 DDC779BE01 Process Control Module for AC800PEC & ACS6000

Product Overview

The ABB 3BHE006805R0001​ is the order-code designated DDC779BE01 process control module—a controller-class board that functions as a real-time control and signal-coordination node within ABB’s industrial automation and drive architectures. Depending on the platform configuration in which it is deployed, the ABB 3BHE006805R0001​ appears either as a distributed controller module in ABB DCS environments (AC800PEC, Advant OCS, and related process control families) or as a control board inside ABB medium-voltage drive systems such as the ACS6000, where it executes control algorithms and coordinates signals between the controller and the power section.

The basic definition of the ABB 3BHE006805R0001​ is that of a deterministic, industrial-grade processing module: it acquires process signals from the field, executes control logic—PID loops, sequence control, and interlocking—and issues commands to actuators, drives, and downstream controllers. Its role is to sit between the higher-level system bus and the I/O or power-stage layer, performing the millisecond- and microsecond-scale decisions that the supervisory layer is too slow to handle. In a DCS deployment this means closed-loop regulation of process variables; in a drive deployment it means the control algorithms that govern energy conversion and motor behavior.

The value of the ABB 3BHE006805R0001​ lies in its combination of processing capability, redundant operation, and industrial ruggedness. It supports primary/backup redundant configurations, where a standby module runs in lockstep with the active unit and can take over in approximately 100 milliseconds—fast enough that operators and field devices notice no interruption. Hot-swappable installation means a failed board can be replaced without powering down the entire rack. With a 32-bit RISC processor, 4 MB of application and data memory, multi-channel analog and digital I/O handling, and support for Profibus-DP, Modbus RTU, and other industrial protocols, the ABB 3BHE006805R0001​ is built for continuous-duty process environments where downtime is measured in lost production rather than repair time.
