ABB HC800 | High-Performance Controller for Symphony Plus DCS
Redundant Design, Multi-Processor Parallel Computing, PN800 Plant Network Integration for Power Generation, Oil & Gas, Petrochemicals
1. Product Overview
The ABB HC800 is a high-performance redundant controller for the ABB Symphony Plus distributed control system (DCS), engineered to deliver reliable, real-time process control and seamless integration with I/O modules, communication processors (e.g., CP800), and operator stations in mission-critical industrial environments. It features a redundant architecture with dual 32-bit ColdFire processors (256 MHz), 64 MB RAM, and 4 MB ROM, enabling parallel processing of control algorithms, data acquisition, and system diagnostics for fast, deterministic control responses. The HC800 integrates the PN800 Plant Network for high-speed inter-controller, controller-to-I/O, and controller-to-server communication, supporting hot-standby operation for uninterrupted control during component failure. With a 24 VDC system bus power supply, operating temperature range of 0°C to +70°C, and compliance with IEC 61010-1 and UL 508 safety standards, it ensures robust performance in power generation, oil & gas, petrochemical, and pulp & paper applications, serving as the core of scalable, fault-tolerant DCS solutions with minimal downtime and maximum operational efficiency.
