HC800A ABB Symphony Plus HPC800 Control Processor Module

Product Description
HC800A is the main control processor module for ABB Symphony Plus HPC800 DCS controller, with conformal coating. It executes process control logic, handles real-time data exchange with I/O modules and operator stations, and supports up to 30,000 function blocks. This CPU adopts redundant design capability and HN800 fiber communication bus for connection to Symphony Plus S+ series I/O modules. It is widely used in power plant boiler, turbine and industrial large-scale process control systems, serving as core spare part for Symphony Plus platform maintenance.

• Oil & gas process plant, district heating central control room
• Symphony Plus system upgrade, redundant CPU spare replacement and retrofit projects

FAQ

Q: What is the difference between HC800 and HC800A?
A: HC800A has conformal coating, suitable for harsh environment; standard HC800 without coating, for clean control room.

Q: What base does HC800A use?
A: MB810A mounting base for rack installation.

Q: Does HC800A support redundant configuration?
A: Yes, dual HC800A can be configured as redundant controller pair for no-break process control.
