Product Details
The DSPC174 3BSE005461R1 is a high‑performance Central‑Computing Processor Board for ABB Advant Master DCS platform, it serves as core Advant Master Main Processing Unit of the control rack and undertakes heavy‑duty process logic computation for industrial automation system.
This processor module supports multiple memory sub‑card assemblies, users can expand RAM and flash storage capacity according to project requirements. It connects with SC‑series sub‑module carrier boards via built‑in MB300 sub‑bus, realizing high‑speed data scheduling and resource management for all kinds of signal acquisition and communication sub‑modules. The external D‑Sub debugging interface supports program download, parameter configuration and on‑line diagnosis for engineering commissioning.
Multi‑LED indicators on front panel reflect processor running status, memory bank state and bus fault information. Complete hardware self‑diagnosis mechanism monitors internal hardware, memory and bus communication anomalies in real‑time. Fault alarms will be uploaded to DCS host through rack backplane, helping maintenance personnel capture hidden risks in advance during site inspection.
Adopting standard rack‑mount mechanical structure, it can cooperate with CI547 communication board to optimize MB300 bus load. Widely deployed in thermal power, pulp‑paper and petrochemical legacy Advant Master DCS projects. It is essential main control hardware for system logic capacity expansion, memory performance upgrading and defective main‑processor replacement for old‑generation Advant automation systems.
