System Architecture & Signal Flow
The 51401594-200 PCB board interfaces directly with the TDC 3000 backplane via the standard card-edge connector. It participates in the Local Control Network (LCN) or Basic Controller (BC) subsystem depending on system configuration. Signal conditioning, A/D conversion, and control output logic are executed on-board, reducing latency and improving loop stability. The module communicates with the Honeywell Universal Control Network (UCN) through the system’s standard data highway architecture.
