Honeywell 51304542-100
Overview:
The Honeywell 51304542-100 is an industrial-grade PCB control board for the TDC 3000 / TPN system. It acts as a key I/O control interface, handling communication between logic control signals and field devices via the LCN (Local Control Network) proprietary bus protocol. Publicly available documentation shows slight variation in categorization—some references classify it as a “KLCN I/O Control Board,” while others describe it as an “LCN A Cable Interface Converter Board.” Both descriptions point to the same core function: LCN-bus-based interface/conversion for TDC 3000.
