Honeywell 51305896-200 NIM Modem Board – TDC 3000 Network Interface Module
When a Network Interface Module fails in a live TDC 3000 distributed control system, the consequences are immediate and severe: communication between the Universal Control Network (UCN) and field devices collapses, process data stops flowing to operator consoles, and plant engineers face unplanned downtime that can cost thousands of dollars per hour. In high-stakes environments such as oil refineries, chemical plants, and power generation facilities, a missing or faulty NIM is not a minor inconvenience — it is a production-stopping event. The Honeywell 51305896-200 NIM Modem Board is the critical link that keeps your TDC 3000 system talking.
The 51305896-200 is a modem board sub-assembly designed specifically for the NIM (Network Interface Module) within Honeywell’s TDC 3000 DCS platform — one of the most widely deployed distributed control architectures in the global process industry. As a core communication component, this board handles the physical-layer modem functions that enable reliable data exchange across the Local Control Network (LCN) and UCN backplane. Its continued availability is essential for the tens of thousands of TDC 3000 systems still operating worldwide, making it one of the most sought-after legacy DCS spare parts in the industrial automation market.
