Honeywell 51403776-100 Controller Card – Process Control Module for TDC 3000 DCS
When a controller card fails in a distributed control system, the consequences extend far beyond a single loop going offline. Entire process units can trip, safety interlocks may activate, and unplanned shutdowns in refining, chemical, or power generation facilities can cost tens of thousands of dollars per hour. The Honeywell 51403776-100 Controller Card is the critical intelligence layer that keeps your TDC 3000 DCS running with precision and reliability — its absence is not an option in any continuous-process environment.
The 51403776-100 occupies a well-established position within Honeywell’s TDC 3000 (Total Distributed Control) platform — one of the most widely deployed DCS architectures in the global process industries. Designed for high-availability control environments, this card delivers deterministic scan-cycle performance and seamless integration within the TDC 3000 Local Control Network (LCN) and Universal Control Network (UCN) architecture. Its installed base spans refineries, petrochemical complexes, pulp and paper mills, and power plants across six continents.
