Honeywell 51403626-200 Control Module – TDC 3000 Series
Imagine a continuous process plant — a refinery, a chemical reactor, or a power generation unit — suddenly losing its primary control loop coordination. Without a functioning control module at the heart of the Distributed Control System, operators lose real-time process visibility, regulatory control loops go open, and the risk of unplanned shutdown or safety exceedance rises sharply. Every minute of downtime in such environments translates directly into production loss and potential safety incidents. The Honeywell 51403626-200 Control Module is the critical component that prevents this scenario, serving as the processing backbone of the TDC 3000 DCS architecture.
The 51403626-200 occupies a well-established position within Honeywell’s TDC 3000 (Total Distributed Control) platform — one of the most widely deployed DCS families in the global process industries. Introduced and refined over decades of field deployment, this module has earned a reputation for reliability in demanding environments including oil & gas, petrochemical, pulp & paper, and power generation. Its continued availability as a spare part is essential for the thousands of TDC 3000 installations still operating worldwide, making it a high-demand component in the industrial MRO and automation aftermarket.
