Legacy Honeywell DCS Migration
Replace Your Legacy Honeywell TDC2000 or TDC3000 System by Plugging In a Brand-New, Low-Cost, No-Risk I/A Series System


Your legacy Honeywell TDC2000 or TDC3000 system needs to be replaced, but you cannot afford the high cost, the high risk, and the lengthy process downtime. Only the Invensys OperationsManagement migration solution was designed with these needs in mind. The Foxboro® I/A Series® System is the most intelligent automation solution on the planet. It boasts the industry’s highest uptime availability record. It offers state-of-theart operating systems, workstations, control software, and high-speed communications. Plus its InFusion™ architecture leverages the latest technologies fromInvensys and third-party suppliers, today and tomorrow.


Foxboro manufactures its standard I/A Series I/O modules to be one-for-one, form-fit replacements for your legacy TDC2000 or TDC3000 I/O modules. We install these modules into your existing cabinets and racks without moving a single process wire or increasing your system footprint. They line up exactlywith your I/O points. We add our own network connectors and add new I/A Series controllers and workstations, resulting in a 100% new I/A Series system. Substantial construction costs and lengthy process downtimes caused by rewiring to new cabintets are eliminated, and installation is reduced to a matter of hours. And we warranty the entire system, including leftover legacy components, as a newsystem.
