A Distributed Control System (DCS) is a control system for processes within a large-scale, automated application. A hierarchy of controllers is connected to a communications network which allows for command and monitoring. Simply put, the DCS runs the show. Some common areas you’d find a DCS include petrochemical companies, water management, nuclear power plants and other large-scale technical operations.

Because the DCS is so powerful, it’s also large, complicated and expensive. For that reason, when there’s a problem with any component of a DCS, replacement is rarely the first option. Instead, DCS problems require repairs.

At Haygor, we provide DCS repair solutions. No matter how complicated the issue, we’ll have you up and running soon. We repair to component level:

  • Field Termination Assembly (FTA) modules
  • Input/Output Processor modules (used in Honeywell’s TDC3000 Process Manager and Advanced Process Manager Systems)
  • Any other aspect of the DCS System

The most common manufacturer of DCS systems is Honeywell. While we’re experts in the service and repair of Honeywell DCS, we can also repair most other major brands as well. Our technicians have over 50 years of combined experience with industrial repair in the petrochemical industry.
