Foxboro FBM203 Input Interface Module

Foxboro Evo™ distributed control system (DCS) Fieldbus

Modules allow migration from Bailey® Network 90 and

INFI 90® process input and output (I/O) components

to a Foxboro Evo process control system.

OVERVIEW

The Foxboro Evo system DCS FBM family provides a

migration path from the Bailey systems process input

and output components to Foxboro Evo display and

supervisory functions. This can save significant cost

over total system replacement by preserving existing

process interface and wiring, and by minimizing

process downtime.

No additional communication devices are required.

No multi-vendor communication software licensing is

required. The DCS FBM family replaces the Bailey

controller and/or slave module devices. Once

integrated, the process is controlled

entirely by the advanced Foxboro Evo algorithm set.

Bailey DCS control devices are disconnected upon

migration, so there is no undesirable interaction

caused by the decommissioned system.

The Foxboro Evo DCS FBM product includes

appropriate connectors to enable integration of

original process signals to Foxboro Evo system while

keeping the field interface and wiring. It provides

access to all process signals connected to the Bailey

system by providing the connection between the

Field Termination Units (FTU) and the Foxboro Evo

system. All process signals become fully integrated

into the Foxboro Evo system. Process data is used

for operator display, history, alarming and control.

Operator functions and engineering configuration are

accomplished by the Foxboro Evo system. Because

all process values become part of the Foxboro Evo

system, all configuration data is maintained by the

system as native Foxboro Evo configurations.

This migration path provides plant operations with

the power and flexibility of the Foxboro Evo system.

All process values can be used plant wide for control,

display, history, alarming, and information

management from a single vendor source.

Control system

Reliable and intelligent, the user-friendly Alfa Laval Touch

Control system provides fully automatic operation of

the boiler plant and the pressure-atomizing burner.

The system includes controls for the burner load and

sequence, burner motor, water level and safety device,

as well as starters for the fuel heater and fuel oil pumps.

The Aalborg i-OC is a vertical and cylindrical boiler

that employs natural circulation of water and steam. Its

pressure sections are manufactured from mild steel that

is able to withstand high temperatures.
