Foxboro AD916CC analog input module

The Field Control Processor 280 (FCP280) is a

distributed, field-mounted controller module that

supports up to 128 DCS FBMs - 32 per HDLC

fieldbus. The FCP280 connects to the control

network via optionally redundant 100 Mbps Ethernet

fiber optic cables and Ethernet fiber switches. The

FCP280 is an optionally fault-tolerant controller that

communicates with connected DCS FBMs to

perform data acquisition and control using Foxboro

Evo control algorithms.

The FCP280 mounts in a 2-position baseplate that

supports a single module or a fault-tolerant module

pair. The baseplate accepts only FCP280 modules.

The FCP280 connects to an optionally redundant

2 Mbps HDLC I/O Fieldbus for communications to

the DCS FBMs and provides galvanic isolation

between the 100 Mbps Ethernet Fieldbus and the

2 Mbps local Fieldbus.

FCP280 modules connect to a pair of copper or fiber

optic network adapters that connect to Ethernet

switches in a redundant control network. The

network adapter pair mounts to the FCP280

baseplate.

To support redundancy, a pair of FCP280s must be

used for each DCS FBM grouping. In non-redundant

configurations, only a single FCP280 is required for

each grouping.

The maximum total cable length for the 2 Mbps

Fieldbus is 60 m (198 ft) within a grouping.

I/O Modules

The DCS FBMs provide advanced 200 Series FBM

technology on an APACS+ module form factor. Each

DCS FBM plugs into the slot used by the replaced

APACS+ module and provides two rear connectors,

one of which mates to a connector on a local field

termination strip on the backplane of the MODULRAC.

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.
