Overview

The EcoStruxure™ Foxboro™ DCS Field Mounted Intelligent Enclosure provides an

integrated solution designed to be mounted close to instruments in the field to reduce

cables. The Field Mounted Enclosure includes Universal Input/Output (UIO) modules,

power supplies, and Termination Assemblies (TAs) that are pre-installed and tested,

and can be connected to a wide range of field devices. The enclosure supports

Schneider Electric’s Flexible Lean Execution strategy, which shortens project

schedules and reduces the risk of startup delays.

The Field Mounted Intelligent Enclosure is designed to be mounted in the field, and

connects through redundant single mode fiber to the Field Control Processors located

in the Equipment Room Intelligent Enclosure. For more information, refer to

Equipment Room Intelligent Enclosure (PSS 41H-2I30).

The enclosure supports up to 64 standard Universal I/O channels in simplex,

redundant, or simplex and redundant combinations, and optionally accommodates

integration of third party PLCs using simplex or redundant Field Device System

Integration modules supporting Modbus TCP.

A second enclosure can be cascaded from the first enclosure using single mode fiber

or copper cable, saving on communication home run cable to the equipment room.

Field cables, communication cables, and power cables enter the enclosure through

cable glands or a multi-cable transit (optional) located at the bottom of the enclosure.

The channel-to-channel isolated Universal I/O Module supports DI, DO, AI, AO,

HART, NAMUR, Pulse, and 1 ms SOE signal types.

Field cables terminate directly on Termination Assemblies (TAs) with signal

conditioners for optional field signal processing. Refer to Termination Assemblies and

Signal Conditioners, page 8.

Terminals are provided to terminate spare field cable cores and screens. This rugged,

unpainted SS316L stainless steel enclosure can be mounted in harsh environmental

and hazardous areas.

Features

• Protection against harsh environments and hazardous locations:

◦ NEMA® 4X/IP66 rated

◦ Class G3 (harsh) environment

◦ ATEX

• Universal I/O and TAs support any one of these options:

◦ 64 Simplex I/O

◦ 64 Redundant I/O

◦ 48 Simplex and 16 Redundant I/O

• Up to 16 Universal Standard I/O modules (8 x FBM247, 16 x FBM248, or

4 x FBM248 and 6 x FBM247) that support 64 simplex, redundant, or simplex and

redundant I/O Channels using TAs and signal conditioners

• Redundant Field Communication Modules (FCM2F10) for single mode fiber

communication to FCP280

• Up to two Field Device System Integrator Standard modules

(1 x or 2 x FBM232, 2 x FBM233) for Modbus TCP Communication

• Daisy chain from one enclosure to the next to reduce home run cables for

communication and power. Alternatively, the power output used to daisy chain an

enclosure can be used to provide power to a wireless field device access point

installed outside of the enclosure

• Up to two Fieldbus Isolator/Repeator modules for daisy chaining enclosures

using Copper (FBI200) or Fiber Optic cable (FCM2F10)

• 12-port fiber optic patch panel with STconnectors for terminating and distributing

fiber-optic cables for communication to the enclosure and wireless field device

access point

• Document pocket inside front door

• Door stoppers to help prevent the door from swinging or opening too widely

• 120 V AC, 230 V AC system supply

• Supports the Intelligent Commissioning Wizard, which significantly reduces

commissioning effort and shortens the time to plant start-up (see Field Device

Expert for HART Devices Control and I/O (PSS 41S-10FDMHRT))

Environmental Protection

The enclosure provides NEMA4X/IP66 environmental protection, allowing it to be

used in harsh locations.

Thermal Protection

Heat from the equipment mounted within the enclosure is convected naturally and is

dissipated by the exterior surfaces of the enclosure. For operating in ambient
