4X/IP66 rated

◦ ClassG3(harsh) environment

◦ ATEX

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

◦ 64SimplexI/O

◦ 64RedundantI/O

◦ 48Simplexand16Redundant I/O

• Upto16Universal Standard I/O modules (8 x FBM247. 16 x FBM248. or

4 xFBM248and6xFBM247)thatsupport 64 simplex, redundant, or simplex and

redundant I/O Channels using TAs and signal conditioners

• RedundantField Communication Modules (FCM2F10) for single mode fiber

communication to FCP280

• UptotwoField Device System Integrator Standard modules

(1 x or 2 x FBM232. 2xFBM233)for Modbus TCPCommunication

• Daisychain 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

• UptotwoFieldbus 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

• Documentpocket inside front door

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

• 120VAC,230VACsystemsupply

• 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

temperatures up to 55° C (131° F), natural convection is supplemented by two

redundant fans that circulate air within the sealed enclosure.

The fans and temperature within the enclosure are monitored by the Enclosure

Monitoring Unit (EMU) that provides a diagnostic alarm on fan deterioration or

enclosure over temperature.

Leave a minimum of 150 mm(6 in) space between adjacent cabinets or a cabinet and

a wall, to allow the flow of air to cool the cabinet.
