• Protection against harsh environments and hazardous locations:
◦ NEMA
®
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.
