Foxboro PSS 21H-2X62 B4 G62 and G72 Tricon System and Termination Enclosures

The G61enclosure is available as a vented or sealed enclosure. It can be configured

with:

• Uptosevenvertical DIN rails for mounting of Triconex termination devices and

additional customer-supplied terminal blocks for marshalling

• Redundantpowersupplies (480 W or 960 W 24 VDCpower supplies) for field

power

The G61vented enclosure is a free-standing, floor mounted unit with an IP43/55

rating for location in mild (ordinary) environmental areas.

The G61sealed enclosure is a free-standing, floor mounted unit, with options for

either an IP55 or IP66 rating for location in harsh environments.

Sealed enclosures with an IP66 rating provide a higher level of protection from

airborne contamination.

NOTE: In regions that require EMC compliance, you must order the EMC

compliance option if the Triconex termination devices for Tricon modules SMM or

SRXMwill be installed in this enclosure. Without these termination devices, the

enclosure already fulfills the requirements for EMC compliance.

An optional door intrusion monitoring switch is available for each door on this

enclosure. Each switch is prewired to a set of alarm status terminal blocks.

The G61enclosure can be installed bayed or adjoined to other Triconex enclosures to

maximize the use of floor space and ease of cabling. The enclosures can be bayed

together using third-party kits.

This enclosure and its configurations have been tested and qualified by Foxboro for

use with the Tricon equipment.
