Segment Protectors limit current in fieldbus networks.January 15, 2008 -
Featuring trunk in/trunk out wiring T-connector, R2 FieldConnex® Segment Protectors can be disconnected while leaving trunk communications uninterrupted, and inherently prevent over-termination that can cause start-up and commission problems. Units provide IP20 protection with DIN rail mounting in 4, 6, 8, 10, and 12 spur configurations. They include removable terminals with retaining screws as well as LEDs for power, communications, and short circuit status indication.

Pepperl+Fuchs' New Segment Protectors Feature Unique Trunk In/Trunk Out Wiring T-Connector
Provides single location for the terminator, and allow segments to be expanded without disturbing the trunk
TWINSBURG, OH - Pepperl+Fuchs introduces R2 FieldConnex® Segment Protectors. The compact R2 family is particularly unique in that they allow the segment protector to be disconnected while leaving trunk communications uninterrupted, and inherently prevent over-termination that can cause start-up and commission problems. They are also designed to eliminate errors that can occur while connecting test leads for system diagnostics work.
R2 Segment Protectors provide IP20 protection with DIN rail mounting, in 4, 6, 8, 10 and 12 spur configurations. They feature removable terminals with retaining screws, as well as bright LEDs for power, communication and short circuit status indication. They are FM/cFM approved for Div 2/Zone 2 application.
"Being able to disconnect the R2 segment protector without disrupting trunk communications is a very significant benefit, as it allows users to add additional spurs to the segment at any time without having to shut down the entire system. R2 segment protectors also deliver improved start-up and commissioning compared with other segment protectors as they provide simplified wiring and eliminate the possibility of over-termination, as the terminator can only be placed in the single open trunk-out terminal," says Kristen Barbour, Pepperl+Fuchs Product Manager.
Each spur and trunk connector features built-in test lead connections for Pepperl+Fuchs' popular Mobile Advanced Diagnostics Module (ADM). This eliminates the potential of causing shorts from incorrect wiring while connecting test leads for system diagnostics work.
Segment protectors are current limiting devices that provide an additional layer of dependability to the fieldbus network. They isolate a single short and keep it from affecting the entire network. When the fault is repaired the segment protector automatically resumes operation of the spur to help make fieldbus segments extremely reliable.
