Segment Protectors Provide Single Location for the Terminator
Pepperl+Fuchs introduced its R2 FieldConnex Segment Protectors. This product family allows the segment protector to be disconnected while leaving trunk communications uninterrupted, and they 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. the 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. Each spur and trunk connector features built-in test lead connections for The company's 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.
