Channel-to-Channel Isolation & DCS System Protection
The 900TNF-0200 filler block terminal cover secures unpopulated module slots across ControlEdge HC900 and Experion Series C racks. Built with an EMI-shielded molded plastic structure, the cover prevents particulate contamination, accidental physical contact, and electromagnetic disturbance from affecting adjacent active cards handling 4-20 mA HART loop protocol signals. The unit maintains channel-to-channel isolation distances across backplane bus slots and supports uninterrupted hot-swap maintenance on adjacent operational I/O modules.
Frequently Asked Questions
Q: Does installing or removing the 900TNF-0200 cover require shutting down the rack power supply?
A: No, the passive snap-in cover is designed for online insertion and removal, allowing online maintenance without interrupting neighboring active I/O modules on the backplane.
Q: How does the cover contribute to system noise suppression in mixed signal racks?
A: The cover housing features integrated EMI shielding properties that block stray electromagnetic radiation from entering open slot backplane pin fields where 4-20 mA HART signals are routed.
Q: Is external power required for the terminal cover?
A: No, the 900TNF-0200 is a non-powered mechanical protection component designed strictly for physical slot enclosure and bus pin isolation.
Field Installation Guidelines
- Align the upper retaining tabs of the 900TNF-0200 cover with the target empty slot position on the rack chassis.
- Press the cover firmly into the slot until the snap-in latch mechanism engages completely with the rack frame.
- Ensure the cover sits completely flush with adjacent I/O modules to maintain continuous EMI shielding across the backplane faceplate assembly.
- Keep slot covers installed on all unpopulated positions to maintain proper convection airflow patterns within the control cabinet.
