Channel Isolation and Rack Protection Features
The Honeywell 900RNF-0200 maintains the mechanical structure and isolation characteristics of unused redundant CPM rack positions. It slides directly into CPM rack slots and closes open positions without adding active electronic functions.
In addition, the filler plate provides shielding effectiveness above 40 dB and supports the original rack isolation rating. The module prevents exposed rack openings and maintains the intended physical separation between installed controller components.
The Honeywell CPM rack architecture uses modular slot positioning, therefore the 900RNF-0200 supports consistent rack assembly conditions when redundant processor positions do not require an RSM module.
Frequently Asked Questions
Q: Does the 900RNF-0200 contain active electronic circuits? A: No. The 900RNF-0200 is a passive filler plate component without processor, communication, or power conversion functions.
Q: Can the 900RNF-0200 replace a Redundant Switch Module (RSM)? A: No. The 900RNF-0200 is specified as a filler plate without RSM functionality. It only occupies and protects an unused CPM rack position.
Q: What installation condition should be considered when mounting the filler plate? A: The filler plate should be fully seated in the CPM rack slot to maintain mechanical alignment and rack isolation characteristics.
Field Installation Guidelines
Install the 900RNF-0200 only in designated Honeywell CPM rack filler positions.
Confirm that the rack slot is free of active modules before insertion.
Align the filler plate with the rack guide rails and apply uniform insertion force.
Avoid mechanical impact on the filler plate housing during installation.
Maintain standard cabinet grounding practices to preserve system electromagnetic performance.
Keep unused rack openings covered to prevent contamination and maintain enclosure conditions.
Verify the final rack assembly before controller power application.
