Triconex 4201N is the remote-end module in the nuclear-equipment cross-reference for the standard 4201 RXM. It forms the remote side of the multimode Tricon I/O extension arrangement and must be paired with the correct primary-side equipment and approved chassis configuration.
The optical link uses 850 nm multimode transmission through 62.5/125 micrometre fiber and ST connections. The published 375 kbps rate describes I/O communication. Maximum distance is 2 km only when the total attenuation, connector and splice losses satisfy the applicable optical power budget.
Before changing the remote module, preserve the transmit/receive mapping, channel labels, remote-chassis identity and measured optical performance. Confirm local chassis power separately from the optical link. Order the exact 4201N identity and distinguish an individual module from the 4201-3N set.
| Manufacturer | Triconex |
|---|---|
| Model | 4201N |
| Manufacturer cross-reference | Nuclear 4201N corresponds to standard 4201 |
| Module role | Remote-end RXM |
| Set distinction | 4201N is a module; 4201-3N is the listed set |
| Associated primary role | 4200-series multimode primary RXM arrangement |
| I/O communication rate | 375 kbps |
| Fiber core/cladding | 62.5/125 µm multimode |
| Wavelength | 850 nm |
| Maximum link length | 2 km, conditional on total optical losses |
| Optical connector | ST bayonet |
| Typical optical budget | 15 dB |
| Worst-case optical budget | 8 dB, including connector losses |
| Fiber path arrangement | One transmit and one receive fiber per channel |
Maintain remote-chassis identity, fiber polarity and local power arrangements. Check 4201N assembly qualification and optical performance before returning the link to service.
Trace each channel from the approved primary-to-remote drawing and verify transmitter-to-receiver continuity. Preserve channel labels so crossed fibers or mixed channels are not mistaken for a failed 4201N.
The guide identifies ST bayonet connectors. Inspect the seating and locking arrangement and follow the approved optical-cleaning procedure; a connector that appears inserted may still have excessive loss.
No. The corresponding remote RXM specification is 62.5/125 micrometre multimode at 850 nm. Confirm the installed cable markings before selecting replacement optical hardware.
No. Distance is only one contributor to attenuation. Include splice and connector losses in the complete power budget and verify the measured link after any fiber repair.
The manufacturer distinguishes primary and remote RXM roles. Preserve the designated role and set arrangement; matching fiber connectors do not establish interchangeability.
No. Record and check the individual channel paths and system diagnostics. A single indication does not verify every transmit/receive pair or the complete remote I/O configuration.
Keep the route, core allocation, end labels and measured loss for active and designated spare fibers. That record allows an approved fiber change without losing channel identity.
No. Optical continuity and local power are separate checks. Verify the remote chassis supply indications and system diagnostics together before concluding the remote equipment is ready.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
