Information
Overview
Manuals
Common Applications
Product Precautions
At the remote end of the RXM link, TRICONEX 4201N receives and returns I/O-bus traffic over the assigned optical channels.
- Serves as the remote module in a 4201-3 RXM set
- Uses point-to-point fiber-optic communication
- Supports a published separation of up to 7.5 miles (12 km)
- Operates in an RXM chassis with two power modules and up to six I/O slot sets
Each remote RXM chassis must contain at least one I/O module and retain the documented transmit and receive channel assignments. Installation acceptance should confirm cable identity, ST connector engagement, remote-chassis power and the expected extender indicators before process I/O is released.
Important Notice: Confirm the complete 4201N identity, installed system record and approved companion hardware before replacement or commissioning.

2
Place the controller and affected process function in the approved safe maintenance state.
3
Verify the documented system version, companion hardware and interface assigned to 4201N.
4
Isolate the applicable controller and field energy in accordance with the approved procedure.
5
Inspect connectors, keys, cable assemblies and mechanical retention before installation.
6
Install 4201N only in the recorded location without changing the approved architecture.
7
Restore power under control and confirm the specified indicators, communications and diagnostics.
8
Document the final identity, configuration and functional acceptance results before release.
Technical notes
For 4201N, the verified dataset records qualified designation as 4201N and standard-model mapping as 4201. These values must be applied only after the complete installed marking, cabinet record and approved system architecture have been reconciled.
