Rockwell Automation / ICS Triplex T8314C Trusted Fiber TX/RX Unit
A conformal-coated fiber transmitter/receiver used for Trusted system communications.
Product Profile
Rockwell Automation T8314C is the conformal-coated execution of the Trusted T8314 Fiber TX/RX Unit. The unit is not itself a safety-related module, but it is documented as interference-free for safety-related communication applications up to SIL 3.
The conformal coating meets MIL-I-46058C and IPC-CC-830 requirements and is UL-recognized. Hardware revision and system release compatibility must remain part of the maintenance record.
Technical Data
System Role
The optical interface supports communication while maintaining the Trusted system separation concept.
Conformal coating extends the environmental protection of the electronic assembly.
Release notes distinguish current, identical and compatible hardware revisions.
The certificate listing and the system release record must be checked together before service.
Compatibility & Service
- Record both the T8314C model and hardware revision from the label.
- Capture optical port assignments, fiber type, link direction and remote-node identity.
- Protect optical connectors from contamination and observe the approved cleaning method.
- After exchange, verify link state, node communication, diagnostics and every affected safety-system proof test.
Applications
- Trusted system fiber communication links.
- Safety-system architectures requiring an interference-free communications component.
- Harsh-environment cabinets where the conformal-coated C execution is specified.
- Controlled modernization where T8314/T8314C hardware revisions are mapped to the installed release.
FAQ
Does the T8314C itself execute a safety function?
No. It is documented as non-safety-related but interference-free, allowing its communication role within appropriately designed safety applications.
What does the C in T8314C identify?
It identifies the conformal-coated version; the coating is documented against MIL-I-46058C and IPC-CC-830 and is UL-recognized.
Why must the hardware revision be included with a T8314C order?
Release notes and certificates identify revisions separately, so the model alone does not prove compatibility with the installed Trusted release.
What optical details should be recorded before replacement?
Record port direction, fiber identifiers, connector condition, remote node, routing and the received link or diagnostic state.
Can a restored link alone close the maintenance job?
No. Review Trusted diagnostics, communication redundancy and all affected proof-test evidence before returning the system to service.
