- Offshore platform safety systems (FPSO, fixed platforms)
System Compatibility
The T8312-4C is designed for integration within the ICS TRIPLEX Trusted TMR platform. Confirm compatibility with the following system components before ordering:
- Chassis / Backplane: Trusted TMR chassis (verify slot type and backplane revision)
- Controller Modules: T8100-series Trusted TMR controllers
- I/O Modules: T8400 / T8420 / T8431 series Trusted I/O
- Communication Modules: T8800-series Trusted network interfaces
- Power Supply: Trusted redundant PSU modules
- Engineering Software: Trusted Safety Manager (TSM) configuration tool
Selection Guide
Use the following criteria to confirm the T8312-4C is the correct module for your application:
- Step 1 — Identify your Trusted system revision: Check the chassis label and existing module part numbers to confirm TMR platform generation.
- Step 2 — Confirm adaptor type: The suffix “C” designates a specific adaptor variant. Verify against your system wiring diagram and I/O schedule.
- Step 3 — Verify channel count: The 7-Way configuration must match your field wiring termination requirements.
- Step 4 — Check firmware revision: Ensure the module firmware is compatible with your Trusted Safety Manager software version.
- Step 5 — Confirm SIL requirement: For SIL 2 or SIL 3 loops, use only OEM-certified original parts unless a formal MOC (Management of Change) process approves an alternative.

Replacement & Compatibility FAQ
Q: Can the T8312-4C be used as a direct replacement for the T8312-4?
A: The suffix “C” indicates a specific adaptor variant. While the base form factor may be similar, the adaptor type must be verified against your system wiring schedule. Contact us for a compatibility check.
Q: Is the T8312-4C compatible with Rockwell Automation Trusted systems post-acquisition?
A: ICS TRIPLEX was acquired by Rockwell Automation. Post-acquisition Trusted systems generally maintain backward compatibility, but firmware and chassis revision should be confirmed. We can assist with cross-referencing.
Q: Can I use a third-party equivalent in a SIL 3 application?
A: Substituting non-OEM parts in SIL-rated safety systems requires a formal Management of Change (MOC) process and functional safety assessment. Konmask.com strongly recommends using original certified parts for SIL 3 loops.
Q: What is the lead time for the T8312-4C?
A: Lead time depends on current stock. In-stock units ship within 1–3 business days. Contact us for real-time availability.
Q: Do you provide test reports or certificates of conformance?
A: Yes. Documentation is available on request for all supplied units.
Q: What warranty is provided?
A: All units carry a 12-month warranty. Extended warranty options are available — contact us for details.
