Compatible Replacement & Equivalent Models
When the T9481 is unavailable or end-of-life, the following models may serve as functional replacements depending on your system configuration. Always verify backplane compatibility and firmware revision before substitution.
- ICS TRIPLEX T9480 – 2-channel isolated AO; suitable for lower-channel-count applications
- ICS TRIPLEX T9482 – 6-channel isolated AO; upward-compatible for expanded I/O needs
- Rockwell Automation 1756-OF8 – ControlLogix 8-channel AO; requires gateway/adapter for Trusted™ integration
- Hima F3AO 8/4 – 8-channel SIL 3 AO module; cross-platform alternative for SIS upgrades
- Triconex 3805E – Tricon AO module; considered in full-system migration scenarios
Note: Cross-brand replacements require engineering review. Contact Konmask.com for compatibility assessment.

Selection Guide
Use the following criteria to confirm the T9481 is the correct module for your application:
- Channel Count: Requires exactly 3 isolated AO channels → T9481 ✓ (choose T9480 for 2-ch, T9482 for 6-ch)
- Signal Type: 4–20 mA current loop or 0–10 V voltage output required → T9481 ✓
- Safety Integrity Level: SIL 2 or SIL 3 loop → T9481 ✓
- Platform: Existing Trusted™ TMR system → T9481 ✓ (non-Trusted™ systems require migration planning)
- Hot-Swap Requirement: Online replacement without process interruption → T9481 ✓
- Budget vs. Lead Time: If OEM lead time is critical, Konmask.com stocks tested surplus units — contact us for availability

Replacement & Compatibility FAQ
Q: Can the T9481 replace a T9480 directly?
A: Not directly — the T9480 is a 2-channel module. The T9481 adds a third channel. Slot and wiring changes are required; consult your system integrator.
Q: Is the T9481 compatible with the latest Trusted™ firmware?
A: Compatibility depends on your controller firmware version. Konmask.com can provide the firmware matrix upon request.
Q: Can I use a T9481 in a non-TMR (simplex) Trusted™ configuration?
A: Yes, the module can operate in simplex or duplex configurations, though SIL rating will be reduced accordingly.
Q: Do you supply test reports with the module?
A: Yes. A functional test report is included with every unit. Full FAT documentation packages are available on request.
Q: What is the typical lead time for a new OEM unit?
A: OEM lead times vary (typically 8–20 weeks). Konmask.com maintains surplus stock for immediate dispatch — contact us to check availability.
