Compatible Replacement & Equivalent Models
When the FS-TSDI-16115 is unavailable or end-of-life, the following models may serve as functional equivalents or replacements depending on your system configuration. Always verify compatibility with your FSC system revision before substitution.
- FS-TSDI-16110 – Earlier revision of the same SDI termination assembly; verify firmware compatibility
- FS-TSDI-16120 – Higher-channel-count variant; may require chassis slot reconfiguration
- FS-TSAI-16115 – Safe Analog Input FTA; different signal type, not a direct replacement but used in mixed I/O panels
- Triconex 3703E (Schneider Electric) – Third-party SIL-rated digital input module; requires engineering assessment for cross-brand migration
- HIMA F3DI 16/8 01 – HIMA SIL 3 digital input module; alternative for greenfield projects
Note: Cross-brand replacements require full HAZOP/SIL verification. Contact our technical team for migration support.

System Compatibility
The FS-TSDI-16115 is designed exclusively for the Honeywell FSC (Fail-Safe Controller) / Safety Manager platform. Confirm the following before ordering:
- FSC chassis generation (SM, SM-SC, or legacy FSC)
- System firmware version (consult Honeywell release notes for FTA compatibility matrix)
- Slot assignment and I/O module pairing (FS-SDI series processor module required)
- Cabinet wiring standard (IEC or ANSI terminal labeling)
Selection Guide
Use the table below to select the correct FTA for your Honeywell FSC digital input requirements:
- 16-channel SDI, standard voltage, SIL 2/3 → FS-TSDI-16115 ✓ (this model)
- 16-channel SDI, NAMUR sensor input → FS-TSDI-16115N (NAMUR variant)
- 8-channel SDI, high-density → FS-TSDI-08115
- 32-channel SDI, multiplexed → FS-TSDI-32115 (where available)
- Safe Analog Input (4–20 mA) → FS-TSAI series
- Safe Digital Output → FS-TSDO series

Replacement & Compatibility FAQ
Q: Can I use FS-TSDI-16115 to replace an older FS-TSDI-16110?
A: In most cases yes, but verify the FSC firmware version supports the newer FTA revision. Honeywell’s compatibility matrix (available from your local Honeywell office) should be consulted.
Q: Is FS-TSDI-16115 compatible with the Honeywell Safety Manager SC?
A: Yes, the FS-TSDI-16115 is compatible with Safety Manager SC platforms. Confirm slot and wiring configuration with your system integrator.
Q: Can this FTA be used in a non-Honeywell safety system?
A: No. This module is proprietary to the Honeywell FSC/Safety Manager architecture and cannot be used as a standalone or cross-platform component.
Q: Do you supply the matching SDI processor module?
A: Yes. We stock a range of Honeywell FSC I/O processor and FTA modules. Contact us with your full BOM for a complete quote.
Q: What is the difference between FS-TSDI and FS-TSAI?
A: FS-TSDI handles discrete/digital inputs (on/off signals), while FS-TSAI handles analog inputs (4–20 mA, thermocouple, RTD). They are not interchangeable.
