FAQ (Frequently Asked Questions)

Q: Is the TRICONEX 3664 hot-swappable?A: Yes, but only in Tricon v10/v11 systems. Hot-swapping is allowed, but isolate field loads first to prevent voltage spikes.

Q: Can it drive 110VAC loads directly?A: No. The module is 24VDC only. Use interposing relays for AC loads to avoid damage.

Q: What happens if a channel fails?A: TMR voting isolates the faulty channel; the module continues operating with the remaining two channels. It logs a fault alarm for maintenance.

Q: Does it require external fuses?A: No. The 3664 has self-protecting circuitry per channel. External fuses are not needed and may interfere with diagnostics.

Q: What’s the difference between 3664 and 3674?A: The 3664 is 24VDC; the 3674 is 48VDC. They share the same pinout and form factor but have different voltage ratings.

Q: What warranty is included?A: 12-month manufacturer warranty covering material and workmanship defects. Defective units are replaced at no cost if returned within the warranty period.

Q: Can I use it in non-Tricon systems?A: No. The 3664 uses a proprietary backplane interface and TMR logic specific to Tricon SIS platforms. It is not compatible with other DCS/PLC systems.
