FAQ
1. What is the primary technical difference between SBT01 and SBT02 versions?
The SBT02 version is optimized for enhanced isolation performance and extended noise imm台y compared to the SBT01.
2. Can multiple NFSB100-S50/SBT02 modules be connected in series?
Yes, cascading is possible, allowing longer distances, though system design must ensure signal timing integrity.
3. What type / electrical isolation does it provide?
It uses galvanic isolation to prevent signal interference and protect devices from surges.
4. Is the power supply redundant-capable?
It supports a single 24 V DC supply, but can be integrated into redundant system power designs externally.
5. How does the module regenerate bus signals?
It reshapes and re-amplifies signals, restoring proper voltage levels and timing for error-free communication.
6. What is the recommended maximum number / repeaters in one segment?
Typically, up to 3–4 modules in a single communication path, depending on network design.
7. Does it support monitoring or diagnostic features?
Yes, it includes internal status indication to monitor communication health and power conditions.
8. What kind / cabling is recommended for optimal performance?
Shielded twisted-pair industrial bus cables are recommended for noise imm台y and long-distance performance.
9. Is the device compatible with redundant communication paths?
Yes, it can be configured in redundant paths for higher system availability.
10. Can it be used in mixed-vendor networks?
It is designed for Yokogawa systems, but may work in mixed networks if bus protocol compatibility is ensured.
