よくある質問 (FAQs)

1. What types / input signals can the 621-3560 handle?
   The module is designed for either analog or digital inputs, supporting current (4–20 mA) or voltage (0–10 V) signals depending on the system configuration.

2. Can I use this module in both TDC 2000 and TDC 3000 environments?
   Yes, the 621-3560 is cross-compatible with both systems, making it ideal for hybrid control environments or system migration.

3. Does the module support channel isolation?
   Yes, the module includes electrical isolation between input channels and from the system bus to prevent signal interference.

4. What diagnostics are available on this module?
   LED indicators are provided for each input channel to monitor status, signal activity, and fault conditions.

5. Is hot-swapping supported with this module?
   In most chassis configurations, the module can be replaced without shutting down the entire system, minimizing downtime.

6. How does this module perform in high-humidity environments?
   The 台 is rated for up to 95% relative humidity (non-condensing), suitable for most industrial settings with proper enclosure protection.

7. Can I integrate this module with a newer HPM (High Performance Process Manager) system?
   Yes, via TDC-compatible I/O interfaces, the module can be used within hybrid systems including HPM or APM configurations.

8. Are there any restrictions on installation locations?
   It must be installed in an appropriate enclosure (e.g., control cabinet) with adequate airflow and ambient temperature control.

9. What is the update or scan rate / the module?
   The module typically supports update rates faster than 100 ms per input, allowing real-time process feedback.

10. What noise rejection characteristics does the module /fer in industrial environments?
