FAQ

1. Why is the maximum inrush current 1.31 amps?
   It represents the short current drawn at startup and helps size the power supply correctly.

2. How does the 10/100 Mbps speed affect network performance?
   It ensures compatibility with devices that communicate at 10 or 100 Mbps for efficient data transfer.

3. What must be considered when using a 24 VDC power input?
   The supply must be stable and capable of handling both operating and startup inrush currents.

4. Does 4.6 watts power consumption matter for cabinet design?
   Low power reduces heat generation and helps maintain stable cabinet temperatures.

5. Why is 50/60 Hz listed?
   It indicates compatibility with standard industrial AC power systems.

6. How are the eight ports typically used?
   To connect PLCs, industrial PCs, operator panels, and remote I/O modules.

7. What are the benefits of copper RJ45 ports?
   They support standard Ethernet cables, widely available and easy to install.

8. Why is DIN rail mounting advantageous?
   It allows secure and space-efficient installation alongside other automation components.

9. Does the switch auto-detect connected device speed?
   Yes, it supports auto-negotiation to match the device speed automatically.

10. How does the switch maintain stable communication under traffic?
    It isolates traffic per port and buffers incoming data to prevent collisions.
