Frequently Asked Questions (FAQ)

1. What does “isolated I/O” mean in this module?

   It means each I/O channel is electrically isolated from the control system to prevent ground loops and protect against surges.

2. Can I configure the I/O channels individually?

   Yes, all 16 channels are user-configurable as either input or output.

3. Is the module compatible with both AC and DC signals?

   The field power supports both AC and DC, but I/O typically operates in DC voltage ranges.

4. How is the module mounted?

   It supports both DIN rail and panel mounting for flexible installation.

5. What protections are built in for harsh environments?

   The unit is designed with EMI/RFI shielding, thermal stability, and vibration resistance.

6. What is the max current per output?

   Each output channel supports up to 0.5 A.

7. What diagnostics are available on the module?

   Each I/O point has an LED for status indication and error diagnostics.

8. What systems can it connect to?

   It is designed for GE Genius I/O systems and compatible controllers.

9. What’s the response time for switching I/O states?

   Less than 10 ms in typical applications.

10. Is the module hot-swappable?

    While Genius I/O systems support hot swapping under certain conditions, always refer to GE’s safety manual for guidance.
