4. FAQ — Ten Q&A (Strict QA Format, Non‑AI‑Style)

Each paragraph ends with a blank line, as requested.

Q1. How is this module mounted in the rack?
A. It slides into a dedicated slot on the backplane and locks with a front latch—no tools needed.

Q2. Can the input and output channels be used simultaneously?
A. Yes, all four inputs and four outputs can operate at the same time without conflict.

Q3. What type of signal range does it support?
A. It supports both 0–10 V and 4–20 mA signal types, configurable per channel.

Q4. Is power consumption significant?
A. No, it consumes about 5 W when fully loaded, sourced through the rack backplane.

Q5. Are the LEDs useful when module is powered down?
A. No, LED indicators require module power—they do not display status when unpowered.

Q6. Does it require calibration?
A. Modules are factory‑calibrated; field recalibration can be done via calibration software as needed.

Q7. How does it communicate diagnostic errors?
A. Fault LEDs light red for channel errors, and the rack controller logs a diagnostic flag.

Q8. Can the module operate in hot ambient environments?
A. Yes, rated to reliably operate up to +70 °C, suitable for most industrial environments.

Q9. Can I hot-swap this module?
A. No—live replacement is not supported; power must be off before insertion or removal.

Q10. What is the expected lifespan of this module?
A. With normal operation, it typically lasts over 10 years in field service before replacement is needed.
