FAQ

1. What types of analog signals are supported by the MU-PAIH02 module?

   The module supports 4–20 mA, 0–20 mA, 1–5 V, and 0–5 V input signal types.

2. Is there electrical isolation between channels?

   Yes, each channel is individually isolated to prevent cross-talk and ground loop interference.

3. Can the module detect a broken sensor loop?

   Yes, it has built-in diagnostics for open loop and out-of-range conditions.

4. What is the resolution of each analog input?

   The input resolution is typically 12-bit, providing fine signal granularity for control purposes.

5. Does the module support HART communication?

   No, MU-PAIH02 is designed for standard analog signals and does not natively support HART protocol.

6. Can the module be replaced while the system is powered?

   Yes, hot-swap is supported when used in a redundant or fault-tolerant I/O chassis.

7. How frequently does the module update input values?

   Input channels are typically scanned every 500 milliseconds.

8. Is the module suitable for safety-critical systems?

   It can be used in high-reliability environments, but safety integrity level (SIL) must be validated at the system level.

9. Does the module require external power?

   No, power is supplied through the IOTA/backplane connection.

10. Can multiple MU-PAIH02 modules be used in a single system?

    Yes, multiple modules can be installed to scale analog input capacity as required.
