Frequently Asked Questions (FAQ)

• Q: Can the Honeywell MU-PAIL02 connect directly to a 2-wire transmitter?
  A: Yes, but the transmitter needs an external power supply. The module only provides the input interface.
• Q: How does open thermocouple detection affect the sampling rate?
  A: Enabling this feature reduces the scan rate from 8 to 4 samples per second per channel.
• Q: What are the CMV and dielectric withstand ratings for the MU-PAIL02?
  A: CMV is 250 Vac rms or ±250 Vdc; dielectric withstand is 1500 Vac rms or ±1500 Vdc.
• Q: What happens if the input exceeds -20mV to 5.5V?
  A: Exceeding this range may damage the module. Always keep signals within this limit.
• Q: What is the difference between hardware and software accuracy?
  A: Hardware accuracy applies to voltage/current inputs; software accuracy refers to thermocouple temperature conversion error.
• Q: Does the MU-PAIL02 support both 50Hz and 60Hz line synchronization?
  A: Yes, it covers a range of +3% to -6% for both frequencies via hardware synchronization.
