Frequently Asked Questions (FAQ)

• Q: What input types does the Honeywell 900A01-0002 support?
  A: It supports thermocouple, RTD, resistance, voltage, mV, mA, and slidewire inputs on a per-channel basis.
• Q: Does adding more analog modules increase scan time?
  A: No. All analog input modules process in parallel, so scan time remains unchanged.
• Q: How do I know if the 900A01-0002 module is working properly?
  A: A green blinking LED indicates normal scanning. Red LED means diagnostic conditions exist.
• Q: What happens if a sensor fails on a thermocouple input?
  A: The module provides both a maintenance warning and a sensor failure signal to alert operators.
• Q: Can I configure each channel for a different input type?
  A: Yes. Each of the 8 channels is independently configurable for your specific sensor type.
• Q: Is the 900A01-0002 compatible with the HC900 controller?
  A: Yes, this card is designed specifically for the Honeywell HC900 controller series.
