Frequently Asked Questions (FAQ)
1. Can I use the 900G32-0001 with a non-Honeywell PLC?
No, the Honeywell 900G32-0001 works exclusively with the HC900 controller. Its backplane communication protocol is proprietary to Honeywell.
2. What is the maximum input frequency for this digital card?
The 900G32-0001 handles standard DC ON/OFF signals. It is not designed for high-speed counting. For pulse inputs above 50 Hz, use a dedicated counter module.
3. Does this module support hot-swapping in a live rack?
No, the Honeywell 900G32-0001 does not support hot swapping. You must power down the entire HC900 chassis before removal or insertion.
4. What happens if I apply 120 VAC to a channel?
Applying 120 VAC will permanently damage the 900G32-0001. The module accepts only 10 to 32 VDC signals. Always double-check your field wiring before power-up.
5. How do I check if my Rev C board is faulty?
Use the HC900 control builder software. Monitor the input status table for each channel. A constant 0 or 1 with no field change indicates a potential input failure on the 900G32-0001.
