Frequently Asked Questions

What is the difference between 3700 and 3700A models?
The 3700A version supports +6% voltage overrange capability for additional flexibility.
How does the triple modular redundancy work?
Three processors compare results and select the middle value for maximum reliability.
Can I use this module in non-Tricon systems?
No, it requires a Tricon chassis and specific backplane communication.
What happens if one channel fails?
The module continues operating using the two good channels without interruption.
Is special training needed for installation?
Basic knowledge of Tricon systems and the External Termination Panel is recommended.
