I have a 44 year old DIY low voltage lighting system based on TTL circuits that is still going strong. I want to update this system to include smart monitoring.

I have 2 questions.

1) What is the life expectancy of the kc868-a64?
2) What is the duration of your products before they go out if production?

1. It's difficult to specify a specific time, but it usually won't be damaged because there are no relays or any mechanical moving components on the KC868-A64.
2. 24 hours aging test

I guess my question 2 was not clear enough.

2) What is the time period between the introduction of a new product and when it is replaced or obsolesced?

The product will not be replaced, only new models will be launched, but there will be no too many hardware changes with KC868-A64, because it's 64 channel version.
