In 2014 I purchased two Time Activated Relay Controllers (TLR4x, Rev.A, ©2010). I used one of boards on a project for about 5 years and it severed me very well. The second board was kept as a spare and never put in the field. I now have a new project where I am considering re-purposing the boards and was curious what the overall expected lifetime of the battery might be? Both of these boards have been sitting on shelves for a number of years. From what I can tell the batteries cannot be changed…so I am debating whether its safe to put these boards back in service…or whether I need to consider updating/upgrading or tackling the project a different way.
Also, I am guessing I will need to update the firmware on the boards at a minimum…but are these boards otherwise still in production and being supported by NCD?
Any thoughts would be appreciated!
