Review on 🏠 UCTRONICS DC 12V Programmable Time Delay Relay Module with LED Display for Smart Home Automation by Pamela Johnson

I have a SiriusXM Radio Tour in my company car. It can record up to 30 minutes later than live, and it also takes some time to load when it's on. Initially, the power would cut off when the car was turned off, erasing everything that was being recorded and requiring you to wait until you could hear the music again the next time you started the car. I start and stop a lot on the maintenance route. Hardwiring the radio to a permanent battery wasn't ideal either, as it could drain the battery if I forget to unplug it at the end of the day. There is a relay that turns off the radio after a predetermined time after the car is turned off. It took some trial and error to find the correct programming mode and I use mode 10. Mode 10 keeps the relay on constantly when the auxiliary circuit is on and starts a timer set for 2 hours after the accessory is off became. , then it turns off the relay when the timer expires. I ended up setting T1 to 7200 seconds, setting T2 to 200 but not using it. and the NX setting I had to set to 120 for T1 to count seconds, any other NX value like 60 would result in T1 ending in less than a second even if it's two hours later. small plastic case as it is an exposed circuit board and may short circuit to a metal object in the car. also cancels the timer and keeps running if I turn the accessory back on before 2 hours is up, and starts a new 2 hour timer when the accessory turns off again. Exactly what I wanted from him.
