Hi,
I'm trying to use an 8 IO board to switch on some lv Led light strips. the led strip lights ok when connected directly to the battery.
i;ve got a 12volt battery, being charged by a small solar panel through mppt regulator. the battery is then connected to input 1 on the board, and i've got a small led string (about 2W) connected directly to the output on common/no connections. the relay seems to be permanently energised as soon as i connect the battery to the input 1. the Led light string doesn't come on and there isn't 12 volts appearing on the output. at one stage I am sure I saw 5v there, but i might have been hallucinating it was a long hot day sitting in the sun.
I can toggle the relay states of the other relays using software and the led beside the relay comes on, but I cannot toggle the output 1 off or on using sotware.
Any ideas where I am going wrong?
John
