Hi Folks!
I'm very new at this and my head is already overloaded with information! I would appreciate your help with a (hopefully) easy wiring question..
I purchased a 5 Volt relay board on an auction site that I think is appropriate (it is active high).
I plan on powering it with a seperate 5 V wallwart power supply to the DC+ and DC- terminals on the relay board.
Is it as simple as connecting the TTL1 output from the CAI board to the CH1 input on the relay board?
I do not connect the GND from the CAI board to anything, right?
(btw, the relay will be used to control a circulator in a solar hot water system)
Thanks in advance!
