I’m looking at my ISOx16 relay module and trying to figure out how to make it work with my Panda II and later with a Cobra II. Haven’t found any doc on the product. Is there a manual/spec sheet? If not, here’s my thoughts and questions:
I count three terminals per relay (48 total). I’m guessing two of these go the load controlled by the relay, in my case 12VDC and ground. Which two are which and what’s the third for?
To control the relays, I plan on connecting 7 GPIO on the Panda to either an extender module connected to the end of the gadgeteer cable that goes to the relay board or what about the 20 male pins, arranged in two rows of 10, that stick up right behind where the cable attaches to the relay board? Can a female x female header be attached to either row of 10 pins to receive the wires from the Panda?
Finally, how do i control the 16 relays with 7 GPIO pins?
