Spike (relay) module pin out

[coreyjon]

My goal is to make a small device to drive the spike relay module for troubleshooting the robot. Not that we have to do alot of that or anything . We have a pwm signal gen for the same reason, although as you know, spikes dont take in a analog pwm signal, they use a digital signal. My hypothesis is that the black wire is ground, as it is in most applications, and the other two wires control the relays output, one being foward, the other being reverse. I don't plan on doing anything fancy, I understand that the spike can handle an input voltage up to 15VDC (correct me if im wrong) but I plan on using 2 small 6 volt batteries (or some configuration to get me close to 12VDC). A lot of writting for something simple, I know, but I would rather get it right the first time, I could guess and check, but without a spike module in front of me, I would have to wait until I get down to atlanta, and I would like to have this tool ready for use by then.

Note: I looked on www.innovationfirst.com first and couldnt find the pin out. So I did look before asking on the forum.
