Sorry for the title it was the only way i could think to write what i wanted. I am asking the general audience here some questions.
Right now i am developing an application that uses a camera, the camera is attached to a PC, now when certain events occur i want to have the PC give an output signal or maybe signals.
I have been looking at SainSmart, ICStation, Numoto, and they each have a 4 relay module that plugs into USB port. There is probably more options out there than these 3 but these three were the ones i found on amazon.
So I am basically asking if anyone has used such an item? If they didnt use one of the ones listed what ones did they use?
Where did they purchase such item?
How they would rate the item?
What other options are available and are recommended by the PLC community?
Here are the links for the various parties listed above:
http://numato.com/4-channel-usb-relay-module.html
http://www.sainsmart.com/sainsmart-...for-automation-robotics.html#customer-reviews
One of the things is that each of these seems to be overseas since i live in USA. Was hoping to find something a bit more local.
