We've just made it a lot easier to pick the input/output modules you need.
Our new SNAP I/O Selector lets you start with the signal type and see all the Opto 22 SNAP I/O modules that match.
You can start at the left and choose analog, digital, serial, or special-purpose modules.
Or start in the middle and choose temperature, current, voltage, pH/ORP, or other signals. The selector leads you through module types, signal types, and number of channels to find the exact module to fit your needs.
