Watch an in-depth demonstration of *groov* RIO with our on-demand webinar: [Introducing groov RIO, I/O for the IIoT™](https://www.opto22.com/support/resources-tools/videos/webinar-introducing-groov-rio). In about an hour, we'll walk you through all the features and benefits of *groov* RIO, followed by a live demo of *groov* RIO's configuration options and embedded software tools. As an added bonus, you'll also see how *groov* RIO elegantly integrates with [Inductive Automation's Ignition platform](https://inductiveautomation.com/solutions/iiot), bringing you closer to your digital transformation and IIoT project goals! [![WATCH WEBINAR](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/439485/408dfdec-5bb9-43e1-8171-1e6f0f126384.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/439485/408dfdec-5bb9-43e1-8171-1e6f0f126384) #### Thousands? I/O signal options are (almost) endless. You can configure thousands of unique field I/O combinations with one *groov* RIO unit! How is this possible? [We've documented how we got these results](https://www.opto22.com/products/groov-rio/thousands-of-field-i-o). Ready to explore the possibilities of *groov* RIO?
