Have you discovered our secret cache of SVG images?

You can use these free images in your groov mobile operator interface or in other places where SVG (scalable vector graphics) files are supported.

Bring them into your interface and make them the size you need. Because they're SVG, they automatically scale, so they look good whether they're on a monitor or a smartphone.

If you've used Opto 22 products for a long time, you may very well have some colorful G4 digital I/O modules in a panel somewhere. They were probably installed back in the 1990s.

Still reliably monitoring sensors and activating outputs, these G4s are likely the workhorses of your automation system. Why would you ever want to replace them?

We talked about sinking and sourcing in a previous OptoNews tech tip.

But it's a subject that causes a lot of confusion, so it's worth revisiting.

Sinking and sourcing basically refer to the two methods of wiring a digital DC circuit.
