Updated interactive website demo provides guidance for choosing sinking or sourcing modules for both groov and SNAP PAC systems.
Confusion around sinking and sourcing wiring is one of the most common causes of field issues in DC control systems. Get it wrong, and devices won’t turn on—or worse, you end up rewiring a panel that should have worked the first time.
But manufacturers label their DC outputs in different ways. We updated our interactive demo to make the concepts simple. It shows exactly how sinking and sourcing circuits work and helps you select the correct I/O modules for both your groov and SNAP PAC systems. Try it now!
The new online demo walks you through what sinking vs. sourcing means and the situations in which you'd use one instead of the other. And you can see which exact modules you'll need to select for your application—whether you're using a groov system or SNAP PAC.
You'll get step-by-step guidance and the option to download images of each step.
You might also find this short technical guide useful. It defines sinking and sourcing, shows you why to choose one rather than the other, and answers:
- When is it more cost effective to choose sinking over sourcing?
- What effect does an existing electrical panel have on your choice?
- What do you do if you have a mix of devices wired differently?
