5B or 7B
If you're familiar with 5B signal conditioners, you might not be familiar with 7Bs, or if you've used 7Bs you may not know about 5Bs! Because Dataforth manufactures both, here in Tucson, Arizona, we know this is true... once selected, engineers tend to stay with one or the other, SCM5B or SCM7B!

However, the '7B Engineer' can find many more I/O functions available with 5Bs and the '5B Engineer' might find 24Vdc power supply for 7Bs more convenient on some applications... just to mention a couple of different features!

So, how do all the specs, prices, and types of functions compare?

See the table on this page or, see a more formal, single page comparison table (48kb pdf).
