Re: "DIN rail" or Not

Just to expand on Al's points. If you want Aluminum DIN rail this is the part number you can order from an Allen Bradley distrubtor. Such as Kendall Electric, Wabash Electric, etc.

Aluminum:
1492-DR5

Steel:
199-DR1

Also I would like to touch on one thing about these power blocks. Although most would agree that they aren't the best thing to use for robot/car type methodology in wiring applications, they ARE however given to all the teams by a "sponsor" Rockwell Automation, that wants you, a student and possible future engineer, to have some experience using their products. It's no different than receiving AutoDesk products. Allen Bradley is exposing you to products you'll use in Industrial Controls, A.K.A. Controls Engineering should you choose that path. The same goes for National Instruments, ironically a competitor to Rockwell Automation for industrial controls platforms. PLC verses PC based controls....anyway....sometimes you gotta step back and look at the big picture of why things change, they change because sponsors want to see this program grow, and they also want in return to see their products or services getting some exposure. It's not because someone is punishing us. But rather let's show appreciation for what we receive and thank the big fish sponsors for their donations.

Did you know that FIRST had a booth in Chicago at Rockwell's "Automation Fair 2007"? That was the first time I had heard of it. That's big exposure for FIRST at Automation Fair.

I think back when the Apollo missions had all these problems. The engineers dumped out a box of parts on the table and said "Ok this is what they have on the rocket to work with, let's figure out how to make an air filter using these parts". Thinking of using the power blocks in this way, it's what you have to work with, make the best of it, and thank Rockwell Automation for their donations.

disclaimer:
Do I use Allen Bradley/Rockwell Automation products now? Yes, I buy thousands of dollars each week... I consider myself an expert with Alllen Bradley PLCs (programmable logic controllers), a bit biased in the least, but I do appreciate what they have done for FIRST.
