Thanks,Hi Jraef, Sorry to bother you, but I'm the guy that was asking about the variable speed control for farm livestock fans. I appreciate your replies and
posts. My last question is the product from Grainger that you suggested is 110V. Will this work on the 220V motor arrangement???
Thanks again for any help!!

Hi Jraef,
I bought the Allen-Bradley 1333 for $100. I also got a Baldor 1 Hp motor. The 1333 has 30 programmable
options. What I can't change is the switching frequency. I got the 1333 so that I can replace the logic
board with my new design based on a NXP LPC2925 (ARM 9).
If you ever make it up to Sunnyvale it is worth visiting HSC Electronics. Outside the building they often
have a dollar cart, every item is a dollar. Last Saturday I bought a Omega Temperature Controller
DP41-TC for $13.84. Brand new in the box. New models of this type sell for $570. They have lots
of test equipment and discrete parts. Been going there since my college days at UC Berkeley. -
