Good day to all. My business partner is looking for someone that has used AB HMI=20 panels to talk to AB temperature controllers. Just looking for some=20 advice to begin with, probably ending up with that person doing a=20 fairly simple project with said HMI / MMI panel and temp controller. We build control systems for Industrial Ovens using Catalytic=20 heaters. One customer wants a fancy temperature controller for the=20 system, capable of holding several "recipes" for both temperature and=20 blower VFD speed. We are looking at some stuff that Watlow makes but=20 the end user uses mostly AB equipment and would prefer to stay with=20 that if possible. As far as I know, the temperature profiles are stable - they don't=20 involve ramp or soak times. Just set the temperature to some=20 set-point and keep it there. Same with the re-circulation blower=20 speed - just set a value (open loop). The requirement for setting=20 the conveyor speed has not been discussed (yet) but is possible. Our modulating-valve control module takes a 4-20mA input or a 0.25 -=20 1.25V control input for controlling the gas flow valves. Obviously,=20 our 0.25 - 1.25V control input can be scaled to whatever is=20 needed. The VFD can take either 4-20mA or 0-10V control input. Interested people can contact me directly at dwayner@planet.eon.net=20 .. This is a paying gig . One final note: I'm assuming that Allen Bradley is probably among the=20 most expensive gear available. Although this particular customer is=20 requesting AB, I can see that other Industrial Oven customers would=20 also like to have this kind of functionality - but at a lower=20 price. If anyone can suggest other products that can do the same=20 thing for less money than AB would charge, we would very much like to=20 hear about it. That can include Watlow, Automation Direct, or whoever.
