Electrical Control Panel for Local Asphalt Plant
AMPS Industrial Controls Corp designs and builds control panels for a wide variety of industries but, like most companies, we have a handful of markets where we’ve focused more energy than others. Because we’ve had a very good, long-term relationship with a local asphalt production company, one of those industries is paving and material handling.
It seems like they are expanding or renovating or improving something in one of their plants each spring and they call on AMPS to handle the control panels. Oftentimes it’s a retrofit and we build the control panel to fit into a tight existing space or utilize some of their existing equipment. Other times they completely renovate the entire system and upgrade manual controls to a more modern, PLC-based system with operator interface (oftentimes a touch-screen PLC from Unitronics). We are happy to work with them in either situation, of course.
This spring the need was to upgrade the DC motor controls on an existing line in one of the asphalt plants. Simple control, no need for a PLC in this case. In fact, our control panel didn’t have any buttons, switches or speed pots at all. The customer supplied the analog speed reference signals and our panel was, more or less, a power control panel for the DC motors. As always, it’s our responsibility to ensure a safe panel with proper fuse or circuit breaker protection. We also design the system for maximum reliability by using the appropriate control components. The heart of this system is six DC motor controllers from KB Electronics.
This electrical control panel was completed in June, 2012 and installation should take place in early July. We trust it will serve as a reliable control panel for many years to come, providing asphalt for road projects all over northwest Ohio.
