UniPro™ Custom Control Panels with Programmable Logic

The UniPro™ Valve Closure System is available with standard relay logic controls panels, as well as control panels with programmable logic. Either control panel is a separate stand-alone unit that can be taken offline without affecting other control panels. A communication cable links each panel. In place of pilot lights and switches, the operator interfaces with the panel via the screen display. This updated panel configuration gives the end user flexibility to adapt the control panel if the architecture of the unloading system needs to be modified.
