Motor-controller Zero-Pressure Accumulator (MPZA) conveyor makes pallet accumulation simple and reliable by eliminating pneumatic clutches, zone-to-zone chains and PLC controls. Conveyor is standard equipped with the Allen-Bradley Bulleting 22ZC plug-and-play zone control boxes. With a minimum profile height of six inches, a single MZPA conveyor can be configured in up to 12 zones in lengths of four to six feet. All controls, photo-eyes and motor starters are self-contained, pre-mounted and pre-wired before shipment. The 24 VDC power supply is included in the master control box. Programmable time delays before zone advance, a "sleep mode" and signals for flow control logic are all standard. A wash-down version is available for pharmaceutical and food applications.
