DriveControl ZPA+4 is a new control mechanism that communicates with as many as four conveyor zones simultaneously to provide truly accurate zero pressure accumulation. The ZPA+4 control device is part of the DriveControl family designed specifically for 24VDC, 1.9-in. diameter Driveroll motorized rollers. The DriveControl ZPA+4 communicates with driver cards in each conveyor zone to move products with or without network control. The ZPA+4 continually sends and receives signals from each zone and instructs each driver card to turn on or off as movement is required.
