Powered roller conveyors allow for zoned specific conveyors. A single motorized roller can drive up to eight idler rollers. Rollers are 90 VDC and include a drive card. Multiple rollers can be driven using a single drive card. As the name implies, power roller systems consist of a paint roller that has paint fed to it through a tube; the inside of the roller is filled with small holes, allowing the pumped paint to keep the roller head full so you don't have to reload.
