The ‘Z’ card provides self-contained intelligence to control accumulation in four conveyor application zones, including any combination of straights, merge, divert or transfer. It interfaces to all Interroll RollerDrive products – both brushed and brushless solutions – enhancing the control capabilities of virtually any conveyor application. It offers optional control functionality via a Canbus network interface for high-end integration. It is also available in an IP54 enclosure for relevant industrial applications. A standard package includes a cable assembly kit to support the interconnect between the RollerDrive, photo eyes and the Z card for ease of installation.
