A new control system for connecting powered roller control zones from Holjeron requires less installation time, field wiring and cabling. Holjeron is a subsidiary of Matthews International Corp.

The conveyor control system consists of four different products.

Driver modules drive and protect motorized rollers and have no additional control logic. Most include connections for the zone sensor, reducing the need for sensor inputs on remote I/O.

Zero pressure accumulation (ZPA) modules have built-in logic to perform single zone ZPA, and may or may not directly drive a motorized roller. They also include connectors for zone sensors.

Controllers are designed to be combined with driver modules to perform multi-zone ZPA or combined with ZPA modules to do merges, diverts and transfers. Controllers may also have a network connection for linking control systems to a host controller. Interfaces tie systems and equipment together but don't do any direct zone control.
