The ZoneLink® ZPA Module directly drives a Holjeron Microroller™, providing the control logic for single zone Zero Pressure Accumulation (ZPA).

The ZoneLink ZPA Module can also be configured to operate in four other control modes: high-throughput singulation mode (zero pressure), train mode (low pressure), slave mode and manual mode.

Zone-to-zone communication is accomplished via Holjeron’s innovative connection method, ZoneLink. Using standard category 5 patch cables (RJ-45), a “ready” signal from the ZPA Module tells the upstream zone that it is ready to receive a unit. A “sending” signal from the ZPA Module tells the downstream zone that it is sending a unit.

To streamline installation and wiring, each ZPA Module includes built-in upstream and downstream ZoneLink ports, a 9-pin connector for direct connection to a Microroller, and on-board terminals to directly wire an industry-standard 24-volt direct current (VDC) sensor with NPN output.

  • Provides built-in control logic for single zone ZPA on a powered roller conveyor.
  • Uses innovative zone-to-zone communication and connection method, saving installation time and cost.
  • Combines with ZoneLink interface modules for infeed and outfeed links to other parts of the conveyor control system.
  • Combines with a ZoneLink Controller for merges, diverts and right angle transfers on a powered roller conveyor.
