Holjeron no longer offers this product.
ZoneLink® is Holjeron’s method for linking adjacent zones in a conveyor system. This is accomplished using two electrical lines between each powered roller controller: one to signal the neighboring upstream zone it is “ready” to receive a unit, and one to let the downstream zone know it is “sending” a unit.
The ZoneLink Powered Roller Controller (PRC)—in addition to upstream and downstream ZoneLink ports—directly drives a Holjeron or Sparks Microroller and has input terminals for a sensor. Zero pressure accumulation (ZPA) logic is executed in the ZoneLink PRC.
