Holjeron: ZoneLink3 zero-pressure accumulation (ZPA) controllers

The third generation of ZoneLink3 zero-pressure accumulation (ZPA) controllers by Holjeron supports the supplier’s line of 22-watt and 35-watt Microroller, internally powered, motor-driven conveyor rollers.

The controllers are constructed with a snap-in mounting plate for tool-less connection. Equipped with on-board, pre-programmed ZPA logic, the controllers can operate in slave, manual or train modes. The devices include RJ-11 auto-sensing ports for easy integration with either NPN or PNP industrial sensors.

Features include six auxiliary inputs/output default functions (two inputs and four outputs) for enhanced diagnostics and control access. To optimize system throughput, acceleration, deceleration, speed and current limits are adjustable.

Key features include:

• 6 PNP Auxiliary I/O points provide enhanced diagnostic and control functions.
• Programmed with built-in ZPA logic including Slave, Manual, and Train Modes.
• RJ-11 auto-sensing sensor ports allows easy installation of NPN or PNP sensors.
• Speed adjustment is easy, thanks to a rotary speed selector.
• A configurable “Seek Mode” at power up will determine if a load is in the zone, but not blocking the sensor.
• Snap-in mounting plate for easy tool-less installation.
• Fully compatible with all ZoneLink Microroller Systems.
