Three new microprocessor-based controllers for motor-driven roller conveyor systems are available from Holjeron, the electronic controls subsidiary of Matthews International. They include a stand-alone UBT controller, a serial interface and the Microroller.
Holjeron's new UBT controller, the latest in its ZoneLink family of products, can easily be configured for either merge, divert or transfer mode through a serial port and is simply plugged into the line where needed with no additional programming required. This controller can be used in place of traditional PLCs, which require a significant investment in programming. For higher-level supervisory control, the UBT controller is available in a version that interfaces directly with a DeviceNet network.
The new ZL.S-F32 ZoneLink Serial Interface Card makes it convenient to implement .S technology by permitting communication through a serial port on a PC or PLC. Holjeron's ZoneLink.S technology allows distributed microprocessor-based controllers to communicate with one another, enabling users to configure and monitor a Zero Pressure Accumulation conveyor line easily and inexpensively. .S technology also provides predictive diagnostics and remote speed control.
The third new Holjeron microprocessorbased controller is a low-cost driver. The ZL- DK100 Microroller driver is capable of setting and maintaining the speeds of adjacent conveyor zones to within ±1 RPM of each other—even under load—with just the flick of a switch. Normally, matching speeds is labor-intensive and, therefore, expensive, as well as relatively imprecise. Now the Microroller driver assures that zone-to-zone speed will be identical to within a couple of inches per minute. This closed-loop speed control has always been a feature of Holjeron's higher-end controllers; but with the ZL-DK100, it is available for the same price as competing non-microprocessorbased control systems.
