In February 4B Components introduced its Watchdog Super Elite monitoring system for bucket elevators and conveyors. It has now extended the capabilities of the control unit through the introduction of NTC and PLC expansion boards.
The NTC expansion board allows up to 12 additional NTC inputs to be added for additional temperature monitoring. The PLC board is a cost effective, basic programming card providing 4 solid state relay outputs for belt speed, belt misalignment, bearing temperature and plug indication.
The Watchdog™ Super Elite (WDC4) is easy to install and simple to set-up. The system processes signals from up to 27 sensors* for belt speed, belt misalignment, continuous bearing temperature, pulley misalignment and plug conditions on bucket elevators or conveyors. When an alarm condition is detected the system will log the details, sound an alarm and provide shutdown control of the elevator/conveyor and feeding system.
The Watchdog System is Class II dust hazard area approved by CSA/NRTL for use in Canada and the USA.
