Boards Expand Belt Monitoring System Capability

4B Components Ltd. unveiled the NTC and PLC expansion boards, accessories that extend the capability of its Watchdog Super Elite monitoring system for bucket elevators and conveyors. The Watchdog Super Elite (WDC4), with a 3.5-in. color graphics LCD display, processes signals from 15 sensor inputs. It monitors belt alignment, speed and slip; continuous bearing temperature; pulley alignment; and plug conditions. When an aberrant condition is detected, the system will log the details, sound an alarm, and provide shutdown control of the elevator or conveyor and feeding system. The NTC expansion board allows up to 12 additional NTC inputs. The PLC programming card provides four solid state relay outputs for belt speed, belt misalignment, bearing temperature and plug indication. The Watchdog System is Class II dust hazard area approved by CSA/NRTL for use in Canada and the USA.
