Boards Expand Belt Monitoring System
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,
and plug indication. The Watchdog
System is Class II dust hazard
area approved by CSA/NRTL
for use in Canada and the USA.
