Used for monitoring bucket elevators and conveyors, the 4B Components Watchdog Super Elite WDC4 control unit processes signals from up to 15 sensors for belt speed, belt misalignment, continuous bearing temperature, pulley misalignment and plug conditions. When an alarm condition is detected, the unit logs the details, sounds an alarm and provides shutdown control of the elevator/conveyor and feeding system. The unit also supports belt speed monitoring for variable frequency drives and belt misalignment inputs for contact, pulse and temperature (brass rub block) sensors.
