Model TA
WHAT IS IT? The Model TA is a belt mis-alignment control that provides an indication when a conveyor belt has drifted off to a dangerous misalignment condition. The output contacts of the Model TA can control up to two separate circuits, one for machinery shutdown and one for an alarm.
WHY IS IT NECESSARY? The Model TA is relatively inexpensive protection that provides benefit by saving the time, money, and labor associated with replacing a damaged conveyor belt.
