VC200RD Reverse Detection Module
The VC200RD-Reverse Rotation Monitor provides an early indication of a reverse rotation event. It is particularly useful on machines such as pumps, hydraulic turbines, and compressors that can rotate in the wrong direction during process upset conditions and thereby damage the machine.
This signal conditioner is a zero speed/standstill monitor that accepts input frequency pulses and triggers an output when the frequency drops below a selected value.
Two startup override values are available. This unit can also be used to determine rotation direction. The available diagnostic LEDs show rotation detection, limit trip indicator, power on and hardware error indication.
