RS9905FN configuration speed positive and negative rotation monitoring and protection device (RS9001FN configuration speed positive and negative rotation monitoring and protection device) is a high-precision and high-reliability speed positive and negative rotation protection device (instrument), which can measure any speed positive and negative rotation in the range of 0.2Hz ~ 20KHz, and can be equipped with eddy current sensors, passive magnetoelectric sensors and active magnetoelectric sensors A surname; Commonly used to measure the rotation speed of 3 teeth reverse monitoring protection. The monitoring protection device (protection instrument) can be configured to set speed measurement range, alarm value, relay (overspeed, reverse) working mode, relay (overspeed, reverse) output logic, etc. Standard analog output (4 ~ 20mA or 1 ~ 5VDC), can be directly connected to PLC, DCS, DAS and other industrial control systems.
