RS9905N Configuration speed monitoring and protection device (RS9001N configuration speed monitoring and protection device) is a high precision, high reliability speed positive and negative rotation protection device (instrument), can measure any speed in the range of 0.2Hz ~ 20KHz, can be equipped with eddy current sensor, passive magnetoelectric sensor, active magnetoelectric sensor. 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.
