AF2131 speed monitoring module

AF2131 Speed Monitoring Module Revolution Watch   Features ● Real-time monitoring of the rotation of the motor or shaft ● Standard 35mm rail slot ● Parameter protection function ● Easy installation ● Watchdog function ● Compatible with a variety of electromagnetic eddy current speed sensors Product Introduction AF2131 speed monitoring module is suitable for speed measurement and overspeed protection of high-speed shaft, low-speed shaft and pitch system of wind turbine. By monitoring the pulses sent back by the speed sensor, when the frequency exceeds the frequency set by the panel, the dry contact of AF2131 will act to give an alarm signal, thereby realizing overspeed protection of the wind turbine. The rotation frequency range that AF2131 can measure is 0-99.9Hz. The alarm frequency point, average number of pulses and alarm hysteresis percentage can be directly set through the knob switch. The operation is intuitive and fast, and there is no need to use a computer to connect to the configuration software for setting. AF2131 has a parameter setting protection function. When the parameter setting on the panel is changed, if the user does not confirm, even if it is reset or powered off, AF2131 will not apply the setting and send a parameter modification signal.
