Model GS-AF1B1-GxEC is a digital AC Frequency transducer with input 100Hz~10KHz(0.5A~30A) and output with RS485,supportive of Modbus RTU protocol . the input frequency signal can be a sine wave, square wave and zero-crossover wave.This model of frequency transducer is double isolated, which means both the input and output are isolated from the power supply.
The frequency transducer can be applied for power quality monitoring,generator-monitoring,muti-frequency control and monitoring and interter drives and systems etc.
