The AVI-F-series I/F conversion module is a temperature compensated high-precision current/frequency converter, which adopts a charge integration method and can continuously convert the current signals of three accelerometers simultaneously. The output of the I/F converter includes a pulse output mode, and also adds the function of timing the serial port 422 to send the accumulated number of pulses. The components used in this series of products are all 100% domestically produced, with a range of up to ±42mA.

The AVI-E-series I/F conversion module is a high-precision current/frequency converter that uses charge integration to continuously convert the current signals of three accelerometers simultaneously. The components used in this series of products are all 100% domestically produced, with a range of ±20mA and adjustable scaling factor. It has the characteristics of small zero position, low power consumption, low temperature, and autonomous controllability.
