In typical applications a process is monitored by a transducer, PLC, PC or some other device that provides a 0-10 Vdc or 4-20 mA signal. This signal is converted to a frequency and can be used to provide the lead signal to a closed loop controller such as our MicroSpeed 196 or as the input to an electronic counter, tachometer, etc. A regulated 10 Vdc signal is provided on the terminal strip for an input to the module if required. Zero and span potentiometers are provided to calibrate the output frequency to your requirements.

AIFO-200 Calibration Procedure Note A: The AIFO is factory calibrated for 0-10 Vdc Input and 0-2500 Hz Output. Note B: 0 Vdc Input can be obtained by connecting TB1-4 Common to TB1-5 High. A frequency measuring device must be used to calibrate the AIFO-200. Connect the measuring device to Terminal TB1-9 (Common) and TB1-7 (Frequency Output). Determine if your application requires a pull-up resistor for the frequency output. If not required, remove resistor R20 labeled “PULL-UP” on the circuit board. Turn all potentiometers fully counterclockwise. Now turn R16 zero potentiometer 11 turns clockwise....
