C2468 Frequency to Voltage Converter, Unipolar
Description:
This frequency to voltage module is designed to convert a continuous series of digital pulses into an analog voltage. The input is designed to accept low level pulses from magnetic pickups or high level square wave signals from a shaft encoder. The output voltage is positive with a magnitude proportional to the input signal. This device may be used to provide a unidirectional analog velocity signal that is directly proportional to the output from an encoder connected to a rotating shaft.
This industrial grade module includes a transducer power supply that can be used to operate the input signal transducer. A stable reference that maintains the output signal linearity and drift too less than 1% as the input power supply voltage and ambient temperature are varied over the specified range. The digital input signal is optically isolated from the analog output. When used with multiple power supplies, the isolation feature allows operation with different common reference potentials for the input and output signals.
Each frequency to voltage converter module includes controls to set the output signal zero and span. Jumpers are supplied on the board to select the input signal source type as well as the maximum operating frequency. With the maximum operating frequency set to the low range, the rated output signal will be obtained with input signals of approximately .67 times the high range rated value. The module requires a positive 10 to 30 volt DC power supply for operation.
The circuit board is solder masked. All external connections are made to a barrier type terminal block with #6-32 captive wire clamping screws. All external connections and controls are clearly marked. The board can be mounted in the user's control enclosure on standoffs or located in plastic mounting track.
Applications:
Used to convert incremental shaft encoder or pulse pickup outputs to an analog voltage signal that can be used to provide velocity information to the user's control circuit.
