Instrument Follower With
Unipolar Voltage Input

This instrument follower module is designed to be used as a general purpose linear, signal level conditioner. The module will convert a voltage input signal at one level into a voltage output signal at another level. This device should be used in unidirectional applications where the controller command signal generator voltage must be converted before it is applied to the controller. A typical application uses this module to condition the signal from a tachometer that is used as the command input to follower drive.

This industrial grade module includes a stable DC coupled amplifier and will maintain the output signal within 1% of it's setting as the input power supply voltage and ambient temperature are varied over the specified range. The module is designed for use in unipolar applications only, the input and output signals must be positive voltages. Each instrument follower module includes control to set the maximum signal output. This span adjustment is used to scale and set the output voltage to a specific value when the input signal is at it's maximum. In operation, as the input voltage varies from zero to maximum the output voltage signal will vary from zero to the value set with the span adjustment. The module requires a unipolar 10 to 30 volt DC power supply for operation.

The instrument follower module is designed to be mounted in the user's panel on standoffs or in plastic mounting track with additional devices. The circuit board is solder masked. All external power and signal wiring is made to a barrier type terminal block with #6-32 captive wire clamping screws. All external connections and controls are clearly marked on the board.

Applications: General purpose unipolar voltage level shifting, normally used to convert a high voltage source to a lower voltage for indication or control devices
