This current to voltage converter module is designed to be used as a general purpose linear, signal level conditioner. The module will convert a 4 to 20 ma. signal into a voltage. This device should be used in unidirectional applications where the output voltage will vary from zero to maximum as the input changes from 4 to 20 ma.
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.
Each current to voltage converter module includes controls to set the zero and span. The zero adjustment is used to remove the offset from the 4 ma. input signal and produce a zero output voltage. The span is used to scale and set the output voltage to a specific value when the input signal is at 20 ma. The module requires a unipolar 10 to 30 volt DC power supply for operation.
The current to voltage converter 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: Convert 4 to 20 ma. output signal from transducers and process control devices to a voltage source.
