This bipolar signal scaling module is designed to be used as a general purpose linear, bipolar gain block or signal level converter. The module can be used for current to voltage or voltage to voltage level conversion. The three input terminals allow multiple input signals be summed and scaled into a common output. The module provides both a non-inverted and inverted voltage output signal.
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 signal scaling module includes controls to set the zero and span. The zero adjustment can be used to remove the offset from input signals that do not go to zero. The span is used to scale and set the output voltage value for a specific input signal. Three signal input connections are provided, one input is left uncommitted and may be configured by the user to accept a non-standard input signal level. The module requires a bipolar 10 to 30 volt DC power supply for operation.
The circuit board is solder masked. All external power and valve coil connections are made to a barrier type terminal block with #6-32 captive wire clamping plates. All external connections are clearly marked on the board. The board can be mounted in the user's control enclosure on standoffs or located in plastic mounting track.
Applications: General purpose signal conditioner. Use to sum and convert single ended analog input voltages or currents to a different output voltage or polarity.
