Voltage to Current

This voltage to current converter board provides 4 current sources, controlled through analog input voltage.The current sources draw current from a common VBAT power supply input, currents are expected to return to VBAT Ground connection.

All inputs are differential to avoid common ground issues, however an electrical path exist between the inputs and VBAT power supply. For proper operation, the common voltage mode applied to each input should not exceed 2 Volts. A 24 Volts auxiliary supply is required for internal circuits. This auxiliary supply input is insulated from inputs and VBAT power supply.
