The Isolated Current-Current Converter accepts a 24VDC power supply (nominal). A bipolar 0-200 mA input signal is converted to a 4-20 mA current output. Span and zero is user adjustable. Diagnostic LEDs indicate power and operational status. The output LED is on when the load, input signal and power supply are connected. The LED flashes when the load is disconnected. The load can be floating or grounded. The unit is potted (prototype is conformal coated) and available in a DIN rail mount housing.
