BCD/mA Converter

BCD/mA Converter The BCD/mA Converter is a device designed for converting BCD (8421) signals from a diode matrix into a DC current signal.

Typically, the BCD signal used in this application features positive voltage values. For instance, the high and low levels may be +24V and 0V, respectively. An electronic circuit reads the binary BCD levels and generates a current output proportional to the decimal input, for instance 4-20 mA.

The current generating circuit also isolates the output from the BCD inputs and from the power supply inputs, preventing transients from being transmitted through the BCD/mA converter. This awards great robustness to this product and to the system which will process the current signal.
