API 4380 G Series DC to DC Transmitters

The API 4380 G accepts a DC voltage or current input and provides an optically isolated DC voltage or current output that is linearly related to the input. Typical applications include signal isolation, signal conversion, signal boosting or a combination of the three.

The optical isolation between input and output makes this module useful for ground loop elimination, common mode signal rejection, and noise pickup reduction. The module power supply is isolated, resulting in full 3-way (input, output, power) isolation.

The API 4380 G input and output can be field-configured via external rotary and slide switches. Common range settings are on the module label. Most common ranges are built-in, and can be selected from the table on the module, however virtually unlimited combinations are possible. Consult the factory for assistance with special ranges. The built-in 18 VDC unregulated loop excitation power supply can be used to power passive input devices.
