ABSOLUTE API4380-GDC input signal regulator
The API 4380 G accepts a DC voltage or current input and provides an optically isolated DC voltage or current output that is linear to the input. Typical applications include signal isolation, signal conversion, signal enhancement, or a combination thereof.
The optical isolation between input and output allows this to be used to eliminate grounding loops in modules, common mode signal suppression and noise pickup reduction. The module power supply is separated to form a full 3-way (input, output, power) isolation. API 4380 G Inputs and outputs External rotary and slide switches can be configured in the field in the following ways.
Common range Settings are found on the module label. The most common ranges are built-in and can be selected from a table on the module, but virtually unlimited combinations are possible. Consult the factory for specific areas of assistance. The built-in 18 VDC unregulated loop excitation power supply can be used to power passive input devices.
