API 4300 G & 4310 G Series DC to DC Transmitters

The API 4300 G and API 4310 G are factory configured to accept a DC voltage or current input and provide an optically isolated DC voltage or current output that is linearly related to the input.

The API 4310 G utilizes an ultra-stable input amplifier for reliable operation with input signals as low as 10 mVDC. Typical applications include signal isolation, conversion, boosting or a combination of the three. Full 3-way isolation (input, output, power) makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.

When a milliamp input is specified, a loop excitation power supply is included that may be wired for sinking or sourcing to allow you to use a powered or passive input device. When a milliamp output is ordered, it provides power to the output current loop (sourcing). If an unpowered (sinking) current output is required, order the EXTSUP option for an open collector output. Common ranges as well as custom ranges are possible. Consult the factory for assistance with special ranges.
