API Module Power Options

• DC Voltage Input: 0-10 mV to 0-130 V
• DC Bipolar Voltage Input: +/- 5 mV to +/- 65 V
• DC Current Input 0-200 uA to 50 mA
• DC Output: 0-1 V, 0-5 V, 0-10 V, +/- 5 V, +/- 10 V, 4-20 mA, etc.
• Field-Configurable by User

The APD 4380 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, 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.
