Action 4382-2000-D DC Input Bipolar Output Field Isolator

AP4382-2000-D Action Pak DC Input Bipolar Output Field Isolator is a single‑channel signal conditioner designed for mounting in an Action Pak rack. It provides optical isolation between a DC input and a bipolar DC voltage output, with isolation up to 1500 VDC between input and output. The module is in an 8‑pin package and is powered from a 120 VAC supply, while handling a DC input on the signal side. It also supports bipolar inputs and offers selectable normal or reverse operating polarity, enabling flexible signal mapping. Typical applications include interfacing DC sensors or transducers to PLC or other instrumentation where isolated, bipolar outputs are required, such as eliminating ground loops and protecting control devices from field‑side transients.
