The DC to DC isolation transmitter models RD1～RD3 can input various DC voltage or current signals and can also output desired voltage or current signals isolated from the input. These transmitters are available in the standard wall-mount case, or in a special plug-in rack mount case. (See model PD1, Case C.)
