ISD201SM is an isolated, rated Pulse Position Modulation (PPM) digital isolated amplifier module developed by Isocom Components. The module is an all-in-one design, with built-in isolation, signal conditioning, and digital interface capabilities. It features an isolated digital-to-analog converter, coupled with an isolated amplifier stage and programmable gain. This makes it ideal for use in distributed control systems, data acquisition, and other applications requiring high-accuracy signal isolation. The module can be programmed for either single-ended or differential input, with independently selectable gains for each input for maximum flexibility. The device also includes a temperature-compensated voltage reference for precision measurement and provides over-voltage and reverse-polarity protection for added safety.
