<p><b>Short description:</b></p><p>This configurable signal conditioner converts, amplifies, filters and electrically isolates standard analog signals.</p><p><b>Digital switching output (DO):</b></p><p>The digital switching output (DO) allows signaling of a message. Two switching behaviors can be selected for the edge:</p><p>GND switching: For all values below the lower threshold or above the upper threshold, the digital output switches to “GND.”</p><p>U<sub>s</sub> switching: For all values below the lower threshold or above the upper threshold, the digital output (DO) matches the supply voltage level.</p><p> </p><p>The preset switching thresholds are 0% and 100% of the input measurement range. These thresholds can be adjusted via the PC configuration interface. The switching threshold hysteresis is 5 mV/5 µA.</p><p> </p><p><b>Features:</b></p><ul><li>PC configuration interface</li><li>Calibrated measurement range switching</li><li>Analog unipolar and bipolar standard signals at the input</li><li>Clipping capability<br/>for analog signal limitation to output end values</li><li>3-way electrical isolation with 2.5 kV test voltage</li></ul>
