<p><b>Short description:</b></p><p>This Rogowski signal conditioner records RMS values from alternating currents via Rogowski coil, converting the input signal into an standard analog signal on the output side.</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 mA.</p><p> </p><p><b>Features:</b></p><ul><li>PC configuration interface</li><li>Supports different Rogowski coil types</li><li>Digital switching output (configurable switching thresholds)</li><li>Configurable output signal</li><li>Configuration via DIP switch</li><li>3-way electrical isolation with 2.5 kV test voltage</li><li>No current bar interruption during installation</li><li>Measurement range overflow indication</li></ul>
