Description
Short description:This configurable signal conditioner converts, amplifies, filters and electrically isolates standard analog signals.Digital switching output (DO):The digital switching output (DO) allows signaling of a message. Two switching behaviors can be selected for the edge:GND switching: For all values below the lower threshold or above the upper threshold, the digital output switches to “GND.”Us switching: For all values below the lower threshold or above the upper threshold, the digital output (DO) matches the supply voltage level. 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. Features:PC configuration interfaceCalibrated measurement range switchingAnalog unipolar and bipolar standard signals at the inputClipping capabilityfor analog signal limitation to output end values3-way electrical isolation with 2.5 kV test voltage
