Short description: 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. 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.” U s 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 mA. Features: PC configuration interface Supports different Rogowski coil types Digital switching output (configurable switching thresholds) Configurable output signal Configuration via DIP switch 3-way electrical isolation with 2.5 kV test voltage No current bar interruption during installation Measurement range overflow indication
