Description
Short description:This current signal conditioner measures both 0–1 A and 0–5 A AC/DC currents, converting the input signal to an standard analog signal at the output.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 mA. Features:PC configuration interfaceTrue RMS measurement or arithmetic mean valueDigital switching output (configurable switching thresholds)Switchable filter functionCalibrated measurement range switching3-way electrical isolation with 2.5 kV test voltageExtremely fast response timesMeasurement range overflow indication

Notes
| Safety Information | Input and output must be safely isolated from any hazardous live parts! |
|---|---|
| Note | Additional setting options via the WAGO Interface Configuration Software, Use shielded signal cables!Only use shielded signal cables for analog output signals.This ensures the device maintains its specified accuracy and immunity to interference, even when external disturbances affect the signal cable. |
