  • Page 4: Application

    Transformation ratios can be entered to the instrument, which means that all primary measurement data can be displayed directly at the A2000. Maximum values are stored to memory for every measured or cal- culated quantity. If limit values are exceeded, corrective action can be triggered via relay outputs. Energy meters, recorders, data loggers and control loops can be connected to the digital and analog outputs.

  • Page 5: Inputs, Outputs And Interfaces

    Inputs, Outputs and Interfaces Current Inputs All current inputs are isolated from one another. If measurements are performed with external trans- formers, their primary and secondary current values must be entered, in order to enable direct display of current values. Switching between the two meas. ranges (1 A and 5 A) is accomplished via software. Connection with 3 current transformers Connection with 2 current transformers in 3/4-wire systems (4L)
