Measuring transformer of direct and alternating currents, converting the signal value to a normalized analog voltage signal of 0...10 V. The characteristics of these transmitters ensure high accuracy of temperature reading due to the 12-bit precision A/D converter. The device is similar in function and appearance to standard active measuring transformers, but is capable of measuring TRMS DC and AC current components. The direction of current flow can only be measured for DC currents.
This version allows user configurable span and zero ranges as well as the ModBus communication address. Basic setup can be done with a DIP switch, detailed setup can be done with a library in the Pixsys HMI development tools.
