Measuring Module DC
Measuring Module DC Voltage, with Electrical Isolation, 4kV
| • Acquisition of the momentary, maximum, minimum and average value, plus transferring data of each measuring point scan to the ALMEMO® device. |
| • DC voltage or DC current signal are scanned with 1kHz. |
| • Pure digital data transmission to the measuring instrument. |
| • Connector sockets electrically isolated and overvoltageprotected. |
