Digital Data Logger RPM-16-4-3

Digital Data Logger RPM-16-4-3

Product Details:

Model RPM-416
Usage Industrial, Laboratory

RPM-16-4-3 digital electric process recorder is used for:

  • Measuring the actual alternating voltage value
  • Measuring the actual alternating current value
  • Measuring the temperature
  • Receiving data from primary transformers with a standard current or voltage input
  • Storing the measured values in an external medium, such as USB-FLASH
  • The register is a 16-channel data collection system that allows data archiving in an external medium
  • The unit has plastic housing and is installed on a standard DIN-rail

The operating principle of the register is based on reading the values from all sensors, accumulating the data in its internal memory and writing it to an external medium via an integrated USB-port. A text editor or Reg_RPM software can be used to view the data as diagrams.

Channel Distribution:

  • Voltage measurement – 4 channels
  • Current measurement – 3 channels
  • Temperature measurement – 2 channels
  • Differential input for DC voltage measurement (0 - 10V) – 1 channel
  • Standard input for DC current meaasurement (0 - 20mA) – 1 channel
  • Standard input for digital signal (binary) – 5 channels

Additional Information:

  • Item Code: RPM-16-4-3
