   • SCOPEMETER                      • 3 x 4-20mA ANALOG OUTPUTS

   • 4 DIGITAL INPUTS                • 2 RELAY OUTPUTS

The DKM-409 is a precision instrument designed for displaying, logging and remote monitoring of various AC parameters in a 3-phase network.

The power supply of the unit is isolated. The supply range is 85-270V-AC and 88-400V-DC allowing universal use in AC and DC systems.


The unit has 3 x 4-20mA analog outputs. Any measurement can be output as analog value.

The unit has 4 digital inputs and 2 relay outputs with programmable functionality, selected from a list.

Thanks to its isolated RS-485 Modbus RTU comport, the device is free from ground potential difference issues and data are safely transferred to automation and monitoring systems.

The device has 1MB (optional 16MB) internal memory for the record of all electrical parameters with required frequency. Records are read through Modbus.

The graphic screen allows display of waveforms and harmonic analysis graphs.

The user configurable screen where any measured parameter set can be displayed, transforms the unit to a custom designed measurement panel.
