DKM-250 DC ENERGY ANALYZER AND EARTH LEAKAGE DETECTOR

The DKM-250 is a precision instrument designed for measuring, displaying and remote monitoring earth leakage and various DC parameters in a DC distribution box.
The unit features a 32-bit ARM core microcontroller.
The unit is supplied from the measuring DC voltage input. Operating range is between 19 and 150VDC.
The current input of the unit is isolated from the rest of the circuit and has different circuit options:
● External current shunt (standard)
● Internal current shunt
● Hall Effect sensor input
● 4-20mA analog input

The unit has 2 digital inputs and 2 relay outputs, both of them programmable for required functions.
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. Program parameters may be uploaded to the unit through the RS485 port.
The unit may output any measured value as analog signal through its 4-20mA port. This
output allows easy connection to PLC systems.

FEATURES:
● Displays earth leakage in %
● Various current input options
● 2 programmable relay outputs
● 2 programmable digital inputs
● Programmable 4-20mA analog output
● Demand, Min & Max records
● Fully isolated RS-485 serial port
● MODBUS-RTU communications
● Bidirectional current & power measurement
● Bidirectional kW-h energy counter
● Bidirectional A-h counter
● Hours run counter
● Front panel programming
● Wide operating temperature range
● Sealed front panel (IP65 with gasket)
● Two part connection system
