DKM-430-PRO Multi Circuits Energy Meter RS485 is a precision instrument allowing the measurement, recording, and remote monitoring of 10 3-phased or 30 single-phased feeders (or any combination of these two) in AC distribution panels.
The unit offers additional 24 inputs capable of being used as FUSE detectors or digital inputs. Several combinations of these two are available. The optional internal GPRS modem allows remote monitoring and control of the distribution panel without the use of any additional module. The standard model of the Ac Multi Channel Power Meter has a universal 85-300VAC supply. 24-110VDC supply versions are available.
The isolated RS-485 MODBUS RTU data port is unaffected by ground potential differences and allows the safe transmission of information to monitoring and automation systems.
