Three-phase multi-function meter data collection
D225 equipment supports DL/T645-1997 and DL/T645-2007 protocol to Modbus protocol, and
supports up to 100 DL/T645-1997 or 100 DL/T645-2007 protocol international electric meter
devices, and only supports the meter address 000000000000-000000000099 The meter is
connected to the RS485 port of the D225 device to convert the data collected by the meter into
Modbus TCP protocol, which is convenient for docking with PLC, DCS system, SCADA system and
other upper computers, and can also be converted to Modbus RTU protocol. Data is transferred to
the cloud platform.
