This series of instruments employs AC sampling technology to independently measure circuit parameters such as current, voltage, and frequency, with scaling factors configurable via panel switches. They feature an RS-485 communication interface supporting the Modbus-RTU protocol; additionally, they can convert electrical signals into standard DC analog signals for transmission output, or incorporate functions such as dual-channel relay alarm outputs.
