Specifications
Digital Panel Meterprogrammable,DC4-20mA output,capacity output.
High accuracy.
Modbus -RTU protocol
YD9000 Series AC Voltage/Current Digital Panel Meter measures and displays the voltage/current of the three phase system with added functions of RS485 communication output, analog output, and contact output. It is programmable for the analog output and the contact output (Models in dimension 48mm×48mm have display function only).The digital panel meter displays real time value of voltage/current. Parameters such as address, baud rate, transformation ratio, analog output, relay output and return difference can be set manually on keyboard or by PC through RS485 communication (These parameters can not be set by the models in dimension 48mm×48mm, but can be made in the factory according to the customers requirements).With its reliable performance, YD9000 series panel meter is an economical and practical AC voltage/current measurement device.
Function Code
Models in 48 mm×48 mm×100mm has the functions of measuring and displaying only.
