Product description
Main feature
● EDA9033G module is an intelligent three-phase electric parameter data comprehensive acquisition module.The three-meter method is used to accurately measure the three phase current, three phase voltage (true RMS), active power, reactive power, power factor, frequency, positive and negative active power, positive and negative reactive power in three-phase three-wire or three-phase four-wire AC circuits。And with 2 switching input and 2 switching output (1 can be set as the upper and lower limit alarm output of each parameter)。
● The input is three-phase voltage (0-500V), three-phase current (0-1000A);The output is a digital signal with an RS-485 or RS-232 interface，There are three communication protocols supported: (ASCII) Advantech ADAM compatible communication protocol, hexadecimal LC-04 protocol, MODBUS-RTU protocol。
Product function
● The EDA9033G module can be widely used in various industrial control and measurement systems and various distributed/distributed power monitoring systems。
● The EDA9033G module is a cost-effective intelligent electrical parameter transmitter，It can replace the past current, voltage, power, power factor, electricity and other transmitters and measure the standard output signal of these transmitters in the module，It can greatly reduce the system cost, Convenient field wiring，Improve system reliability。 Its 485 bus output and ASCII code instruction set compatible with NuDAM, ADAM and other modules, so that it can be hung on the same 485 bus with other manufacturers' control modules, and easy computer programming, so that you can easily build your own measurement and control system。
● Using electromagnetic isolation and photoelectric isolation technology, voltage input, current input and output are completely isolated。
