Product description
Main feature
● EDA9033A 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, active power and other electrical parameters in three-phase three-wire or three-phase four-wire AC circuits。
● Its 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，Three communication protocols are supported: ASCII, hexadecimal LC-01, and MODBUS-RTU，The three protocols can be identified and used simultaneously，No configuration required。
● The EDA9033A module can be widely used in various industrial control and measurement systems and various distributed/distributed power monitoring systems。
● EDA9033A 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。It can be hung on the same 485 bus with other manufacturers' control modules, and it is easy to program the computer, 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。
