Overview
EDA9033A three-phase electrical parameter acquisition module
Product Details
main features
●EDA9033A module is an intelligent three-phase electrical parameter data comprehensive acquisition module; The three meter method accurately measures electrical parameters such as three-phase current, three-phase voltage (true RMS), active power, reactive power, power factor, and active energy in three-phase three wire or three-phase four wire AC circuits.
●Its input is three-phase voltage (0-500V) and three-phase current (0-1000A); Output digital signals as RS-485 or RS-232 interfaces, supporting three communication protocols: ASCII code protocol, hexadecimal LC-01 protocol, and MODBUS-RTU protocol. All three protocols can be recognized and used simultaneously without configuration.
●The EDA9033A module can be widely used in various industrial control and measurement systems, as well as various distributed/distributed power monitoring systems.
●The EDA9033A module is a cost-effective intelligent electrical parameter transmitter that can replace a series of transmitters such as current, voltage, power, power factor, and electricity in the past, as well as the analog input module that measures the standard output signals of these transmitters. It can greatly reduce system costs, facilitate on-site wiring, and improve system reliability. It can be hung on the same 485 bus with control modules from other manufacturers, and is easy to program with computers, making it easy for you to build your own measurement and control system. Adopting electromagnetic isolation and optoelectronic isolation technology, the voltage input, current input, and output are completely isolated.
