Appearance size: length 115 × width 90 × height 40 (mm)
Shell material: top cover ABS, bottom shell ABS, snap POM
Device address: 1~247, the default is 1, 0xfa is a general address
Installation method: rail installation
Communication Description:
Due to precision and data requirements, the registers here use floating-point types. (Floating-point data is 32 bits, which takes up four bytes altogether)
According to the ModBus-RTU protocol, each terminal has an address, which is modified by the 06 function code of modbus-RTU. The default address is 1, and the modified address range is 1~247, where 0xfa is the general query address (read unknown address data), modify unknown address data, bear in mind that this address can only be used in a single operation, forbid online reading data and modifying address).
Package List:
-1 x Current Detection Module
-10 x Transformer
Note: The RS485 communication line must not be connected to VCC and GND. Although RS485 can shield the instantaneous high voltage electromotive force, if the A+ and B- sections of RS485 are misconnected to VCC and GND, the 485 chip will be burned! Please connect first, and then check the connection is correct, and then power the module.
