Description
The 07KP53 module serves as an intelligent gateway for AC31 PLC, facilitating communication with various Modbus compatible devices including HMI, inverters, meters, and other PLCs. It supports both master and slave operating modes of Modbus RTU protocol.
This module has electrical isolation function, high anti-interference ability, dual independent serial channels (RS-232 and RS-485), and front panel LED indicator lights for real-time status and fault diagnosis. It supports up to 128 slaves on the RS-485 bus and configures baud rate, parity, and protocol mode through DIP switches.
Its compact DIN rail mounting design ensures easy integration into control cabinets, making it an ideal choice for industrial automation, process control, and building automation systems that require reliable Modbus connectivity.
