The XDB1003-3 series relay module from XIDIBEI SENSOR & CONTROL offers a versatile solution for relay control in industrial environments. It features two-way relay control and supports multiple input modes, including non-locking, self-locking, and interlocking linkage modes. With support for RS485 or RS232 communication interfaces and a configurable baud rate, the module is highly adaptable. It offers reliable performance with a wide voltage range (DC7-30V), optocoupler inputs, and relay outputs, making it ideal for various automation tasks. This module is designed for durability, with a rated voltage of up to 250VAC and a temperature range from -40℃ to 85℃.

RS485 cascade wiring method
The computer’s built-in serial port is usually RS232, which requires a 232-485 converter (active and isolated converters are recommended for industrial environments). After conversion, RS485 is divided into two wires, A and B. A is connected to the A terminal on the board, and B is connected to the B terminal on the board. The 485 shield can be connected to GND. If there are many devices, it is recommended to use twisted shielded cables and a chain network structure.
