Description

This Modbus RTU 16-Channel Relay Module features an RS485 interface and incorporates multiple isolation protection circuits. It operates at a voltage of 5V and supports communication via the RS485 interface. The module offers selectable baud rates, including 4800, 9600, 19200, 38400, 57600, 115200, 128000, and 256000. The default communication format is set to 9600-N-8-1. With 16 relay channels, each channel has a contact form of 1NO 1NC. The communication protocol adheres to the standard Modbus RTU protocol. The module can be assigned an RS485 address ranging from 1 to 255. LED indicators include STA, which is the MCU indicator flashing during normal MCU operation; TXD, the TX indicator that lights up during data transmission; and RXD, the RX indicator that lights up when data is received.
