915 Generation DC 7-24V Power Supply 4 Channel Modbus RTU Relay Module

Detailed Information About The Product:

The 4-way Modbus relay module is equipped with a mature and stable 8-bit MCU and RS232 level communication chip.
Using the standard MODBUS RTU format RS232 communication protocol, it can realize 4-channel input signal detection and 4-channel relay output, which can be used for digital quantity detection or power control occasions.
Communication protocol: support standard Modbus RTU protocol.
Communication interface: Support RS232/TTL UART interface.
Communication baud rate: 4800/9600/19200, default 9600bps, support power-down save.
