The single-channel 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 1 channel of input signal detection and 1 channel of relay output, which can be used for digital detection or power control occasions. Communication protocol: support standard Modbus RTU protocol. Communication interface: Support RS232/TTL UART interface. The operation is simple and easy to understand.
1. Onboard mature and stable 8bit MCU and MAX3232 level conversion chip; 2. Communication protocol: support standard Modbus RTU protocol; 3. Communication interface: support RS232/TTL UART interface; 4. Communication baud rate: 4800/9600/19200, default 9600bps, support power-down save; 5. Optocoupler input signal range: DC3.3-24V (this input cannot be used for relay control); 6. Output signal: relay switch signal, support manual, flash-off, flash-off mode, the delay base of flash-off/flash-off is 0.1S, and the maximum flash-off/flash-off time can be set to OxFFFF*0.1S=6553.5S; 7. Device address: range 1-255, default 255, support power-down save; 8. The baud rate, input signal, relay status, and device address can be read using software/commands; 9. On-board 1-way 5V, 10A/250VAC10A/30VDC relay, which can be pulled in 100,000 times continuously, has diode bleed protection, and has a short response time; 10. On-board relay switch indicator light; 11. Supply voltage: DC7-24V Size: 79 x 49mm Material: PCB colour: blue
