2X Modbus-Rtu 8 Channel Relay Module Modbus RTU 8 Input RS485 Communication TTL Kuvaus

1. Mature and stable 8-bit MCU board: and MAX485 level conversion chip
2. Communication protocol: Supports standard Modbus RTU protocol
3. Communication interface: Supports RS485/TTL UART interface
4. Communication baud rate: 4800/9600/19200, default 9600bps, supports power-off saving
5. Optocoupler input signal range: DC3.3-30V (this input cannot be used for relay control)

Output signal: Relay signal, supporting manual, flash close, and flash break modes. The delay base for flash close/flash break is 0.1s, and the maximum set flash close/flash break is 0 XFFFF x 0.1S=65535 x 0.1s=6553.5s
Device address: Range 1-255, default 255, supports power-off saving
Board 1 circuit 5V, 10A/250V AC 10A/30V relay, capable of continuously attracting 100000 times with diode surge protection and short response
board relay indicator light
Power supply voltage: DC7-24V, with input anti reverse connection protection
