LC 1 channel Modbus relay module equipped with mature and stable 8-bit MCU and RS485 level communication chip,adopt standard MODBUS RTU format RS485 communication protocol, It can realize 1-way input signal detection and 1-way relay output, can be used for digital detection or power control occasions.

Features:

1. On-board mature and stable 8bit MCU and MAX485 level conversion chip

2. Communication protocol: support standard Modbus RTU protocol

3. Communication interface: Support RS485 / TTL UART interface

4. Communication baud rate: 4800/9600/19200, default 9600bps, support power saving

5. Photocoupler input signal range: DC3.3-30V (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, the maximum settable flash-off / flash-off time is 0xFFFF * 0.1S = 65535 * 0.1 S = 6553.5S

7. Device address: range 1-255, default 255, support power-down save
