8Channels DC 12V RS485 / TTL Relay Module Modbus Rtu 485 Control Switch

 
8-channel Modbus relay module
The 8-channel Modbus relay module is equipped with a mature and stable 8-bit MCU and RS485 level communication chip. Using standard MODBUS RTU format RS485 communication protocol, it can realize 8 input signal detection and 8 relay output, which can be used for digital quantity detection or power control occasions.

Parameter:
1. Onboard mature and stable STM8S103K3T6 MCU and MAX485 level conversion chip
2. Communication protocol: support standard Modbus RTU protocol
3. Communication interface: TTL UART interface supporting RS485/5V level
4. Communication baud rate: 4800/9600/19200, default 9600bps, support power-off save
5. Optocoupler input signal range: DC3.3-30V (this input cannot be used for relay control)
6. Output signal: relay switch signal, support manual, flash word, flash mode, flash off/flash
The base number of the interruption delay is 0.1S, and the maximum flash word/flash time can be set to OxFFFF*0.1S=6553.5S
7. Device address: range 1-255, default 255, support power-off save
8. Baud rate, input signal, relay status, device address can be read by software/command
9. There are 8 5V, 10A/250V AC 10A/30V DC relays onboard, which can be continuously closed for 10 times, with diode effusion protection, and short response time
10. On-board relay switch indicator
11. Reserve the STM8 SWIM program programming port to support customers' secondary development and download their own firmware
12. Power supply voltage: DC7-30V, using 5.08mm terminal power supply
