Modbus Rtu Relay Module 8 Channel RS485 TTL 7-30V Multifunction Control Switch
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.
Product 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
Package Include:
1pc x 8-channel relay module
