SKU:XM0007
Regular price $17.99 USD

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.
  • Product parameter
  • Onboard mature and stable STM8S103K3T6 MCU and MAX485 level conversion chip
  • Communication protocol: support standard Modbus RTU protocol
  • Communication interface: TTL UART interface supporting RS485/5V level
  • Communication baud rate: 4800/9600/19200, default 9600bps, support power-off save
  • Optocoupler input signal range: DC3.3-30V (this input cannot be used for relay control)
  • 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
  • Device address: range 1-255, default 255, support power-off save
  • Baud rate, input signal, relay status, device address can be read by software/command
  • 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
  • On-board relay switch indicator
  •  Reserve the STM8 SWIM program programming port to support customers' secondary development and download their own firmware
  • Power supply voltage: DC7-30V, using 5.08mm terminal power supply
