About this item

  • This relay module board's working voltage is DC 12V and standby current is11mA.Under the MODBUS command mode, this relay module can support up to 64 devices in parallel.
  • MODBUS commands can be made serial HyperTerminal (serial assistant) or "Modbus Poll" enter,and MODBUS RTU command control mode, the maximum delay is 255 seconds.
  • MODBUS command mode (HEX), you can control a variety of ways: Serial Hyper Terminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control.
  • This relay module has 6 commands: "Open", "close", "Momentary", "Self-locking", "Interlock" and "Delay".
  • We strive to provide you with the highest quality product and the best customer experience, if you're not entirely satisfied, please just feel to us at any time.

The product seems very good very well packaged. The only problem it has no documentation neither information where to download the command instructions.

Great board for the price. Used it as an introductory into the modbus world. In case anyone was wondering (as I was) how to actually utilize all of the relay modes, this is what you send in hex (decimal) to the corresponding address (register 1 being relay 1 and so on):Open - 100 (256)Close - 200 (512) Momentary/Toggle - 300 (768)Self-locking - 400 (1024) Interlock - 500 (1280) Delay - 600 (1536)When using a program like modpoll, make sure to send the command in (hex). And for some reason on modpoll, it does not like writing multiple relays at a time. If you write a program in visual studio, it has no problems though.
