8 Channel Programmable RS485 Serial Port Relay Board Smart Home Lighting Control Module Modbus Switch Input and Output

Product description

This product is an intelligent programmable controller that does not require a gateway. The output uses 8 imported Omron 16A high-power relays, 8 optically isolated inputs, standard 485 and network cards. It is a smaller size among similar products on the market at present, accounting for only 4 open positions, the same layer of guide rails are free of wire splicing, and a variety of networking methods are suitable for smart homes, commercial lighting, smart agriculture and other automated fields.

1. The ultra-small volume only occupies 4 open positions, which is a powerful tool for small electric boxes in smart homes.

2. Humanized design, the same layer of guide rails can realize wire-free splicing expansion

3. Free programming through the host computer software, all internal resources are open

4. Use a variety of communication methods to make the module more compatible.

5. Cooperate with the voice module.

6. Support API control to facilitate connection with third-party platforms.

7. Support protocol conversion, protocol transparent transmission, wireless to 485, network to 485, etc.

8. The built-in high-precision clock chip can realize local timing control

9. Built-in wireless receiving module, which can be controlled by remote control and free sticker switch

10. Adopt the code switch address setting, which is convenient and quick.

11. Built-in clock chip can realize local timing control.

12. Support 99% of 485 switches on the market, dry contact switches, and sensor linkage

Support multiple communication modes

Support 485 protocol, MODBUS protocol, TCP/IP protocol, UDP protocol, MQTT protocol and other communication interfaces RS485 bus, RJ45 network cable, WIFI, GPRS, 315M, 433M

Device ID

Address setting

There is a 4-position side switch on this module. The factory address defaults to 0, and the address can be set to 0-15.

Note: The newly set ID address will take effect after the device is powered off and restarted

Control instruction

[Baud rate] 9600 [Check digit] N [Data bit] 8 [Stop bit] 1

All hexadecimal commands

Among them, "ID" represents the set ID address, and 0x00 is the broadcast code
