4. Can be used for access control, computer control, remote control of electrical appliances
5. Can be connected to smoke alarm output, can be connected to human body infrared output
6. It can be connected to a key switch, can be connected to any passive switching input, can also be connected to an active switching input (connected to a 5V active switching).
7. It can be controlled by an external network and can be controlled remotely by a mobile phone.
Control Instruction:
Send: on1 turns on the first relay
Send: off1 turns off the first relay; the second control method is the same.
Send: read1 means reading the status of the first relay. If it returns on1, it means that the first relay is on and off1 means that the first relay is off.
Delay control, such as
Send: on1:02 means the relay will open after 2 seconds and send: 12 means the relay will open after 12 seconds. The maximum delay is 99 seconds.
For MODBUS TCP
1.01 operation code
This code is for reading the status of the relay. The relay address is
