application:
1. Can be used for smart home control, controlling router restart after disconnection, etc.
2. Mobile phones or computers can be used to remotely control electrical equipment such as lights and motors.
3. It can be used for power outage detection in computer rooms, and can be connected to human body infrared sensors, key switches, and smoke alarm outputs.
4. Can be used for access control, computer control, and electrical remote control
5. Can be connected to smoke alarm output and human body infrared output
6. It can be connected to a key switch, any passive switch input, or an active switch input (5V active switch input).
7. It can be controlled by external network or remotely controlled by mobile phone.
Control instruction:
Send: on1 turns on the first relay
Send: off1 to turn off the first relay; the second control method is the same.
Send: read1 means reading the status of the first relay. If on1 is returned, it means the first relay is on, off1 means the first relay is off.
Delay control, e.g.
Send: on1:02 to indicate that the relay will open in 2 seconds, and send on:12 to indicate that the relay will open in 12 seconds. The maximum delay is 99 seconds.
For MODBUS TCP
1.01 opcode
This opcode reads the status of the relay. The relay address for the first channel is 0010 and the relay address for the second channel is 0011.
2.05 opcode
This opcode controls a single relay. The relay address for the first channel is 0010 and the relay address for the second channel is 0011.
3. 0F opcode
This operation code controls two relays. The relay addresses are: No.0010, No.0011.

Package Included:
1 x IP network relay module (with housing）
