Product description

Two 10A relay controllers, with switch closed or open output, can be used for smart home control, and can be used for secondary development with mobile phones or computers to remotely control electric equipment such as lights, motors, and provide C++ source code. Reliable network connection, the router restarts after the network is disconnected, the network connection can be reliably restored, and it can be controlled remotely across the gateway. This product is powered by 5V, with two relays normally open output, without normally closed output. Support MODBUS TCP protocol, can connect with Kingview. Support 4 network connections in TCP server mode (the product that only supports one connection on the market).



Feature of product
1. Support working in TCP server, TCP client, UDP mode.
2. It supports 4 client connections under the TCP server mode.
3. Support MODBUS TCP protocol and Kingview.
4. Supports online update procedures, which is very convenient for customers to customize procedures.
5. The device name can be customized, and the Chinese definition is supported. When there are many devices, there is no need to record the complicated IP number.
6. The heartbeat packet time can be customized, and the reliability of the network is restored
7. The 32-bit microcontroller (STM32F103C8) with the high-performance Cortex-M3 core is used instead of the 8-bit microcontroller on the market. The network chip uses the hardware protocol W5500 instead of the low-cost ENC28J60.

Product description

1、Support TCP server, TCP client, UDP

2、Supporting 4 client connections in the TCP server.Assume that the local port is 5000.Port 5000,5001,5002,5003 can be connected to the TCP client.

3、Support TCP MODBUS protocol


Applications:
1. Can be used for smart home control, control router restart after disconnection, etc.
2. It can remotely control lights, motors, and other electrical equipment with mobile phones or computers for secondary development.
3. It can be used for power failure detection in the computer room, can be connected to a human infrared sensor, can be connected to a key switch, and can be connected to a smoke alarm output.
4. It can be used for access control, control the computer to turn on, and remotely control electrical appliances
5. It can be connected to the output of the smoke alarm and the output of the human body infrared device.
6. It can be connected to a key switch, any passive switch input, or an active switch input (5V active switch).
7. It can be controlled by external network, and can be remotely controlled by mobile phone (mobile APP must be developed by yourself).

Control command

1、Sent “on1”to the HHC-NET2D will turn on the First relay

2、Sent “on2”to the HHC-NET2D will turn on the Second relay

3、Sent “off1”to the HHC-NET2D will turn off the First relay

4、Sent “off2”to the HHC-NET2D will turn off the Second relay

timing control

Sent “on1:01”to the  HHC-NET2D.The First relay will be close after one second turning on.01 means a delay of 1 second.Delay range from 01 to 99 seconds.

Parameter configuration

Click search button,It is will search for devices within the local area network.

Double click the device that has been searched.The parameters that will be read to the device are shown below.

The Time Heartbeat option to detect the timing of the device to receive data.

Unit is 5 seconds.The above setup means that if you do not receive the control command over 2 minutes, the device will re initialize the network.

Restore factory settings

Dial out the hat of P5,Re power supply.It will restore factory settings.The default parameters are shown in the following diagram.
