Product Description

HHC-N2DC Ethernet 2 Channel Relay Board Delay Switch Smart Home Controller Module TCP UDP Connection

Specifications:

 

Features:

  1. This product is resistant to high temperature and can work at -40℃ to + 85℃.

  2. Strong anti-interference ability, can be connected to the external large current ac contactor and relay, in the strong electromagnetic interference will not crash.

  3. The real 100M speed, in the case of zero delay command can be reliable communication.

  4. Support for automatic IP acquisition.

  5. Support 10 TCP client connections under the TCP server.

  6. Through the configuration software, you can configure 5 working methods: TCP server, TCP client, UDP server, UDP client, DNS domain name.


Specification:
Material: Plastic 
Weight: 190g/6.7oz
DC Power Supply: 7-24V
Industrial grade working environment: -40℃ ~ +8℃
Relay output, no voltage or current output. Maximum load, DC 5A, AC 10A, maximum voltage 250V.
COM1 first relay common terminal, NO1 first relay normally open, NC1 second relay normally closed terminal. COM2, NO2, NC2 are the second way, the function is the same as above.
Reset, used to restore the factory equipment. In the case of no power on, stick a toothpick or a point through the reset hole and connect it to the power supply. After the LED light is on, release the toothpick and restore the IP of the factory equipment to 192.168.0.105. If you want to upgrade software, be sure to upgrade in the reset state. After the reset is successful, the LED light flashes (twice per second). If you want the controller to work normally, you need to power it again. The LED is in a slow flash state (flash every second).

Working Mode: 
Work mode is configured with the provided configuration software.
1. TCP server
In this mode, devices can only be connected through TCP clients, supporting 10 TCP client connections.
2. TCP client
In this mode, the device actively connects to the TCP server (remote IP and remote port number are parameters of the device connection). Only one server can be connected.
3. UDP server
In this mode, any UDP communication is supported.
4. UDP client
In this mode, only UDP communications that match the remote IP and remote port number (configuration software Settings) are supported.
5. DNS domain name
In this mode, the device connects to the TCP server (which is the remote port) of the bound domain name as a TCP client.

Order description:
Commands are sent and received in character form.
Open the first relay:  send  on1;  return  on1
Open the second relay: send on2;  return  on2
Off the first relay: send  off1;   return  off1
Close the second circuit relay: send  off2;  return  off2
Read the state of the first relay: send  read1; return  on1, (indicates that the relay is open, and if return: off1 indicates that the relay is closed)
Read the state of the relay in the second circuit: send  read2;  return  on2 (indicates that the relay is open, and if return: off2 indicates that the relay is closed)

High-speed communication:
High-speed communication, the computer to send data to the device no longer have to wait, just send the device can be processed. Working under the TCP server, the device supports 10 TCP clients to send data continuously. SPI port is not comparable to the network chip such as ENC28J60, W5500 comparable chip, the real 100M network port.
Industrial working environment:
Working conditions -40 to +80 degrees. Not afraid of cold and heat. The inductive load will not break the network. For example, the external 220V AC contact changer will still work stably in the network.
