*
8 relays, 8 switch inputs, with full-open and full-close inputs. With power-down save function (save relay status).
Electrical parameters:
1. The power supply is DC 7-24 volts, and the DC socket or terminal block can be selected for input power. The DC connector specification is 5.5-2.1MM (outer diameter-inner diameter).
2. The board operating temperature range is -40 to 85°C
3. 8 independent relay outputs, output without voltage. The DC rating of a single relay is 10A, the AC current rating is 10A, the maximum AC rating is 250V, and the maximum DC rating is 30V.
4. 10-channel independent input.
IN9 means fully open. After IN9 has a switch input, all relays are closed. IN10 means fully closed. When IN10 has an output, all relays are closed.
The 8 inputs of IN1-IN8 can be configured into three different working modes through the configuration parameter tool, which can be selected in the "input mode" of the configuration tool.
"Normal input" mode collects input signals normally. To obtain the input status, it is necessary to send a read input status command to the device.
"Trigger relay" mode. After this mode has input, the corresponding relay state is reversed, and IN1-IN8 control corresponds to 1-8 relays.
"Active upload" mode, this mode will actively send the input status to the network connected to the device when the input changes.
5. The device has an RS485 interface. It can be controlled by RS485 equipment from other manufacturers. It can realize the transparent transmission of network data to RS485 data. The baud rate is 300-115200 configurable. When using parity, the data bits must be configured to 9 bits, and the serial port parameters are configured through the configuration tool.
6. The device has a power-down save function, which can save the state of the relay, which can be configured through the configuration tool.
7. Reset the configuration. The RESET position with the silk-screen label is the button to restore factory settings.
Work mode introduction
The working mode is configured with the provided configuration software.
1. TCP server
In this mode, you can only connect to the device through a TCP client, and support 10 TCP client connections.
2. TCP client
In this mode, the device actively connects to the TCP server (the remote IP and remote port number are the 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 communication with remote IP and remote port number (configuration software settings) is supported.
5. DNS domain name
In this mode, the device uses a TCP client to connect to the TCP server of the bound domain name (the port is the remote port).
Command explanation
The above commands are sent and received in character form. There is no carriage return or space after the command. To send in hexadecimal system, check the ASCII code table to convert by yourself.
Get device name
Send:
name
Return:
name="HHC-N8I8OP"
HHC-N8I8OP is the device name, you can use the configuration tool to configure it yourself.
Control the first relay
Send:
on1
Returns:
on1
Close the first relay
Send:
off1
Returns:
off1
The command format is on and off followed by the relay channel, 2-8 channels are controlled as above.
Control all relays
Send:
all00000011
Returns:
relay00000011
All is to control all the relay commands, the following 8 channels are controlled, 1 means to pull in, 0 means to release. The above command means that the first and second channels are pulled in, and the 3rd to 8th channels are released. After this command is executed, the status of the relay is returned. The status return information of the relay is the same as the information returned by the read command.
Delay control
For example, if you want the relay to be closed for 2 seconds and then released, you can send the following command
Send:
on1:02
Returns:
on1
The above command means that the relay will be released after being closed for 2 seconds, on1: represents the relay to be controlled, followed by the delay time, the maximum is 99 seconds, for example, on2:12 means that the second relay is closed after 12 seconds and released. Other 2-8 channel control is the same as above.
Read relay status
Send: read
Return: relay00000001 (representing the status of the 8-way relay, 1 means the relay is closed, 0 means if the relay is released, the above means the first relay is closed, and the 2-8 relays are released)
Read switch
Send:
input
Returns:
input00000001
Input is followed by 00000001, 1 means there is a switch input, 0 means there is no switch input, it means the input state of the 8-channel switch, the above command indicates that the first channel has a switch input, and the 2-8 channels have no switch input. The 9th and 10th switches are used to control the fully open and fully closed relays and cannot be read. The input is configured to "active upload" mode, when the switch input changes, it will automatically send the above return information.
High-speed communication
With high-speed communication, the computer no longer has to wait for data to be sent to the device, and any device can be processed. Working under the TCP server, the device supports 10 TCP clients to continuously send data. Network chips that are not SPI ports such as ENC28J60, W5500 and other chips are comparable, real 100M network ports
Package includes:
1*8 channel network repeater
