Item Type:Network Relay_x000D_ Power Supply:DC7~24V(DC socket or wiring terminal can be selected to input power.)_x000D_ DC Connector Size:5.5 x 2.1mm / 0.22 x 0.08in (Outer Diameter - Inner Diameter)_x000D_ Working Temperature Range:-40~85_x000D_ Users Manual:_x000D_ 8 independent relay outputs_x000D_ The output does not have voltage. The single relay has a DC rating of 10A, an AC rated current of 10A, a maximum AC rating of 250V, and a maximum DC rating of 30V._x000D_ 10 channels of independent input_x000D_ IN9 means full open, after IN9 has digital input, all relays are connected._x000D_ IN10 means full off. When IN10 has output, all relays are off._x000D_ The 8-input user of IN1-IN8 can be configured into three different working modes through the configuration parameter tool, and is selected under the Input Mode of the configuration tool._x000D_ In the "normal input" mode, the ordinary input signal is acquired. To obtain the input status, a command to read the input status is sent to the device._x000D_ "Trigger Relay" mode, after this mode has input, the corresponding relay state is reversed, and the IN1-IN8 control corresponds to the 1-8 relay._x000D_ Active Upload mode, which actively sends an input status to the network connected to the device when there is a change in the input._x000D_ The device has an RS485 interface. It can be controlled by RS485 equipment from other manufacturers. Can realize the transparent transmission of network data to RS485 data, the baud rate 300-115200 can be configured. When using parity, the data bit must be configured to 9 bits, and the serial port parameters are configured through the configuration tool._x000D_ The device has a power-down save function that saves the status of the relay and can be configured through the configuration tool._x000D_ Reset the configuration. The label RESET position is the factory reset button._x000D_ Working mode introduction_x000D_ The working mode is configured with the provided configuration software._x000D_ 1, TCP server_x000D_ In this mode, the device can only be connected through the TCP client and supports the connection of 10 TCP clients._x000D_ 2, TCP client_x000D_ In this mode, the device actively connects to the TCP server (remote IP and remote port number are parameters for device connection). Only one server can be connected._x000D_ 3, UDP server_x000D_ In this mode, any UDP communication is supported._x000D_ 4, UDP client_x000D_ In this mode, only UDP communication is supported for remote IP and remote port number (configuration software settings)._x000D_ 5, DNS domain name_x000D_ In this mode, the device connects to the TCP server (the port is the remote port) that binds the domain name with a TCP client._x000D_ _x000D_ Command interpretation_x000D_ The above commands are sent and received in characters. There is no carriage return after the command, no spaces. To be hexadecimal, you need to check the ASCII code table to convert itself._x000D_ _x000D_ Get device name_x000D_ Send: name_x000D_ Return: name="HHC-N8I8OP"_x000D_ The HHC-N8I8OP is the device name and can be configured using the configuration tool._x000D_ _x000D_ Control the first relay_x000D_ Send: on1_x000D_ Return: on1_x000D_ Turn off the first relay_x000D_ Send: off1_x000D_ Return: off1_x000D_ The command format is on and off followed by the relay channel, and the 2-8 control is the same as above._x000D_ _x000D_ Control all relays_x000D_ Send: all00000011_x000D_ Return: relay00000011_x000D_ All is to control all relay commands, the latter 8 channels control, 1 means pull-in, 0 means to loosen the above command to indicate that the first road is connected with the second road, and the third road is released. After this instruction is executed, it returns to the state of the relay. The status information of the relay is the same as the information returned by the read command._x000D_ _x000D_ Delay control_x000D_ For example, if you want the relay to pick up and then release it for 2 seconds, you can send the following command._x000D_ Send: on1:02_x000D_ Return: on1_x000D_ The above command indicates that the relay is released after 2 seconds of pull-in, on1: indicates the relay to be controlled, followed by the delay time, maximum 99 seconds, for example, on2:12 means that the second relay is released after 12 seconds of pull-in. The other 2-8 controls are the same as above._x000D_ _x000D_ Read relay status_x000D_ Send: read_x000D_ Return: relay00000001 (represents the status of the 8-way relay, 1 means the relay is closed, 0 means that if the device is released, the above indicates that the first relay is closed, and the 2-8 relay is released)_x000D_ _x000D_ Reading switch_x000D_ Send: input_x000D_ Return: input00000001_x000D_ Input followed by 00000001, 1 means there
