Product Description

HHC-N8I8OP 8-way Network Relay RS485 to Ethernet Switching Controller MOD-BUS TCP IP Relay

Description:

Product Introduction:

This product is resistant to high temperature and can work at -40 degrees to positive 85 degrees. Strong anti-interference ability, can be connected to external high-current AC contactors and relays, will not crash under strong electromagnetic interference. True 100M speed, reliable communication in the case of zero-delay command. Industrial grade products. Automatically obtain IP addresses. 10 TCP client connections are supported under the TCP server. Through the provided configuration software, you can configure five working modes: TCP server, TCP client, UDP server, UDP client, and DNS domain name. It has one RS485 port and supports transparent transmission from Ethernet to RS485. 8 relay, 8 switch input, with full on and full off input. Power-off save function (save relay status).


Electrical parameters:

Power supply DC 7-24 volts, can choose DC block or terminal input power, DC connector specifications 5.5-2.1MM (outer diameter - inner diameter).
Board operating temperature range -40 ° C to 85 ° C.
8 independent relay outputs, output without voltage. A single relay has a DC rating of 10A, an AC rating of 10A, a maximum AC rating of 250V, and a maximum DC rating of 30V.
10 Channel independent input. IN9 indicates that all relays are on, IN9 has a switch input, all relays are on, IN10 indicates that all relays are off, when IN10 has a input, all relays are off. IN1-IN8 You can configure the eight input modes by using the parameter configuration tool. In the Input mode section of the configuration tool, select three different working modes. "Normal input" mode Generally collects input signals. To obtain input status, a command to read input status is sent to the device. "Trigger relay" mode, this mode has input, the corresponding relay status flipped, IN1-IN8 control corresponding to 1-8 relays. Active Upload mode: In this mode, when the input status changes, the system automatically sends the input status to the network connected to the device.
The device has an RS485 interface. Can be connected to other manufacturers of RS485 equipment for control. The baud rate of 300 to 115200 can be configured. When the parity check is used, the data bit must be set to 9 bits. The serial port parameters can be set using the configuration tool.
The device has a power down save function, which can save the status of the relay, which can be configured through the configuration tool.
Reset the configuration. The silk screen label RESET indicates the reset button.

Working mode introduction:

The working mode is configured using the configuration software provided.

1. TCP server

In this mode, devices can only be connected through TCP clients, and 10 TCP client connections are supported.

2. TCP client

In this mode, the device actively connects to the TCP server (remote IP and remote port number are parameters for the device connection). Only one server can be connected.

3. UDP server

In this mode, arbitrary 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 uses a TCP client to connect to a TCP server bound to a domain name (the port is a remote port).

High Speed communication:

High-speed communication, the computer to the equipment to send data no longer have to wait, just send the equipment can handle it. Working on the TCP server, the device supports 10 TCP clients to send data without interruption. It is not comparable to SPI port network chips such as ENC28J60, W5500 and other chips. Real 100M network port.



Command interpretation:

The preceding commands are sent and received in character format. No car after the command, no space. To 16 to check the ASCII code table to convert itself.



Get device name

Send: name

Return: name="HHC-N8I8OP"

Hc-n8i8op is the device name, which can be configured by using the configuration tool.



Control 1 relay

Send: on1

Return: on1



Turn off the first relay

Send: off1

Return: off1

The command format is on and off followed by relay channels. For 2-8 control channels, see the above.



Control all relays

Send: all00000011

Return: relay00000011

all is the command that controls all relays. The following eight commands are used. 1 indicates that the relay is switched on and 0 indicates that the relay is switched off. This command returns the status of the relay, and the status of the relay returns the same information as the read command.



Delay control

For example, if you want the relay to close for 2 seconds and then release, you can issue the following command

Send: on1:02

Return: on1

The above instruction indicates that the relay is released after 2 seconds of suction, on1: indicates the relay to be controlled, followed by a delay time, a maximum of 99 seconds, for example, on2:12 indicates that the second relay is released after 12 seconds of suction. The other 2-8 controls are the same as above.



Read relay status

Send: read

Return: relay00000001(indicates the status of the 8-way relay, 1 indicates the relay is drawn, 0 indicates that if the relay is released, the above indicates the first relay is drawn, and the 2-8 relay is released)



Read switching quantity

Send: input

The command output is input00000001

Input followed by 00000001, 1 indicates that there is a switch input, 0 indicates that there is no switch input, and indicates the input status of 8 switches. The above command indicates that there is a switch input in the first line, and there is no switch input in 2-8 channels. The 9th and 10th switches are used to control the full on and full off of the relay and cannot be read. The input mode is set to Active upload. When the switch changes and the input changes, the system automatically sends the above message.
