8 Channel Network Relay Module IP/ Ethernet Access Controller Switches Transmit MOD-BUS TCP
Note:
1. The power interface on this board has been changed from the previous 5.5-2.1MM to 5.5-2.5MM, especially those with their own power supply should pay special attention.
2. This product is mainly used in the local area network, the remote control of the external network to buy peanut shells, or have their own domain name binding function to use. What we provide is computer control, and mobile APP needs to be developed by ourselves.
3.Product update: GD32F103C8 is used, and the network chip is W5500 which is a hard protocol.
Product description
8 10A relay controllers with normally open and normally closed outputs. 8 switch inputs. Can be used for smart home control, can be developed with mobile phones or computers remote control lights, motors, and other electrical equipment. It can also be used for power failure detection in the computer room, can be connected to the human infrared sensor, can be connected to the key switch, can be connected to the smoke alarm output. C++ source code available. Reliable network connection, network disconnection can be automatically reconnected. In the TCP service mode, it can support 4 network connections (only one network connection is supported on the market), using a 32-bit single-chip microcomputer (STC8-bit single-chip microcomputer on the market), which is a very convenient network parameter setting software. Supports MODBUS TCP and can connect with Kingview.
Product features
1, support to work on the TCP server. TCP client in UDP mode.
2, work in TCP server mode to support 4 client connections.
3, support MODBUS TCP protocol, support Kingview.
4, support online update program, very convenient for customers to customize the program.
5, can customize the device name, support Chinese definition, when many devices do not need to record cumbersome IP number.
6, can customize the heartbeat packet time, reliable network recovery.
7, the use of high-performance Cortex-M3 kernel of 32-bit MCU (STM32F103C8), rather than the market 8-bit MCU, the network chip is the hardware protocol of W5500, rather than ENC28J60 these low-cost.
8, can work in the switch metering transmission mode.
9, there are three firmware, downloaded through the configuration project, respectively, universal firmware, switch transmission firmware, access control firmware. Universal firmware is operated in slave mode, by command control, switching through the firmware, is used in pairs, where the input of one controls the output of the other, and each input controls the output of the other relay. Access control firmware, can connect to four Wiegand 26 protocol read heads.
10. Commands supported by MODBUS TCP: 01 read relay status, 05 operate a single relay, 0f operate all relays, 02 read switch input.
Product parameters
Power supply: DC 7-24V, power supply is not less than 2A.
Output: 8 relay outputs, each with a maximum power of 2kW, rated AC load voltage of 250 volts, current of 10A. Dc load rated voltage 30V, current 5A, no voltage output, the output is the relay switching quantity.
Input: Input switching quantity, passive or active, active maximum 5V.
Network parameters: can be controlled across the gateway (to set routing and forwarding), remote control to solve the dynamic IP problem by itself (the public IP address assigned by the router is different each time the router is started).
Very simple control instructions
Send on1 to open the first relay, send off1 to close the first relay, the 2-8 control method is the same. Send read Indicates the status of the relay. For example, relay00000001 is returned, indicating that the first relay is engaged and the relays 2-8 are disconnected. Time delay control, for example, sending on1:02, indicates that the relay is released after 2 seconds, sending on:12 indicates that the relay is released after 12 seconds, and the delay is up to 99 seconds.
Product use
Can be used for access control, control computer open, remote control electrical appliances, can be connected to smoke alarm output, can be connected to human infrared output, can be connected to key switch, can be connected to any passive switching input, can also be connected to active switching input (connected to 5V active switching). It can be controlled by external network or remote control by mobile phone (mobile APP should be developed by itself).
