About this item

• Feature: 1. Support working in TCP server, TCP client and UDP mode 2. Working in TCP server mode supports 4 client connections. Support for MODBUS TCP protocol, support for KingView 3. Support online update program, very convenient for customers to customize the program 4. Can customize the device name, support Chinese definition, do not need to record tedious IP when there are many devices 5. Userdefined heartbeat packet time, reliable network recovery 6. A 32bit singlechip microcomputer with a highperformance for CortexM3 core is used, and the network chip is a W5500 with a hardware protocol 7. 2channel 10A relay controllers, with normally open output without normally closed output, can be used for smart home control, and can be used to remotely control electric lights, motors, and other electrical equipment using mobile phones or computers for secondary development 8. Provide host computer C ++ source code, reliable network connection, router restart after disconnection, reliable network connection recovery, remote control across gateways 9. 5V power supply for this product, with two relays normally open output, without normally closed output Specification: Item Type: IP Network Relay Module Current: Not less than 1A Size: Approx. 81 x 50 x 31mm 3.2 x 2 x 1.2in Operating Temperature: 40 celsius to 80 celsius . Applications: 1.Can be used for smart home control, control router restart after network disconnection, etc. 2. It can remotely control electric light, motor, and other electric equipment using mobile phones or computers for secondary development. 3. Can be used for power failure detection in the computer room, can be connected to human body infrared sensors, can be connected to key switches, can be connected to smoke alarm output. 4. Can be used for access control, computer control, remote control of electrical appliances 5. Can be connected to smoke alarm output, can be connected to human body infrared output 6. 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). 7. Can be controlled by external network, and can be controlled remotely by mobile phone. Control Instruction: Send: on1 turns on the first relay Send: off1 turns off the first relay; the second control method is the same. Send: read1 means to read the state of the first relay. If it returns on1, it means that the first relay is on, and off1 means that the first relay is off. Delay control, such as Send: on1: 02 Means That The Relay Will Open After 2 Seconds, and send on: 12 means that the relay will open after 12 seconds. The maximum delay is 99 seconds. For MODBUS TCP 1.01 opcode This operation code is to read the state of the relay. The relay address is 0010 on the first channel and 0011 on the second channel. 2.05 opcode This operation code is to control a single relay. The relay address is 0010 on the first channel and 0011 on the second channel. 3. 0F opcode This Operation Code Is To Control Two Relays. The Relay Addresses are: No. 0010, No. 0011.. Package List: 1 x IP Network Relay Module(with case) Note: This product is mainly used in the local area network. The remote control of the external network requires the purchase of PeanutHull or the domain name binding function. The for Android mobile APP can only be used in the local area network. The dataflow cannot be controlled and cannot be remote.Support working in TCP server, TCP client and UDP mode Working in TCP server mode supports 4 client connections. Support for MODBUS TCP protocol, support for KingView Support online update program, very convenient for customers to customize the program Can customize the device name, support Chinese definition, do not need to record tedious IP when there are many devices Userdefined heartbeat packet time, reliable network recovery
