2 Channel DC5V 10A Industrial IP Network Relay Module Remote Controller Ethernet to RS485 Mod-bus HHT-NET2D
Note: This product is mainly used in local area network. For remote control of external network, peanut shell should be purchased, or domain name binding function can be used. Android mobile app can only be used in the local area network, and the traffic cannot be controlled or remote.
1: Product introduction
2-way 10A relay controller, with two-way relay normally open output, without normally closed output, can be used for smart home control, can be used for remote control of electric lights, motors, and other electrical equipment with mobile phones or computers for secondary development, and can provide C + + source code. Reliable network connection, disconnection, router restart, reliable recovery of network connection, remote control across gateways.
2. product parameters
1. Electric voltage, 5V, no less than 1A current.
2.The single function rate of two-way relay is 2kW, the rated voltage of AC load is 250V, and the current is 10A. Rated voltage of DC load is 30V and current is 5A.
3. Appearance size 47.5 * 77 mm.
4. Working temperature - 40 - + 80 ℃.
Four:Product features
1. It works in TCP server, TCP client and UDP mode.
2. Connect 4 clients in the TCP server mode.
3. Modbus TCP protocol, Kingview.
4. Online update program is very convenient for customers to customize the program.
5. It can customize the device name and Chinese definition. When there are many devices, there is no need to record tedious IP number.
6. The heartbeat packet time can be customized and the network can be reliably disconnected for recovery.
7. The 32-bit microcontroller (stm32f103c8) with high-performance Cortex-M3 core is used instead of the 8-bit microcontroller on the market. The network chip adopts the w5500 with hardware protocol instead of the low-cost ones like ENC28J60.
V. very simple control instructions
Send on1 to open the circuit relay, send off1 to close the circuit relay, the second control method is the same. Send read1 to read the status of the circuit relay. If on1 is returned, it means the circuit relay is closed, and if off1 is returned, the circuit relay is released. It can delay control, for example, sending on1:02, which means that the relay is closed for 2 seconds and then released; sending on: 12, which means that the relay is closed for 12 seconds and then released, with a maximum delay of 99 seconds.
Modbus TCP
