PoE Hirschman Switch for Industrial Switches

With the development of industrial Internet technology, network terminal devices (cameras, wireless APs, etc.) are becoming more and more abundant. Before the emergence of PoE (Power over Ethernet) technology, the power supply method for network terminal devices is generally to use separate power lines and power sockets. In practical construction operations, it is tedious and complex, often resulting in an increase in overall costs due to the inability to find suitable socket installation points. How to achieve power supply and communication for network terminal equipment in a convenient way on industrial sites? With the emergence of industrial switches supporting PoE, the issues of power and network cabling for on-site terminal devices can be effectively solved by using Ethernet Cat.5 cabling infrastructure, while also providing DC power to terminal devices and transmitting data signals.

Where is PoE located?

1. Simplified wiring: Compared with conventional industrial switches (as shown in the schematic diagram), industrial switches that support PoE function can simultaneously transmit data and complete terminal device power supply with one Ethernet cable, saving power line costs and the required accessory materials for installing power lines. The installation is convenient, and the equipment can be moved freely, saving labor costs and time, and saving system maintenance costs.

2. Safe and reliable: Industrial switches that support PoE function will only supply power to devices that require it. Only after the power supply device and the receiving device complete the handshake protocol, will the PoE powered device output voltage, eliminating the risk of leakage on the line. Users can safely mix non PoE devices and PoE devices on the project and coexist with existing Ethernet cables.

3. Efficient and stable: Industrial switches that support PoE functionality support two types of standards: IEEE802.3.af (PoE) and IEEE802.3at (PoE+). PoE+supports remote power supply technology and can provide power to network terminal devices up to 100 meters or even farther away through Ethernet cables. The scientific voltage management system uses 24V or 48V DC power supply at the power supply end, and the terminal equipment uses electricity according to the required voltage, while also improving the stability of network terminal equipment.
