ABB NE802;  NE802 Network switch 3BSE080237R1

ABB NE802 (product number 3BSE080237R1) is a 5-port unmanaged network switch designed specifically for industrial application scenarios, playing an important role in industrial network construction.

Port configuration

It has one SFP fiber port and four copper cable ports, all of which support 10/100 Mbit/s or Gigabit Ethernet connections. Among them, SFP fiber ports can flexibly adapt to ABB's rich range of small form factor pluggable (SFP) transceivers, including multi-mode, single-mode, or bidirectional transceivers, with a transmission distance of up to 120 km, which can meet the long-distance and high-speed data transmission needs in different scenarios; The four copper cable ports provide convenience for common device access.

Power supply design

The switch is equipped with dual 10 to 57 VDC power inputs, which greatly enhance the power supply stability of the equipment in industrial environments. Even if one power supply fails, the other can still ensure the normal operation of the equipment. At the same time, the unique "three electric isolation" technology achieves isolation between all ports, power supplies, and shielding layers of each chassis, effectively avoiding interference from grounding loop currents on equipment operation.

Protection and Durability

From the perspective of protection level, NE802 meets the IP21 standard, which means it can be installed in places where condensation may occur, providing effective protection for internal circuits. In terms of durability, it only uses industrial grade components, with an average time between failures (MTBF) of up to 1182000 hours, ensuring that the equipment has a long service life. In addition, the switch has a wide operating temperature range, stable operation between -40 to+70 ° C (-40 to+158 ° F), and no moving parts inside, reducing the risk of failure caused by mechanical wear and tear.

Other characteristics

Automatic MDI/MDI - X Crossover: The port has automatic recognition and configuration functions, which can automatically adapt to the type of connected device without manually adjusting the network cable connection method, simplifying the installation and debugging process.

LED indicator lights: Equipped with power, speed, duplex, link, and flow LED indicator lights, users can intuitively understand the working status of the equipment through these indicator lights, making it easy to quickly troubleshoot faults.

Installation method: Supports 35mm DIN rail installation, convenient for installation and deployment in industrial control cabinets and other environments, saving space and ensuring stable installation.

Flow control function: Flow control can be enabled or disabled according to actual needs to optimize network traffic, ensure the stability and efficiency of data transmission.

In summary, the ABB NE802 network switch, with its excellent port configuration, reliable power and protection design, good durability, and rich practical features, has become a trusted basic equipment in industrial network construction, providing stable and efficient network connection support for fields such as industrial automation.
