2 Port Opto-Isolated RS485 Hub

● The 2-port isolated RS485 hub is designed for industrial use, with complete communication isolation, stable and reliable performance, and a maximum transmission rate of up to 300Kbps.

● Each RS485 channel has a 6kV lightning protection capability, and 2.5KV optocoupler isolation, and it comes with an independent shielded ground interface and LED indicators.

● Automatic data flow control technology allows for automatic identification and control of data transmission direction.

● It supports multi-node communication, with each RS485 channel capable of carrying up to 128 enhanced nodes, and a maximum transmission distance of 1500 meters.

● Each RS485 channel is powered by an isolated voltage of 2500V DC-DC, with high-speed optocoupler isolation for communication signals, achieving electrical isolation between ports.

● The RS485 interface has three levels of lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) short-circuit current wave 10/700μs, open circuit peak output voltage of 6KV, and internal resistance of 40 ohms standard.

● It supports a wide range of 5-70V AC and DC power inputs, with a power interface having a 6kV lightning protection capability.

● The power supply supports overloading and reverse connection protection, and compliance with industrial-grade electromagnetic compatibility requirements.

● Super strong lightning protection function: lightning strike protection, high voltage induction resistance, surge protection, etc.

● Fanless design for efficient heat dissipation, reducing repair time.

● It can be mounted on a rail or wall.

● Working temperature: -40℃ to +85℃.

● It has passed 100% burn-in testing.
