Local Change HUB 4 Ports RS-485/422 (UT-1304)

 

With RISC design, UT-1304 is a RS-485/RS-422 hub, suit for large RS-485/RS-422 system under complex environment. Baud rate: up to 115.2 KBPS. With delicate built-in protection, 3,000A surge protection; isolation voltage: 2,500V; well protected from lightning strike and ESD. Outdoor usage Under RS-485/RS-422 mode, auto-adapt data stream. Max: 1.2km. Widely using at express way toll system, road monitoring system with excellent performance and competitive prices. RS-485/RS-4 22 star topology bus connection is provided by UT-1304 RS-485/RS-422 HUB. Photoelectric isolation of 2,500V is provided. Re-construction of RS-485/422 bus structure and network range splitting can be easily realized to improve communication reliability. In the case of lighting strike or equipment failure, the affected range shall be isolated to make sure the normal function of other ranges. This feature can increase greatly the reliability of existing RS-485/RS-422 with achievement of shorter time for network maintenance. Proper application of UT-1304 RS-485/RS-422 HUB can help you to design a high stability RS-485/RS-422 system.
