UP-485-H4 Industrial RS-232/RS-485 to 4 ports RS-485 Isolation HUB, 2500V Opto-isolation



UP-485-H4 Industrial RS-232/RS-485 to 4 ports RS-485 Isolation HUB, 2500V Opto-isolation. 

Giới thiệu

The UP-485-H4 is an industrial-grade 1-port RS-232/RS-485 to 4 ports RS-485 Hub/Splitter/Repeater with 2500V optical isolation, which can be used to expand RS-485 networks by splitting one RS-485 network into four, and extend the RS-485/422 distance up to 1.2km, effectively avoid damage caused by lightning strikes, surges and other factors.

UP-485-H4 adopts bus segmentation technology to realize star-type centralized network connection of RS-232/RS-485 devices and enhance bus signal load capacity, supports serial data rates up to 115,200bps, auto-sensing and self-adjusting, no DIP switch or jumpers are required, which widely used in intelligent power management, power system automation, water conservancy monitoring, industrial automation, distributed data acquisition and other occasions.

Đặc trưng

  •  Expands RS-485 networks by splitting one RS-485 network into four loops
  •  The failure of any individual loop will not affect the others, making the RS-485 network more reliable

  •  Supports up to 512 (4* 128) nodes of RS-485 devices
  •  Industrial grade rugged ABS housing
  •  Plug and play (hot-pluggable)
  •  Built-in 600W surge protection, 15kV static protection and circuit protection
  •  Support 2500V optical isolation
  •  Supports high-speed serial data rates: 300 to 115200bps
  •  External DC5V or DC9-30V
  •  Data direction auto-turnaround, no software drivers or flow control is required
  •  Support DIN-Rail or wall mount installation
  •  Working temperature range:-40~85°C
