Data Sheet RS485 HUBs (H01 - H03) H01 H02 H03 Features Isolated RS485 1:3 HUB ESD protection for the RS485 data line Power supply: +12 to +30 VDC or 24 VAC 3000 VDC isolation protection Transmission speed up to 115200 bps Tx, Rx and power LED indicators RS485 embedded termination 120 ohm Operating temperatures: -40°C to +75°C DIN-rail mounting Compact size - single module format (1M) Dimensions: 90x56.4x22.5 mm 3 years warranty Customization of OEM is welcomed Introduction The products from the H01-H03 family are reliable RS485 signal hubs made to work with variable transmission speeds. They allow flexible branching of the 1:3 interface while simultaneously protecting the attached devices thanks to internal 3 kV/DC galvanic isolation. Additionally, dedicated EMC protections will improve transmission quality and limit the impact of interference typical for an industrial environment.

Redisage Electronics modules feature a design for the frame ground terminal block FG. The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable. Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD. Frame Ground FG connection reference drawing is provided below. If earth ground is not available FG can be left floating or it can be connected with the power supply GND.
