H01 THREE-WAY Isolated RS485 HUB 1:3 3kV DC Isolation
H01 THREE-WAY Isolated RS485 HUB 1:3 3kV DC Isolation
- Three-Way Isolated RS485 1:3 HUB 3kV DC Isolation 1x In 3x Out
Product description
Redisage's H01 is a reliable RS485 signal HUB made to work with variable transmission speeds up to 115200 bps. It allows flexible branching of the 1:3 interface while simultaneously protecting the attached devices with a 3 kVDC three-way isolation. Additionally, a dedicated EMC protection circuit improves transmission quality in an industrial environment. H01 is powered with 12-30 VDC or 24 VAC and ensures low power consumption of less than 1W.

About H01
Need stability and reliability in your RS485 network? The H01 three-way RS485 Hub can get the job done easily thanks to its 1-to-3 signal distribution, which makes it incredibly efficient at expanding communication lines while maintaining full data integrity. The 3kV isolation provides robust protection against electrical surges, safeguarding whatever devices are plugged in between the input and output.
Our hub supports automatic RS485 direction control, eliminating the need for manual configuration. Additionally, built-in ESD protection means electrostatic discharges won’t cause problems or threaten network stability. Your devices will also enjoy higher longevity, which is a must in demanding technical environments.
Technical Specifications of Three-way RS485 isolated HUB:
- Three-way 3kV isolation
- 1-to-3 RS485 signal distribution
- Automatic RS485 direction control
- ESD protection for enhanced durability
- Power supply: +12 to +30 V/DC or 24 V/AC
- Baud rate: up to 115.2 kbps
These devices are perfect for industrial automation when you need the network to run itself hands-off. The larger the scale of your RS485 network, the more invaluable the H01 hubs become—just remember to account for any conversion needs and pick up the right number of RS232 converters as well to ensure your network functions properly. Also, given their high electrical interference resistance, the H01 RS485 three-way hub performs exceptionally well whenever stable data transmission and low risk of signal loss or degradation are required.
