R01 - RS485 Repeater (3-Way 3kV Isolation)
R01 - RS485 Repeater (3-Way 3kV Isolation)
- High-performance active RS485 repeater with full 3-way galvanic isolation (Power/Input/Output) for maximum interference protection.
Product Description
The Redisage R01 is an industrial RS485 repeater designed to extend network reach and ensure signal integrity in electrically noisy environments. It features full 3-way galvanic isolation (3000 VDC), meaning the input, output, and power supply are all electrically separated from each other.
This device regenerates the RS485 signal, allowing you to double the maximum cable length (another 1200 m) and add 32 more nodes to the bus. Key features:
• Isolation: 3-Way (Eliminates ground loops)
• Control: Automatic RS485 Direction Control
• Function: Signal amplification & Range extension
• Power Supply: 12-30 VDC
• Speed: Transparent up to 115200 bps
• Protection: ESD on data lines

About R01
R01 – Maximum Reliability for RS485
The R01 RS485 Repeater is the ultimate shield for your industrial network. While standard repeaters simply amplify the signal, the R01 provides a complete 3-way galvanic isolation barrier (3000 VDC). This unique architecture ensures that the Input side, Output side, and Power Supply are all electrically decoupled, preventing high-voltage surges and ground loops from propagating through the system.
In addition to protection, the R01 acts as a signal booster, restoring the voltage levels of the RS485 data stream. This allows you to extend the network by an additional 1200 meters and connect another 32 devices. The device utilizes Automatic Data Direction Control (ADDC) for data flow.
Technical Specifications:- Isolation Type: 3-Way (Input || Output || Power).
- Interfaces: RS485 to RS485 (2-wire).
- Power Supply: 12–30 VDC.
- Mounting: DIN-rail (TS-35).
Secure your critical infrastructure with the R01. Wiring diagrams are available in the user manual.
