Reliable Isolation and Signal Amplification
The R04 is built for industrial-grade RS232 networks that require signal boosting and galvanic isolation. It eliminates the risk of voltage differences or ground loops between connected devices by isolating one side of the transmission. This makes it ideal for environments where surge protection and system separation are crucial.
Thanks to one-way optical isolation, the device transmits data safely in one direction, helping prevent feedback loops or electrical damage in sensitive setups. Its compact DIN rail enclosure ensures it fits easily into control panels or communication cabinets.
