RS485 Maximum Cable Distance & Extension Solutions: 2026 Standards
The RS485 maximum cable distance under the TIA/EIA-485-A international standard is 1,200 meters (4,000 feet) at baud rates below 100 kbps, and extending telemetry across expansive industrial campuses requires specialized hardware solutions: optically isolated RS485 repeaters, multi-channel isolated RS485 hubs, or RS485 to Ethernet/Fiber gateways that route serial data over optical backbones. In manufacturing complexes […]
