Common Pain Points in RS485 Bus Applications
In large-scale RS485 deployments for industrial sites, buildings, security, and energy collection, users frequently face these issues: excessive device load overwhelming the bus, limited communication distance, frequent signal interference, complex and error-prone wiring, poor stability in harsh environments, difficult expansion, and high maintenance costs.
Solution
1.1-to-8 Multi-Channel Expansion: One master connects up to 8 slaves with bidirectional transparent transmission, enabling fast construction of distributed networks.
2.1500V Photoelectric Isolation + Multiple Protections: Complete input-output isolation (1500V), built-in overcurrent, overvoltage, reverse polarity, and 1500V surge protection for superior anti-interference performance.
3.Up to 1200m Stable Communication: Standard RS485 bus distance supports large-scale deployments (add a repeater when exceeding 32 devices or 1200m).
4.Industrial-Grade Wide Temperature & Voltage Design: DC 7–30V wide voltage input, -40°C to +85°C full-range operation, reliable in extreme conditions.
5.Plug-and-Play, Zero Configuration: Fully compatible with Modbus RTU protocol, seamless integration with SCADA systems, IoT gateways, and cloud platforms for rapid deployment.
