3.5mm Terminal Connector with Power Isolation: This 485 opto isolated hub adopts sturdy 3.5mm terminal blocks compatible with OK wires and fly wires for reliable connections. Onboard power isolation achieves electrical isolation between input and output terminals, significantly enhancing system anti-interference capability in industrial environments.
Complete Optical Isolation for Device Protection: The onboard optical isolation effectively separates RS485 master and slave devices, protecting them from damage caused by ground potential differences, static electricity, and voltage surges. This design minimizes ground loop issues between connected devices, ensuring stable and reliable communication.
Comprehensive Overcurrent and Surge Protection: Each 485 terminal includes overcurrent protection, surge protection, and gas discharge protection circuits to ensure reliable operation even in harsh electrical environments. This multi-layer protection safeguards your valuable equipment from unexpected power fluctuations and transient voltages.
Terminal Resistor Switch for Signal Stability: Features a convenient DIP switch for selecting the onboard 120Ω termination resistor, allowing customization based on actual installation needs. This helps enhance signal transmission stability and reduce interference, especially in long-distance communication setups up to 1200 meters.
High Baud Rate with LED Status Indicators: Supports baud rates up to 1 Mbps (subject to connected device limitations) for fast data transmission. Each port supports up to 32 nodes, and multi-channel LED indicators clearly display power supply status and signal transmission/reception status for easy troubleshooting and monitoring.
