Industrial-grade large-sized electrical terminals provide stable and reliable contact. Protects against EMI interference from frequency converters and PLCs to ensure data integrity. Reduces signal surges, resists RFI and electromagnetic interference, and prevents damage from overvoltage. The 485 anti-interference device connects in series on the signal line. Passive RS485-422 broadband isolator operates reliably in strong interference environments and ensures stable control data communication. Product application: Features a refined design, simple wiring, and easy installation. Widely used in industrial monitoring, civil PTZ monitoring, and industrial equipment control systems. Features: - Operating temperature range: -45°C to +85°C - No photoelectric type temperature drift or additional power supply noise - No external power supply required; uses passive optocoupler technology - Eliminates secondary interference caused by power supply in traditional RS485 photoelectric isolators - Passive RS485/422 isolator with 12ns transient response - Standard RS485/422 line impedance matching, return loss 18dB - Low insertion loss: less than 0.8dB - Operating temperature range: -45°C to +85°C - Material: Plastic and metal - Color: Black and blue Package Contents: 1 x RS485 Anti-Interference Device Note: The package includes only the items listed above.
