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 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 high-noise environments and ensures uninterrupted control data communication. Product application: Features a compact design with simple wiring and easy installation. Widely used in industrial monitoring, civil PTZ camera systems, and industrial equipment control. 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-stealing methods in traditional RS485 photoelectric isolators - Passive RS485/422 isolator with fast 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: Other items not included. Note: Lighting and display differences may cause slight color variations. Measurement error allowed: +/- 1-3 cm.
