Aundhegrtt Industrial Passive RS485 Isolator Communication Data Stabilizer PLC Anti-Interference Filter Protection

The passive RS485 isolation filter adopts industry-leading wideband high transient isolation and anti-interference technology, achieving a total of 118dB mode interference reduction (CMRR). This product supports a maximum transmission rate of 1Mbps, an interface transmission distance 1200 meters, and stable performance. Suitable for anti-interference applications of common-mode signals in industrial variable frequency motor data communication and security data in ultra-strong electromagnetic environments. It is also widely used in highway toll systems, road monitoring systems, urban engineering data communication, and power acquisition systems. For interface protection and strong anti-interference applications, it is recommended that users connect it separately to the RS485 source end (lower device) and node end (upper device) to the impact or damage to the RS485 upper and lower devices caused by high-frequency spike surges due to strong electromagnetic interference. It requires no external power supply or additional transmit/receive control signals; only A/B signals are Combined with its internal zero-delay automatic transmit/receive conversion technology, it supports RS422 full-duplex and RS485 half-duplex modes, ensuring compatibility with all RS485/422 hardware and software communication formats! The passive RS485-422 broadband anti-interference isolator can operate in strong interference environments, ensuring normal communication of control data. When used in conjunction with a video ground loop isolation anti-interference device, it can horizontal and grid patterns in video images.
