tyle="display:mangofig"> modname=ckeditor Product Name:Super strong RS485 anti-jamming /RS485 isolation filter / variable frequency motor data protection / repeater Product features: Passive RS485 anti-jamming device is a passive RS485 isolation filter designed for solving the requirements of RS485 large system in complex electromagnetic environment. It adopts the industry leading broadband high transient isolation anti-jamming technology and achieves 118dB common mode interference suppression (CMRR). The product supports the transmission rate up to 1MBPS and the transmission distance is greater than that of the interface. 1200 meters, stable performance. It is applicable to the anti-interference application of the common mode signal in the data communication of industrial frequency conversion motor and the security data under the ultra strong electromagnetic environment. It is also widely used in the expressway toll system, road monitoring system, urban engineering data communication and electric power acquisition system, which is an excellent performance and high price data interface conversion anti-interference. And interface protection products. There is no extra power supply, no extra receipt and control signal, only A/B signal can be used, plus the unique internal zero delay automatic transfer and transfer technology, support RS422 full duplex and RS485 half duplex mode, to ensure compatible all formats of RS485/422 hardware and software communication! In view of the protection of the interface and the ultra strong anti-interference application, the users are proposed to be connected to the RS485 source end (lower computer) and the node end (upper computer) to remove the impact or damage of the high frequency peak surge caused by strong electromagnetic interference on the RS485 and the lower computer.The passive RS485-422 wideband anti-jamming isolator can work in a strong interference environment, which can ensure the normal communication of the control data, and the interference with the video and ground loop isolator can be used to eliminate the cross pattern and the reticulated interference on the video image. Single channel passive RS485 isolator RS485 isolation anti-jamming RS485 protector (2 devices can be used in parallel for RS422 application). | Product application: The product is ingenious in design, simple in wiring and easy to use. It is widely used in industrial monitoring, civil platform monitoring, industrial equipment control and other fields. LED display communication data (many display companies have batch use, almost compatible with all manufacturers control card, after testing are very useful); more suitable forPLC data reading and writing of machine tool;Monitoring data reading and writing and control of cloud platform;Household electrical appliances collection and control;Entrance guard system; one card;Various industrial automation; instruments and instruments;Parking lot; bus charge;Dining room system; staff attendance machine;Freeway toll station; ATM; etc.…… Product features: 1, the working range can be extended to -45 to +85 degree industrial grade temperature. 2, no photoelectric temperature drift and additional power noise. 3. No need for extra power supply and passive optical coupling instead of electric larceny type. 4. The two interruption of the photoelectric isolator without RS485. 5. Passive RS485/422 isolator has excellent transient response to 12nS. 6, standard RS485/422 line impedance matching, return loss greater than 18dB 7, low insertion loss, less than 0.8dB 8. The range of working temperature: -45 degree to +85 degree 9. Size: 65X38X22mm Special hints: RS485/422 anti-jamming filter equipment is mainly used to control data anti-electromagnetic interference isolation applications, high access impedance support multi-bus node equipment parallel connection. In order to ensure stable data communication (more than 500 m long distance and multiple contacts), it is recommended to install an active RS485 repeater at the input front end. | -->
