Product Description
Product features:
Passive RS485 interference device is a solution for RS485 passive isolation filter requirements and design of RS485 system in complex electromagnetic environment, the broadband industry leading anti-jamming technology with high transient isolation, suppression of common mode interference amounted to 118dB (CMRR), the product supports transmission rate up to 1MBPS, transmission distance is greater than 1200 m, stable performance. The application of common mode signals for industrial frequency motor data communication, data security strong electromagnetic environment interference, but also widely used in highway toll system, road monitoring system, city communications and power engineering data acquisition system, is a kind of outstanding performance, excellent price data interface conversion anti-jamming and interface protection products.
This product without additional power supply, no additional sending and receiving control signals, only A/B signal, zero delay automatic transceiver conversion technology combined with the internal unique, support RS422 full duplex and RS485 half duplex mode, ensure that the format is compatible with all RS485/422 hardware and software communication! For interface protection and strong anti-interference, suggest the user connects to RS485 source (client) and end node (PC), used to remove high frequency surge spikes due to strong electromagnetic interference on the RS485 machine impact or damage. Passive RS485-422 broadband anti-interference isolator can work in strong interference environment, which can ensure the control data to the normal communication, and video loop interference device can be used to eliminate the stripes on the video image and moire interference.
RS485 protector anti-interference one-way passive isolator RS485 RS485 isolation (can be used by 2 parallel equipment for RS422 applications)
Product application:
The product design is exquisite, the wiring is simple, the use is convenient. Widely used in industrial monitoring, civilian Yuntai monitoring, and industrial control equipment etc.. LED display data communication (many display company has used, almost all manufacturers compatible control card, after the test are very good); more suitable for machine tool PLC to read and write data; monitoring data read and write and tilt control; Home Furnishing electrical control; control system; card; industrial automation; instrumentation; parking lot; bus charge; dining service system; attendance machine; highway toll station; ATM; etc.......
Product features:
1, the scope of work can be as wide as -45 to +85 degree of industrial temperature
2, without any photoelectric type of temperature drift and additional power noise
3, no additional power supply and alternative electricity type passive Optocoupler
4, RS485 photoelectric isolator due to the two interference by introducing power supply
5, the transient response of passive RS485/422 isolator has excellent 12nS
6, the standard RS485/422 line impedance matching, the return loss is greater than 18dB
7, low insertion loss, less than 0.8dB
8, working temperature range: -45 degrees to +85 degrees
9, size: 65X38X22mm
Special tips:
RS485/422 anti interference filter equipment is mainly used to control the data of the anti electromagnetic interference separation applications, high access resistance to support multi bus node equipment and access. (more than 500 meters in the long distance and the connection to ensure the stability of data communications, the proposed input front-end with active RS485 repeater
