Photoelectric isolation active RS232 to RS485 interface converter lightning protection | Инструменты

Active isolation type, RS485 has super strong driving ability.       Active type, DC 9-30V wide voltage input, US ON original imported voltage regulator, ultra-low heat, maximum current 40mA.       Jinshengyang second-generation DC-DC isolation module is adopted, which is super stable. Absolutely authentic Jin Shengyang module, original purchase.       High-speed octapod optocoupler imported from American Fairchild is used for super communication speed.       The baud rate is self-adaptive and fully transparent. It can be used immediately after connection, without any setting.       Both ends of RS232 and 485 are protected by lightning protection tubes, with zero damage and zero maintenance.       RS232 can be directly connected to the computer. The extension cable can be male to female (one male and one female).     RS232 end adopts 3-wire system, namely 2,3,5 feet. Pin 5 is the ground pin and the ground of the 232 interface. Not the earth. Can't pick up the earth.           Industrial-grade optically isolated interface converter, compatible with RS-232 / RS-422 / RS-485 standards, can convert single-ended RS-232 signals into balanced differential RS-485 signals, built-in optical isolator and DC / DC DC voltage regulator converter, fast transient voltage suppressor (TVS) can effectively suppress lightning (LingHEning) and ESD to provide lightning surge protection power of 1500W per line, which can effectively prevent lightning and common ground interference. The RS-232 interface is connected to the computer serial port through a DB9 female connector. Since RS-485 supports two-line and half-duplex, which means that RS-485 has only two lines, it needs to send and receive data. Handshake signals (such as RTS REQUESTTOSEND) usually control the direction of data transmission. The internal circuit of the optically-isolated interface converter can automatically sense the direction of the data flow, and automatically switch the enable control. Can form a RS-485 network conveniently without any handshake signal. This RS-485 enable control is completely transparent, and no software modification is needed for the previous RS-232-based working mode.           It is widely used in industrial automation control systems, card access control systems, unpaid parking garage systems, automatic banking systems, bus toll systems, canteen meal sales systems, company employee attendance management systems, and highway toll station systems.   Performance parameter 1.Interface characteristics: The interface is compatible with RS-232C, RS-485 / RS-422 standards of EIA / TIA;   2.Electrical interface: RS-232C interface, DB9 female connector   3.
