☆ work: This product is imported from the United States original industrial chip program; industrial iron shell: high temperature, high pressure, heat fast, explosion-proof, anti-lightning and other industrial communications product features; to adapt to various industrial harsh environments. Asynchronous half-duplex (RS-485/232) opto-isolated enhanced (isolation voltage 2.5KVrms / 500VDC insulation), both ends with dedicated DC / DC module isolation protection, dual port 232 / RS485 1500W per line to provide lightning protection Chung, isolation function; at the same time each line to provide +/- 15KV ESD protection and to prevent a total of interference, four signals at the same time independent transmission does not interfere with the real pure industrial products.
The ZP-1304 is an internal design of the dual-core, endless (uninterrupted) design, designed to solve the complex electromagnetic field environment RS-485 large system requirements and design of the RS485 bus segmentation hub (HUB). The product supports the transmission rate up to 115.2KBPS, in order to ensure the safe and reliable data communication, RS-485 interface using optical isolation technology to prevent lightning surge into the converter and equipment. In the RS485 operating mode, the discriminant circuit can automatically sense the direction of the data flow, and automatically switch to enable the control circuit, easy to solve the RS485 transceiver conversion delay problem. RS485 interface transmission distance greater than 1200 meters, stable performance.
Scope of application:
It is especially suitable for railway, military, financial and securities, customs, civil aviation, maritime transportation, industrial automation, electric power, water conservancy, security, access control system, time and attendance system, access control system, selling system, POS system, building automation system, self-service banking system Room monitoring, power monitoring and other broadband data network and require high reliability data transmission or the formation of IP data transmission network of industrial communications.
