Product Details

overview

NLK232-4H is an industrial grade card rail serial port isolation line converter that supports bidirectional transparent conversion between RS485/232 master station and multiple RS232 slave stations, improving the RS232 bus structure,. The product provides 1 main station RS485/232 and 4 slave station RS232 serial ports, supporting DC5-30V power input. It adopts a standard DIN card rail installation method to meet the needs of various industrial bus sites. Provide RS232 star connection method, changing the single structure of the original bus and bringing great convenience to network layout. The hardware adopts a fanless, low-power, wide temperature, and wide voltage design, with carefully selected industrial grade components that support a wide operating temperature range of -40 ℃ to+85 ℃, suitable for various harsh on-site environments. The product can be widely used in indoor and outdoor systems such as attendance, access control, gimbal control, food sales, and parking lots
