DTECH Industrial RS232 to RS485 Serial Converter, 3-Channel RS485 Expansion Hub with 600W Surge Protection, TX RX Indicator Lights, Power Adapter & Terminal Block, Industrial Grade Serial Communicatio

This DTECH industrial-grade RS232 to RS485 serial converter is a professional signal conversion and expansion solution designed for industrial automation, PLC communication, instrument monitoring and long-distance serial data transmission.

It converts a single RS232 serial signal into three independent RS485 channels, allowing one host device to connect multiple RS485 slave devices simultaneously, greatly expanding your serial communication capacity.

Engineered for harsh industrial working conditions, the converter integrates 600W surge protection circuitry to effectively resist instantaneous voltage surges and lightning interference, preventing hardware burnout caused by unstable power or line static. Visible TX and RX LED lights display real-time sending and receiving data signals, so users can quickly judge whether communication links work normally without extra testing tools.

The device comes with a dedicated power adapter and standard screw terminal block. Wiring via terminals is firm and convenient, suitable for fixed industrial wiring layouts. It supports long-distance signal transmission of RS485 standard, with strong anti-interference performance to guarantee stable data transmission in noisy factory environments.

Widely compatible with industrial controllers, sensors, access control systems, and all equipment equipped with RS232 and RS485 serial ports, it is an essential serial communication accessory for automation engineering projects.
