Desktop 1 Port Serial RS485-422-232 All in One Serial to Fiber Converter FCP-041620

This fiber optic transceiver provides one channel of three-in-one serial port (RS232/422/485) transmission over fiber optic cable. Each RS232/422/485 interface is simultaneously available, facilitating on-site service activation. This product overcomes the limitations of traditional serial interface communication distance and speed, while also solving problems related to electromagnetic interference, ground loop interference, and lightning damage. It significantly improves the reliability, security, and confidentiality of data communication and can be widely used in various industrial control, process control, and traffic control applications. It is particularly suitable for banks, power companies, and departments and systems with special requirements regarding electromagnetic interference environments.

● Based on proprietary integrated circuit technology;

● Provides one channel of three-in-one RS485/422/232 serial port transmission over fiber optic cable, with each RS232/422/485 port simultaneously available for convenient on-site service activation;

● Features automatic serial port signal baud rate detection, automatically detecting and controlling the RS-485 data flow without the need for handshake signals;

● RS232/485/422 channels can transmit asynchronous serial data with adaptive baud rates from 0-115.2bps;

● Serial port lightning protection meets IEC61000-4-5 (10/700μS) differential mode: 6KV, impedance (40Ω); common mode: 6KV, impedance (40Ω) standards;

● Power supply supports strong lightning protection: protection against lightning strikes, resistance to induced high voltage, and surge protection; fanless high-efficiency heat dissipation reduces repair time;

● When using DC power (external power supply), it supports DC 9-12V;

● When using AC 220V power (built-in power supply): supports AC 85-265V wide-range input;

● When using DC -48V power (built-in power supply): supports DC 36-72V wide-range input.
