2 Port Serial to Fiber Converter | (RS-485/422/232 All Available)

View : 1,490
Type : Serial to Fiber Converter
Description :

This device adopts an industrial-grade design with large-scale FPGA technology, providing 2 serial ports that support RS232/422/485 interfaces simultaneously on each port.

Overview

This device adopts an industrial-grade design with large-scale FPGA technology, providing 2 serial ports that support RS232/422/485 interfaces simultaneously on each port. It is the best choice for connecting remote terminal units (RTUs) to hosts or distributed data acquisition systems (SCADA) controllers, with a high performance-to-price ratio. The effective communication distance can reach up to 0-120 kilometers, and the communication speed of the serial port can reach up to 0-256KBPS.

Features

The device provides 2 serial ports, with each port simultaneously providing RS232/422/485 serial interfaces (interface type can be set via DIP switches), making it easy to activate on-site services.

It can automatically detect and control RS-485 data flow without using handshake signals to control the data flow direction.

It can automatically detect the baud rate of the serial port signal.

The serial channel can transmit asynchronous serial port data with adaptive baud rates ranging from 0-256Kbps.

The serial port interface is protected against lightning strikes according to the IEC61000-4-5 (10/700μS) standard: differential mode (6KV impedance at 2Ω); common mode (6KV impedance at 2Ω).

● When dual DC power supply:

   It can be powered by DC9-55V or AC7-50V wide-range power supply. The power supply has the function of polarity automatic detection, and there is no need to distinguish between positive and negative poles during installation;

  It supports internal isolation, redundant dual power supply inputs, and reverse polarity protection.

● When AC power supply:

   It supports AC~85-265V AC, or DC110-300V DC wide-range input.

DIN 35mm rail mount or wall-mounted.
