Industrial USB to 2-Port RS485 Converter Cable (6KV lightning protection)

View : 168
Type : USB to RS485 Converter
Description :

The basic function of this FC-2105 device is USB to 2-port 6KV lightning protection high-speed RS485 conversion.

Overview

The basic function of this FC-2105 device is USB to 2-port 6KV lightning protection high-speed RS485 conversion. The device is powered by the USB port and does not require an external power supply. It adopts a unique zero-delay automatic transmit/receive conversion technology, plug-and-play compatible with all software, and has transmit/receive enable control. In the standby state without sending data, the output is in a high-impedance state. It supports multi-point communication.

 

This product offers the following features:

Industrial-grade operating temperature (-40 to +85 degrees).

Serial port 6KV three-level lightning protection (10/700us current wave, internal resistance 40Ω).

Built-in gold-plated USB TVS protection (±15kV air discharge and ±8kV contact discharge).

Unique design with 5 LED lights: Power – red light, 2-channel serial port reception – orange light, 2-channel serial port transmission – green light.

Features

The FC-2105 device features a full-speed USB device interface, compatible with USB v2.0.

It comes with an industrial-grade structured USB cable, which has a high-density braided shielding and magnetic ring shielding. The cable also includes a metal wire for tensile strength. Three cable length options are available: 0.5m, 1.5m, and 3m.

The device simulates a standard serial port, allowing for the upgrade of original serial peripheral devices or the addition of additional serial ports through USB.

It is fully compatible with serial port applications on Windows operating systems, requiring no modifications.

The hardware of the device incorporates fully integrated transmit/receive buffers. The 2-channel RS485 interface supports communication baud rates ranging from 1200bps to 10Mbps.

It is suitable for operating systems such as Win98/2K/XP, WIN10/WIN11 32/64-bit systems.

The communication cable is made of shielded twisted pairs of copper wire with a cross-sectional area of at least 0.5mm. The maximum communication distance is 3000 meters (4800bps), 2000 meters (9600bps), and 1000 meters (115.2Kbps).

The minimum number of networked sites is 128, and the maximum number of networked sites is determined by the RS485 input impedance of each site.

It features 5 LED indicator lights: a red light for power, an orange light for 2-channel serial port data reception, and a green light for 2-channel serial port data transmission, providing convenient status monitoring.

It has a gold-plated USB port and is powered by USB. It operates with a working current of less than 30mA. The USB interface protects against electrostatic discharge (ESD) of up to ±15kV (air) and ±8kV (contact). It also offers EFT protection of up to 40A (5/50ns) and lightning protection of up to 5A (8/20us).

The 2-channel RS485 interface is equipped with three-level lightning protection, meeting GB/T17626.5 (IEC61000-4-5) standards. It can handle short-circuit current waves of 10/700μs and has an open-circuit peak output voltage of 6KV. The internal resistance is 40Ω.

The device is designed for a wide temperature range, operating from -40°C to +85°C.
