USB to RS485 Converter (6KV lightning protection)

View : 933
Type : USB to RS485 Converter
Description :

The device is designed to provide USB to RS485 conversion with a function of 6KV lightning protection.

Overview

The device is designed to provide USB to RS485 conversion with a function of 6KV lightning protection. It is powered by a USB port, eliminating the need for an external power supply. It features a unique and instantaneous automatic transmission and reception conversion technology, ensuring plug-and-play compatibility with all software applications. It incorporates a transmit/receive enable control, where the output remains in a high-impedance state during standby mode without data transmission, and supports multi-point communication.

 

Distinguishing itself from other similar low-cost products available in the market, the device offers the following notable features:

Industrial-grade operating temperature range (-40℃ ~ +85℃)

RS485 serial port with 6KV three-level lightning protection (10/700us current waveform, internal resistance of 40Ω)

Gold USB interface with built-in TVS protection (±15kV air discharge and ±8kV contact discharge)

3 LED indicators: Power (red), Serial Receive (orange), Serial Transmit (green)

Features

The device provides a full-speed USB device interface, compatible with USB v2.0.

It emulates a standard serial port, allowing for the upgrade of existing peripheral devices or the addition of extra serial ports via USB.

It ensures complete compatibility with serial port applications on Windows operating systems, without the need for any modifications.

It incorporates hardware with fully integrated transmit and receive buffers, supporting communication baud rates ranging from 50bps to 2Mbps.

It is compatible with operating systems such as Win98/2K/XP, WIN10/WIN11 (32/64-bit), Linux, MAC OS-9/X, and Android.

It utilizes shielded twisted pair cables with a minimum cross-sectional area of 0.5mm copper, allowing for communication distances of up to 3000 meters (4800bps), 2000 meters (9600bps), or 1000 meters (115.2Kbps).

It supports a minimum of 128 network nodes, with the maximum number of nodes determined by the RS485 input impedance of each station.

It features three LED indicators: Power (red), Serial Data Receive (orange), and Serial Data Transmit (green), providing convenient status monitoring.

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

The RS485 interface is equipped with three-level lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) standard. It can withstand a short-circuit current waveform of 10/700μs and an open-circuit peak output voltage of 6KV, with an internal resistance of 40Ω (instantaneous protection power >900,000W).

The device also includes a 5V power output terminal (with 0.5A PTC protection) that activates to protect the device when operating above 0.7A.

Operating temperature range of -40℃ to +85℃.

It has passed 100% burn-in testing.
