USB to RS232 RS485 Serial Converter Port Module with Push-Button (Terminal Block)

Brand:
DTECH
Item NO.:
IOT5091(FT)

Product Details

A USB to RS232/485 serial port module with push-button (terminal block) connections is a type of industrial-grade converter that allows a computer's USB port to communicate with serial devices using either the RS232 or RS485 standard via secure screw terminals.

Key Features and Functionality Connectivity: These modules typically feature a USB Type-A or Type-B connector for the host computer and a multi-pin screw terminal block for the RS232 and/or RS485 connections. The terminal blocks provide a secure, industrial connection that is less prone to accidental disconnection than standard serial connectors.

Switching: Communication mode (RS232 or RS485) is often selected using on-board physical switches, jumpers, or DIP switches, eliminating the need for complex software configuration.

Chipset: Reputable modules often use original chips like the FT232,known for their stability and broad operating system compatibility (Windows, macOS, Linux, Android).

Protection: Designed for industrial use, many modules include protection features such as self-recovery fuses, TVS (Transient Voltage Suppressor) diodes, surge protection, and ESD (Electrostatic Discharge) protection. Some advanced versions also offer optical isolation to further protect connected equipment.

Indicators: On-board LED indicators for power (PWR) and data transmission/reception (TXD/RXD) allow users to monitor the operational status and data flow visually. Power: These adapters are typically powered via the host USB port, meaning no external power supply is usually required.

Common Applications These modules are widely used by engineers and technicians to interface modern computers with a variety of industrial equipment, including: PLCs (Programmable Logic Controllers) Barcode scanners Serial sensors and embedded systems LED signage and control panels Automation and industrial control equipment
