USB TO RS485 CONVERTER

OVERVIEW

USB TO RS485 CONVERTER

The USB-RS485 is a fully automatic plug-and-play USB module that connects to your PC via the Universal Serial Bus (USB) port and provides robust USB to RS-485 protocol conversion with automatic RS-485 flow control. This converter provides two way serial communications signal conversion between the RS485 to and from a personal computer USB port using virtual serial COM port.Using the USB-RS485 module , one can connect upto 32 RS-485 devices simultaneously to a single USB port. Typically it is used for multi-drop communication.

 The USB-RS485 module provides an easy to use RS485 interface by means of a Virtual Com Port on the users system. The module is completely self powered from the USB bus. Simply use the standard COM-port interface to automatically connect  RS-485 over USB.

REGULATED POWER SUPPLY

OVERVIEW

INTRODUCTION

The regulated power supply accepts unregulated inputs from 9V to 15V AC or DC and gives regulated output of 3.3V, 5V and 12V suitable for projects which needs precise voltage to work. The input can come from step down transformer. Since board has Diode Bridge input polarity does not matter. All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.

FEATURES

•          Input Voltage AC/DC 0-12.
•          Output Voltages +3.3V +5V, +12V.
•          Inputs and output connected to terminal blocks.
•          Maximum Load 1 Amps.
•         LED Indicator.
•          All outputs to Screw Terminal.

• APPLICATIONS

·         Mobile Phone power adaptors

·         Regulated power supplies in appliances

·         Various amplifiers and oscillators
