PLC --Programmable Intelligent Logic Controller converter(AR-1520/AR-1521)

Specifications

AR-1520/AR-1521 Introduction

Most industrial computer systems come with standard RS-232 serial ports. Though RS-232 has widely accepted, it has limited  transmission speed, range, and networking capabilities. The RS- 422 and RS-485 standards overcome these limitations by using differential voltage lines for data and control signals. The AR- 1520/AR1521 converter lets you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. 

It transparently converts RS-232 signals into isolated RS-422 or RS-485 signals. You do not need to change your PC` s hardware or your software. The AR-1520/AR1521 lets you easily build an industrial grade, long distance communication system with standard PC hardware. It extends the communication distance by 4000 ft (1200 m), or increases the maximum number of  connected nodes by 32. It is widely applied to PLC, Modem, printer, POS system and industrial control system.
