Product Description
DB9 Male RS232 to RS485 RS422 Serial Converter
PCM-KW-474 is an active RS232 to RS485 RS422 converter for connecting equipment that uses different serial interface standards. The converter takes an RS232 interface as the input and provides RS485 or RS422 differential communication at the terminal side. This allows existing RS232 equipment to interface with RS485 or RS422 devices without changing the original host interface.
The DB9 male connection and terminal block wiring make the converter straightforward to integrate into equipment and control systems. As an RS232 to RS485 converter and RS232 to RS422 converter, PCM-KW-474 is intended for serial interface conversion where different communication interfaces need to be connected within the same system.
Applications :
Remote Monitoring
Support RS232 to RS485 or RS422 connections in distributed monitoring and control equipment.
Sensor Interfaces
Provide serial interface conversion between RS232 equipment and compatible industrial sensors.
PLC Communication
Connect compatible RS232 equipment with PLC and control systems using RS485 or RS422 interfaces.
Long Distance Communication
Convert RS232 signals to differential RS485 or RS422 signals for serial communication over longer cable runs.
Industrial Automation
Interface computers, controllers, terminals, sensors, and other serial devices within industrial automation systems.
Key Features :
Status LED
An integrated Active LED provides a visual indication of converter operating status.
RS422 Output
Dedicated Rx and Tx differential connections provide full duplex RS422 signal transmission.
DB9 Male RS232 Input
A D Sub 9 Pin DB9 male connector provides the RS232 interface for compatible serial equipment.
RS485 Output
