8-port Intelligent RS-232 Converters

Introduction

The PCL-8441/PCL-8442 8-port RS-422 converters are designed to work with PCL-844 intelligent 8-port RS-232 card. They converts the RS-232 signal to isolated RS-422 for protection, longer distance and better noise immunity. The PCL-8441 is a non-isolated converter whereas the PCL-8442 is an isolated converter.

Applications

• Data acquisition and control with RS-422 based devices
• PLC monitoring and control
• Instrument controller, distributed control system
• Modem server, database server, POS controller
• Multi-user system

Features

• RS-422 output for industrial and laboratory control
• 500 VDC isolation protection
• Up to 4000 feet (1.2 Km) data transmission
• LED indicators on each port indicate data flow
