Emerson PAC8000 Remote I/O The Control Solution for Process Industries

Emerson PAC8000 Remote I/O The Control Solution for Process Industries

Product Overview

Core positioning: PAC8000 Remote I/O is a fully modular remote I/O solution developed by Emerson for the process industry. It adopts a carrier based architecture and supports applications in general scenarios and hazardous areas (including intrinsic safety signals). It can be seamlessly integrated with PACSystems RX3i and RSTi EP controllers through PROFINET/Modbus TCP, suitable for process control requirements in harsh environments.

Core design concept: With "high reliability, wide environment adaptation, and convenient operation and maintenance" as the core, it supports live operation and hot plugging in hazardous areas, provides comprehensive diagnostic functions, and reduces downtime and maintenance costs.
