Emerson PACSystems RX3i PLCs and I/O Modules
The Emerson PACSystems RX3i is a high-performance, modular, and scalable control system based on a programmable logic control and expansion modules. This rack-based system is built on PCI standards and provides fast, consistent control between modules. In addition to hundreds of discrete and process I/O points, the PACSystems RX3i features: PACSystems high availability & redundancy, Proficy process systems, integrated PROFINET, easy Machine Edition programming, and HART pass-through. The Emerson PACSystems RX3i offers an easy migration path and replaces discontinued GE Fanuc legacy series, including GE Fanuc 90-30 (9030), GE Fanuc 90-70, GE Fanuc RX7i, GE Fanuc Series 6, GE Fanuc Series 1, and GE Fanuc Series 5.
The GE Fanuc RX3i (now Emerson PACSystems RX3i) is a line of programmable automation controllers (PACs) and control systems designed by GE Fanuc Automation, and later Emerson, for industrial automation tasks. These controllers feature a modular, high-performance architecture with a universal programming environment and offer features like high-speed processors, open communication support, and various I/O modules for diverse applications. The RX3i provides a scalable and flexible solution for various industries and is known for easing the migration from older GE Fanuc PLC systems.
Key Features & Functionality
- Modular Design:
The RX3i system is built on PCI standards, allowing for the addition of various modules such as discrete and analog I/O, communication modules, and power supplies. - Universal Programming Environment:
It uses the Proficy Machine Edition (PME) software, providing a unified environment for programming and configuring the controllers across different hardware platforms. - High Performance:
Equipped with high-speed processors, the RX3i is designed to deliver consistent and fast control in demanding industrial environments. - Migration Path:
The system offers an easy migration path for users of older GE Fanuc systems, such as the GE Fanuc 90-30, simplifying the transition to a more advanced control platform. - Scalability:
The modular nature of the RX3i allows it to be scaled to suit the requirements of various applications, from small to large-scale automated processes. - Cybersecurity:
Modern RX3i controllers incorporate security features like Trusted Platform Modules (TPMs) and digitally signed firmware to protect against cyber threats.
Applications
The PACSystems RX3i is used in a wide range of industries, providing control for processes such as: Manufacturing, Motion control, Process automation, and Machine control.
