4210 Invensys Triconex Model RXM | 12km Remote

Invensys 4210 Remote Extender Module Overview

The Invensys 4210 Remote Extender Module (RXM) enables remote placement of I/O modules several kilometers from the main chassis. This system uses sets of three identical modules that act as repeaters and bus extenders while providing complete ground loop isolation. A primary RXM set can support up to three separate remote locations through connection to remote RXM sets.

Key Features and Capabilities

• Extends I/O operations up to 7.5 miles (12 kilometers) from primary chassis
• Provides complete ground loop isolation between sites
• Uses fiber-optic cabling for maximum noise immunity
• Supports communication rate of 375 kilobits per second
• Offers superior protection against electro-static and electro-magnetic interference
• Enables connection to three remote sites from one primary RXM set
