Invensys Triconex 4200 - Remote Extender Module

Invensys 4200 Remote Extender Module Overview

The Invensys 4200 Remote Extender Module (RXM) enables remote I/O placement up to 12 kilometers from the main chassis. This advanced system utilizes sets of three identical modules that function as both repeaters and bus extenders while delivering complete electrical isolation. A single primary RXM set can efficiently support three separate remote locations through reliable connections to remote RXM sets.

Key Features and Capabilities

• Extends operational range to 7.5 miles (12 kilometers) from primary control chassis
