Triconex 4211 Remote Expansion Module (RXM) – Extend Your I/O Systems Over Long Distances

The Triconex 4211 Remote Expansion Module (RXM) allows you to extend your I/O modules up to 12 kilometers (7.5 miles) away from the main chassis. Designed for robust industrial applications, this module and its accompanying chassis enable seamless communication and reliable performance in remote locations. The 4211 RXM set includes three identical modules that act as repeaters and extenders for the Tricon I/O bus, ensuring efficient data transmission over long distances.

Key Features and Benefits of the Triconex 4211 RXM

The Triconex 4211 RXM offers critical advantages for remote I/O configurations in industrial automation systems.

1. Extended Range: The 4211 RXM allows remote I/O modules to be located up to 12 kilometers (7.5 miles) away from the primary chassis. This long-range capability is crucial for applications requiring distributed I/O setups across large facilities or remote sites.
2. Ground Loop Isolation: The RXM provides effective ground loop isolation, ensuring reliable communication in environments prone to electrical noise and interference. This feature enhances system stability, particularly in challenging industrial settings.
3. Fiber-Optic Communication: The 4211 RXM supports fiber-optic cables with a communication rate of 375 kilobits per second. Fiber-optic transmission provides maximum immunity to electrostatic and electromagnetic interference, ensuring secure and uninterrupted data transfer.
4. Modular Setup: A primary RXM set can support up to three remote locations. Each location connects to three remote RXM sets housed in a separate chassis, enabling flexible expansion and scalability of the system.
5. Dual-Channel Data Transmission: The 4211 RXM utilizes uni-directional cabling for efficient data transmission. Each remote location requires six cables (three channels, two cables per channel), ensuring reliable communication between the primary and remote RXM modules.
6. Optical Modem Support: The 4211 RXM can be configured with optical modems, enabling point-to-point fiber-optic cabling. This setup increases system reliability and performance by ensuring stable connections in remote installations.
