The Schneider Electric 990NAD21110 is a Modbus Plus (MB+) station cable designed for industrial automation networks. It serves as a critical connectivity component for linking Modbus Plus devices, such as remote I/O stations, PLCs, and field equipment, within Schneid’s Modicon and Quantum automation platforms. This cable enables reliable data transmission in distributed control systems (DCS) and process automation environments.

Key Features

1. Modbus Plus Compatibility: Optimized for Modbus Plus networks, a high-speed, token-passing protocol used in industrial automation for real-time data exchange.
2. Multi-Platform Support: Compatible with Schneid’s Modicon Momentum, Quantum, Premium, and Advantys STB distributed I/O systems.
3. Robust Construction: Built to withstand harsh industrial environments, with shielding to minimize electromagnetic interference (EMI).
4. Plug-and-Play Design: Simplifies installation and integration into existing Modbus Plus networks.

Applications

The 990NAD21110 is widely used in:

• Modicon Quantum/Momentum Systems: Connecting remote I/O stations to central PLCs.
• Distributed Control Systems (DCS): Linking field devices (sensors, actuators) to control nodes.
• Process Automation: Ensuring reliable communication in manufacturing, energy, and utility applications.
