Schneider 990NAD21130 Modicon Quantum 6M Drop Cable

990NAD21130 Schneider Electric Modbus Plus Drop Cable

The Schneider Electric 990NAD21130 is a dedicated 6-meter drop cable designed for the Modicon Quantum automation platform. This cable primarily serves as a connection accessory for Modbus Plus networks, enabling reliable communication between field devices and the main controller. Its design includes one male SUB-D 9 connector on the communication module side, while the opposite end remains free for local site tap connections. Consequently, this configuration offers excellent flexibility for various installation scenarios.

Length and Electrical Specifications

The 990NAD21130 provides a generous cable length of 6 meters, which is approximately 19.7 feet. This length offers sufficient reach for most cabinet installations, connecting modules to network taps without excessive slack. The cable features a single male connector designed specifically for the module side, ensuring a secure and proper fit. Meanwhile, the free end allows for direct wiring to your local site tap, accommodating different termination methods. This straightforward design simplifies the cabling process and reduces installation time significantly.

Environmental Operating Parameters

This drop cable performs reliably across a moderate temperature spectrum from 0°C to 60°C. For storage, the 990NAD21130 tolerates a similar range, maintaining its integrity under various warehouse conditions. Furthermore, it supports operating and storage humidity levels up to 80% non-condensing, preventing moisture-related issues in humid environments. The cable also functions correctly at altitudes reaching 1000 meters above sea level, making it suitable for installations in diverse geographical locations.

Compatibility and Platform Support

The Schneider 990NAD21130 offers broad compatibility across multiple Schneider Electric platforms. Beyond the Modicon Quantum series, this cable also works seamlessly with the Modicon Momentum and Modicon Premium automation platforms. Additionally, it integrates with Advantys STB distributed I/O solutions and Lexium 15 servo drives. For specific compatibility, this cable pairs effectively with models like the 140CPU43412U and 140CPU31110 processors, as well as various network tap modules such as the 990NAD23020 and 490NRP25300.
