The Schneider Electric 990NAD21930 is a specialized drop cable designed for Modbus Plus network connections. This cable serves as a critical link between communication modules and junction boxes. It features a generous length of 6 metres (19.7 feet). Therefore, it provides ample reach for flexible equipment layouts. One end terminates with a straight SUB-D 9 connector for direct attachment to communication modules. Meanwhile, the opposite end presents flying leads for straightforward junction box wiring. Consequently, the 990NAD21930 simplifies network installation and maintenance. Additionally, this cable is compatible with the Modicon Momentum platform and Altivar 71/61 drives. For instance, you can use it in factory automation, process control, or distributed I/O applications.
The Schneider Electric 990NAD21930 drop cable features a robust construction suitable for industrial environments. The cable length measures precisely 6 metres (19.7 ft). This length allows for convenient routing between devices without excessive slack. The electrical connection consists of a SUB-D 9 straight connector on the communication module side. Furthermore, flying leads are provided on the junction box side for flexible termination options. The localisation on the device is on the right side, ensuring consistent orientation during installation. The net weight is only 0.465 kg (1.025 lb). Therefore, the cable imposes minimal strain on connected ports and connectors.
The 990NAD21930 operates reliably within specified environmental parameters. The ambient temperature range for operation is 0°C to 40°C. This range covers typical indoor industrial and commercial settings. The operating humidity reaches up to 80% (non-condensing). Similarly, the storage humidity also tolerates 80% non-condensing conditions. Therefore, the cable maintains its performance in moderately humid environments. Additionally, the maximum operating altitude is 1000 metres above sea level without derating. This capability ensures consistent signal integrity at higher elevations. For applications above 1000 metres, please consult Schneider Electric for derating guidelines.
The Schneider Electric 990NAD21930 offers broad compatibility within the Schneider Electric ecosystem. It is specifically designed for the Modicon Momentum automation platform. Moreover, it works seamlessly with Altivar 71 and Altivar 61 variable speed drives. The cable is also compatible with the 990NAD23000 accessory, enabling extended network configurations. This cable is intended for use in connecting junction boxes to Modbus Plus networks. Therefore, it is ideal for distributed control systems, remote I/O installations, and drive networks. The SUB-D 9 connector plugs directly into compatible communication modules. Meanwhile, the flying leads terminate at the junction box for secure and reliable connections.
Installing the 990NAD21930 is straightforward for qualified technicians. The SUB-D 9 connector provides a secure, locking connection to the communication module. This prevents accidental disconnection due to vibration or movement. The flying leads on the other end allow for custom wiring to terminal blocks. Consequently, this design accommodates various junction box configurations. The lightweight design (0.465 kg) simplifies handling and routing. Additionally, the cable's 6-metre length offers flexibility in panel layout design. For best results, avoid sharp bends and excessive tension during installation. Also, ensure the connectors are properly tightened to maintain signal integrity.
Schneider Electric manufactures the 990NAD21930 to high quality standards. The cable construction ensures reliable data transmission in industrial environments. Its design resists typical environmental stresses such as temperature variation and humidity. Furthermore, the connector materials provide durable, long-lasting performance. This cable carries the CE mark, confirming compliance with relevant European standards. The product is part of Schneider Electric's comprehensive range of connection accessories. Therefore, you can trust its performance in critical automation networks.
