The Schneider NUL 200 fills unused slots inside Modicon 200 series I/O racks. Engineers specify this blank when empty positions must maintain airflow and backplane integrity. Consequently, the unit keeps cabinet layouts clean and protects exposed connectors from dust.

Physical Dimensions and Weight Data

Cabinet space often limits how technicians arrange modules along the backplane. Therefore, this blank keeps a slim profile that matches standard module footprints. It weighs roughly 0.2 kg and measures 120 mm in height. Additionally, its width spans 40 mm with a depth of 100 mm.

Interfaces and Construction Details

Reliable rack protection depends on a secure fit at every vacant slot position. The unit provides a moulded housing that clips directly onto rack rails. Furthermore, the front face carries no electrical contacts or terminals. The design allows tool-free installation and removal during cabinet maintenance.

Component Count and Material Data

Material selection shapes both durability and long-term appearance. This blank uses a single-piece thermoplastic housing without internal circuitry. Moreover, the surface resists scratching during routine panel work. The material meets flame-retardant standards for industrial enclosures.

Key Technical Specifications

Rack Protection and Compliance

Proper slot coverage directly influences overall cabinet airflow. The blank maintains consistent ventilation paths across populated racks. Meanwhile, the moulded housing blocks dust from reaching backplane connectors. These features support dependable operation in harsh plant environments.

Industrial sites also demand strict safety certifications before deployment. The blank complies with IEC and UL standards for industrial control equipment. In addition, it meets CE requirements for electromagnetic compatibility. These credentials ensure safe integration with Modicon 200 hardware.
