Fuji NP1BS-08 Base Board

Rack Architecture and Physical Configuration

The Fuji NP1BS-08 provides an 8-slot base board for the NP1 Series programmable controller platform. It supports CPU modules, power supplies, and I/O modules in a single integrated assembly. This base measures 12.0 cm in height, 28.5 cm in width, and 11.5 cm in depth. It weighs approximately 1.2 kg, offering substantial structural integrity for industrial mounting applications.

This unit features a passive backplane that distributes power and data signals to all installed modules. The backplane accommodates up to 8 modules arranged in a single row for straightforward system configuration. Engineers can populate slots with any combination of NP1 Series compatible components. This flexibility allows users to build custom control systems tailored to specific application requirements.

Interface Connections and Slot Architecture

The NP1BS-08 includes eight individual slot connectors that provide both power and communication pathways. Each slot features keying mechanisms that prevent incorrect module insertion during installation. The base board includes four mounting holes on each side for secure panel attachment. A DIN rail mounting option also accommodates applications requiring quick removal and repositioning.

The backplane design supports hot insertion of select modules for maintenance without system shutdown. This capability reduces downtime when replacing faulty components in critical applications. The base also provides grounding terminals for connecting chassis ground to protective earth systems.

Power Distribution and Energy Management

This base board distributes 5 VDC and 24 VDC power from the power supply module to all occupied slots. It incorporates power filtering components that reduce electrical noise on the backplane. The passive design includes overcurrent protection circuitry that isolates faults to individual slots. This isolation prevents a single module failure from affecting the entire system.

Technical Specifications

System Integration and Compatibility

The NP1BS-08 accepts all NP1 Series CPUs, including the NP1PS-74D and NP1PU-048EZM models. It supports power supplies such as the NP1PS-74D and other NP1 Series power modules for various power requirements. Users can combine this base with input modules like NP1X3206-W and output modules such as NP1Y32U09P1 for complete system configurations. This base board serves as the foundation for scalable NP1 Series control systems.
