FUJI NP1BS-06 Base Board | 6 Slots

This base board provides a mounting backplane for Fuji MICREX-SX PLC modules. The FUJI NP1BS-06 accepts up to six I/O and CPU modules in a single assembly. A multilayer PCB distributes power and communication signals to all inserted modules. Consequently, automation engineers can build compact control systems using standardized base boards.

Technical Specifications of the Base Board

The FUJI NP1BS-06 measures 210 mm in width and 130 mm in height. Its depth reaches 30 mm for standard panel or DIN rail mounting. The board weighs approximately 0.75 kg including the backplane and mounting hardware. A single ground lug provides a common connection point for system grounding. The rear side features a 24-pin expansion connector for multi-rack systems. This design stores no energy whatsoever. Therefore, the base board contains no capacitors, batteries, or any other storage elements.

Functional Features and System Integration

The FUJI NP1BS-06 routes all power and communication signals to each slot evenly. You can mix CPU, I/O, and specialty modules within the same base board. The backplane provides automatic addressing based on physical slot position. A keying bar prevents incorrect module insertion into the wrong slot. Consequently, this base board simplifies cabinet assembly and reduces wiring errors.

Installation and Configuration

You must mount this base board on a flat panel or 35mm DIN rail. The FUJI NP1BS-06 requires a 24V DC power supply for field circuits. A 24-pin ribbon cable links multiple base boards for expanded I/O capacity. The board includes numbered slot labels for easy module identification. Always verify backplane integrity before inserting any modules into the chassis.

Maintenance and Operational Benefits

Because the FUJI NP1BS-06 stores no energy, it requires no discharge time before handling. Technicians can replace individual modules without removing the base board from the cabinet. The open frame design allows natural convection cooling for all inserted modules. Consequently, this base board provides reliable service with minimal maintenance requirements.
