FUJI NP1BS-08S – 8-Slot PLC Base Board | NP1B Series Expansion Backplane
Engineering Background
The FUJI NP1BS-08S is a dedicated base board (backplane) designed for the FUJI NP1B series programmable logic controller platform. As the structural and electrical backbone of the NP1B control rack, it provides 8 module slots for CPU, I/O, communication, and special function modules, enabling scalable and modular machine automation architectures across discrete manufacturing, process control, and motion applications.
Product Positioning
Targeted at OEM machine builders, system integrators, and MRO procurement engineers who require a verified, drop-in replacement or expansion backplane for existing FUJI NP1B installations. The NP1BS-08S eliminates the need for full rack replacement and supports phased capacity expansion without rewiring.

Proven Application Environments
- Discrete manufacturing: assembly lines, conveyor control, robotic cell integration
- Process automation: chemical dosing, HVAC control, water treatment
- Motion control: multi-axis servo coordination via NP1B motion modules
- MRO replacement: direct swap for failed or aging NP1BS-08S backplanes in existing NP1B racks
- Capacity expansion: adding I/O or communication modules to existing NP1B control panels
Engineering Advantages
- 8-slot capacity — accommodates full NP1B module complement in a single rack, reducing panel footprint
- Modular architecture — mix CPU, digital I/O, analog I/O, and fieldbus communication modules freely across slots
- Robust backplane bus — low-impedance internal bus ensures signal integrity at high I/O scan rates
- Tool-free module insertion — NP1B locking mechanism enables rapid module swap without rack removal
- Wide thermal tolerance — rated for 0–55°C continuous operation in industrial enclosures
- OEM-grade reliability — manufactured to FUJI Electric’s industrial quality standards with full traceability
System Architecture & Signal Flow
The NP1BS-08S serves as the physical and electrical interconnect layer of the NP1B control system. The CPU module (installed in the designated CPU slot) communicates with all peripheral modules via the backplane bus. I/O modules receive field signals from sensors and actuators; the CPU processes logic and issues control outputs at each scan cycle. Communication modules (e.g., PROFIBUS, Ethernet/IP, CC-Link) bridge the NP1B rack to supervisory SCADA or DCS networks. The 8-slot layout supports up to 7 peripheral modules alongside the CPU, or can be configured as a pure I/O expansion rack when paired with a remote I/O adapter.

Technical FAQ
Q: Is the NP1BS-08S compatible with all NP1B series CPU modules?
A: Yes. The NP1BS-08S is the standard 8-slot base board for the NP1B platform and is compatible with all NP1B CPU variants. Confirm your specific CPU model with our technical team if uncertain.
Q: Can I use the NP1BS-08S as a remote I/O expansion rack?
A: Yes, when paired with a compatible FUJI remote I/O master/slave adapter, the NP1BS-08S can function as a distributed I/O rack on supported fieldbus networks.
Q: What is the maximum number of I/O points supported per rack?
A: This depends on the I/O module types installed. With 7 peripheral slots available (1 reserved for CPU), maximum I/O density is determined by the highest-density NP1B I/O modules selected. Contact us for a slot-by-slot configuration review.
Q: Do you provide warranty on this unit?
A: Yes. All units carry a 90-day functional warranty covering manufacturing defects and transit damage. Extended warranty options are available for volume orders.
Q: Can you supply other NP1B series components?
A: Yes. Konmask.com maintains inventory of NP1B CPU modules, I/O modules, power supplies, and communication modules. Submit your full BOM for a consolidated quote.
