Fuji NP2L-OE1 MICREX-SX Bus Interface Module

High-Speed Data Exchange Between Racks

This bus interface module connects multiple MICREX-SX racks into a single system. The Fuji NP2L-OE1 handles high-speed data transfer between the main CPU and expansion racks. It extends the backplane bus to remote locations up to 100 meters away. A built‑in status LED indicates normal communication and error conditions. Consequently, this module enables large distributed automation systems without performance degradation.

Bus Specifications & Expansion Capabilities

The Fuji NP2L-OE1 uses a dedicated SX bus protocol for deterministic data exchange. You can connect up to 8 expansion racks to a single master CPU using this module. The bus automatically synchronizes all I/O data during each CPU scan cycle. A shielded twisted-pair cable provides noise immunity for industrial environments. Therefore, this module suits large factories with equipment spread across multiple rooms.

Installation & System Integration

You insert the Fuji NP2L-OE1 into the dedicated bus slot of your MICREX-SX expansion rack. Connect the shielded bus cable to the 9-pin D-sub connector on the front panel. A second identical module resides in the main CPU rack for complete system integration. The bus automatically synchronizes after power-up without configuration. Your CPU then accesses remote I/O as if they were local modules.

Operational Advantages & Distributed Architecture

The Fuji NP2L-OE1 eliminates the distance limitation of standard backplane buses. You can place I/O racks near field devices to reduce wiring costs significantly. The high-speed 10 Mbit/s transfer ensures no bottleneck in system performance. A LINK LED confirms active communication between all connected racks. Therefore, this bus module provides flexible expansion for large-scale automation systems.
