Fuji NB2U56T-11 PLC Module | MICREX-NB Compact

All-in-One Controller for Small Automation Tasks

This compact PLC unit integrates CPU, power supply, and I/O in a single housing. The Fuji NB2U56T-11 provides 56 digital I/O points for small machine control applications. It accepts 24V DC input signals from sensors and push buttons. Transistor outputs drive solenoids, relays, and indicator lights directly. Consequently, this module eliminates the need for a multi-rack system.

I/O Configuration & Memory Specifications

The Fuji NB2U56T-11 features a built-in programming port for easy code uploads. You can expand I/O using additional NB series modules up to 256 total points. A lithium battery preserves the user program during power interruptions. The unit operates reliably in temperatures from 0°C to 55°C. Therefore, this controller suits conveyor systems, packaging machines, and small assembly stations.

Installation & System Integration

You mount the Fuji NB2U56T-11 on a standard DIN rail inside your control panel. Connect 24V DC power to the dedicated power terminals on the top. Wire your sensors to the 32 input terminals on the upper section. Wire your actuators to the 24 output terminals on the lower section. For larger systems, connect expansion modules using the ribbon cable.

Operational Advantages & Compact Design

The Fuji NB2U56T-11 saves significant panel space compared to modular PLCs. You can program this unit using standard Fuji NB series software tools. Each input and output channel includes an LED for instant status verification. The transistor outputs switch silently without relay noise or contact wear. Therefore, this compact PLC provides a cost-effective solution for original equipment manufacturers.
