Product Overview

The Fuji NR2JAX-04IMRDT serves as a compact programmable controller for industrial automation tasks. This unit provides robust logic control for small to medium-sized applications. It handles discrete and analog I/O with reliable execution performance. The system integrates seamlessly into Fuji Electric NR series control architectures.

Technical Specifications

Physical Dimensions and Mounting

This programmable controller measures 250 mm in width, 40 mm in height, and 160 mm in depth. The unit weighs approximately 0.85 kg. It mounts onto a DIN rail or directly onto a panel plate. The front panel includes LED indicators for power, run, fault, and I/O status. These LEDs provide immediate visual feedback on system operation.

Processor Architecture and Memory

The NR2JAX-04IMRDT employs a 16-bit microcontroller for efficient control processing. It stores user programs in 16 KB of combined RAM and EPROM memory. The data memory capacity reaches 4 KB for storing process variables. The CPU executes logic instructions at a speed of 0.5 ms per 1K operations. It includes 64 timers and 64 counters for timing and counting tasks.

I/O Capabilities and Expansion

This controller comes with 16 digital inputs and 16 digital outputs built into the unit. It also includes 4 analog inputs and 2 analog outputs for process monitoring. The digital inputs accept 24 VDC signals from switches and sensors. The analog I/O handles 4–20 mA or 1–5 VDC signal types. The unit supports expansion through the NR series backplane for additional modules.

Communication and Connectivity

The built-in RS-232 serial port connects to programming terminals or operator interfaces. This port supports data exchange with HMIs, printers, and host computers. The controller also includes a programming port for software uploads and downloads. It supports both polled and interrupt-driven communication methods for flexible integration.

Installation and System Integration

You can install this controller on a DIN rail inside the control cabinet. Connect the external 24 VDC power supply to the designated terminals. Wire the digital and analog I/O to the front-access terminal blocks. Configure the system parameters using the programming software. Always verify the I/O wiring before applying power to the system.

Environmental Compliance

This controller carries CE marking for industrial use. It also complies with RoHS environmental directives. The unit suits standard control cabinet installations with IP20 protection.
