PLCs, Power Supplies & Others

Industrial control systems need precise analog signal processing. The FUJI NU2AXH2-MR delivers reliable data conversion for field devices. This module functions as an Analog I/O expansion unit from FUJI Electric. It integrates seamlessly with FUJI PLC racks and similar controllers.

Technical Specifications & Dimensions

This module supports multiple analog signal types for maximum flexibility. The table below outlines its core technical parameters.

Construction and Interface Layout

This module features a rugged plastic housing with metal shielding. Such a design protects internal circuits from electrical noise. Furthermore, the FUJI NU2AXH2-MR provides a front-accessible terminal block. You will find 24 screw terminals on this interface. Each terminal accepts wire sizes from 0.2 to 1.5 mm². The module also includes a 20-pin ribbon cable connector for backplane communication.

Energy Storage and Signal Processing

Unlike complex analog cards, this module does not use large capacitors for signal smoothing. Instead, it relies on precision resistors and operational amplifiers. Consequently, the unit maintains very low power dissipation during operation. Each input channel includes a dedicated analog-to-digital converter. This architecture enables simultaneous sampling across all eight inputs. The module stores calibration data in non-volatile EEPROM memory. Therefore, you will not lose configuration settings during power cycles.

Installation and Mounting Requirements

Installing the FUJI NU2AXH2-MR takes only a few minutes. The unit snaps directly onto a standard DIN rail. It also requires no additional mounting hardware for secure attachment. Always disconnect the 24V DC power before inserting the module. The unit uses natural convection cooling without any internal fans. This design eliminates fan-related maintenance entirely. The module occupies a single slot in the FUJI PLC rack.

Integration with Control Systems

This I/O module works perfectly with FUJI SPB series PLCs. It provides accurate readings from pressure transmitters and flow meters. Operators can use these analog outputs to drive valve positioners or VFDs. The 12-bit resolution ensures smooth control of industrial processes. Consequently, this model remains a cost-effective choice for system expansions. The FUJI NU2AXH2-MR delivers consistent performance across a 0°C to 55°C temperature range.
