Fuji NC1AX02-PT Resistance Input Module

Precise Temperature Measurement for PT100 Sensors

This resistance input module connects PT100 RTD sensors directly to your PLC system. The Fuji NC1AX02-PT provides two independent channels for temperature measurement. It converts resistance values into digital temperature readings with high accuracy. A built‑in linearization circuit eliminates the need for complex programming. Consequently, this module suits HVAC systems, ovens, and process control applications.

Input Specifications & Temperature Ranges

The Fuji NC1AX02-PT accepts standard 3-wire PT100 resistance temperature detectors. You can select either Celsius or Fahrenheit temperature scaling for each channel. The module automatically compensates for lead wire resistance on each input. A built‑in filter reduces electrical noise from industrial environments. Therefore, this module delivers stable temperature readings even near motors and drives.

Installation & Sensor Wiring

You insert the Fuji NC1AX02-PT into any available slot of your MICREX-SX rack. Connect each PT100 sensor using all three wires for accurate measurement. The module automatically compensates for wire resistance on each channel. Your ladder program reads temperature values directly from dedicated input registers. Consequently, no scaling calculations are required in your PLC code.

Operational Advantages & Precision Measurement

The Fuji NC1AX02-PT eliminates external signal conditioners for temperature sensors. You can measure temperatures as low as -200°C and as high as +850°C. The 0.1°C resolution provides precise control for critical processes. A channel LED indicates active measurement on each input. Therefore, this RTD module delivers reliable temperature monitoring for industrial automation systems.
