Fuji NP1AXH6G-PT Standard I/O Module

Analog Input Architecture and Signal Processing

The Fuji NP1AXH6G-PT functions as a 6-channel analog input module for the NP1 Series programmable controller platform. It accepts platinum resistance thermometer (Pt100) signals for precise temperature measurement applications. This module converts resistance values into digital data for processing by the CPU. It supports 3-wire Pt100 connections that compensate for lead wire resistance automatically.

Each input channel features individual isolation to prevent interference between adjacent circuits. The module provides 16-bit resolution for accurate temperature readings across the full measurement range. Consequently, engineers can deploy this unit in HVAC, process control, and thermal monitoring applications requiring high precision.

Physical Specifications and Mounting

The NP1AXH6G-PT measures 12.0 cm in height, 7.5 cm in width, and 11.5 cm in depth. It weighs approximately 0.28 kg, allowing for straightforward installation in standard Fuji NP1 Series racks. This module occupies a single slot on the baseplate and connects directly to the backplane bus. The front panel features LED indicators for module status and channel activity monitoring. These visual indicators provide immediate feedback during system startup and troubleshooting.

A removable terminal block accommodates all field wiring connections for the six input channels. This terminal block accepts wire sizes ranging from 0.2 to 1.5 mm² (24 to 16 AWG). The module also includes shield connection terminals for minimizing electrical noise interference.

Power Consumption and Energy Storage

This analog input module draws 180 mA from the backplane at 5 VDC for internal logic operation. It incorporates energy storage capacitors that maintain configuration data during brief power interruptions. These capacitors provide approximately 15 milliseconds of hold-up time to preserve calibration parameters. The module also retains configuration settings in non-volatile memory without requiring battery backup.

Technical Specifications

System Integration and Temperature Measurement

The NP1AXH6G-PT integrates seamlessly with Fuji NP1 Series CPUs, power supplies, and digital I/O modules. It provides scaled temperature data directly to the CPU for process control algorithms. Users can configure input ranges and scaling parameters using Fuji standard programming software. This module enables accurate temperature monitoring for industrial ovens, HVAC systems, and thermal processing equipment.
