FUJI NC1AX04-08 PLC Module | 8 Analog Inputs

This PLC module provides analog input capabilities for Fuji MICREX-SX series systems. The FUJI NC1AX04-08 accepts eight independent analog channels from field transmitters. Each channel supports voltage or current inputs with high-resolution conversion. Consequently, automation engineers can monitor pressure, flow, and temperature signals accurately.

Technical Specifications of the PLC Module

The FUJI NC1AX04-08 measures 113.6 mm in width and 90 mm in height. Its depth reaches 76 mm for standard MICREX-SX rack mounting. The module weighs approximately 0.24 kg including all analog and isolation circuitry. A single front panel LED array shows power status and channel activity. The front side features a removable screw terminal block for field wiring connections. This design stores minimal energy in small filtering capacitors only. Therefore, the module contains no batteries or large energy storage elements.

Functional Features and Signal Conditioning

The FUJI NC1AX04-08 allows you to select voltage or current inputs using DIP switches. You can mix input types across the eight channels for maximum flexibility. The module provides 500V AC isolation between field circuits and the backplane. Integrated filtering removes 50Hz and 60Hz noise from industrial environments. Consequently, the module delivers stable, accurate readings even near variable frequency drives.

Installation and System Integration

You must install this analog input module into a standard MICREX-SX rack slot. The FUJI NC1AX04-08 connects to the CPU through the backplane automatically. A removable terminal block accepts field wiring from 14 to 22 AWG. The module requires no external power supply for loop-powered transmitters. Always verify input signal ranges before connecting field devices to the channel terminals.

Maintenance and Operational Benefits

Because the FUJI NC1AX04-08 stores no battery-backed data, it needs no periodic battery changes. Technicians can replace the module without losing any configuration settings. The transparent terminal cover prevents accidental contact with live field wires. Consequently, this analog input module offers safe and simple maintenance for industrial control systems.
