GE Fanuc IC697ALG441 16-Channel Analog Input Module | New

Product Overview

The GE Fanuc IC697ALG441 is a high-density, high-precision isolated analog input module designed for seamless system integration within the rugged Series 90-70 programmable logic controller (PLC) architecture. Engineered for demanding real-time data acquisition, this high-performance module features 16 differential analog input channels capable of processing voltage signals across a standard range of -10 to +10 Volts DC. 

Core Technical Advantages

Premium Isolated Differential Signal Inputs

The 16 differential inputs on the IC697ALG441 are completely isolated from the system backplane logic. This electrical barrier prevents field-side ground loops, voltage surges, and transient cross-talk from corrupting central processing calculations, ensuring maximum system uptime and signal integrity.

Jumperless Software Configuration

The module features a streamlined, jumperless architecture that is entirely software-configured via standard MS-DOS or Windows-based programming tools. Eliminating physical DIP switches reduces human installation error and allows parameters to be securely modified, backed up, and replicated electronically.

Scalable Expansion and Minimal Loading

Featuring an input impedance greater than 10 megaohms, the card ensures minimal electrical loading on field instrumentation and sensors. For expansive applications, its robust daisy-chaining capability allows up to 7 modules to link seamlessly with IC697ALG base converters, scaling up to 120 isolated inputs per rack.

Technical Specifications

Installation and Maintenance Guidelines

Mandatory Power Isolation Safety

To protect internal digital processing elements from terminal arcing, system operators must ensure that all rack and external power loops are completely turned off prior to installing, removing, or wiring terminal boards. Never perform hot-swapping procedures on this analog unit.

Field Wiring Optimization

When routing field signal lines into the AWG 22 to 14 terminal blocks, utilize shielded twisted-pair cabling for all ±10V paths. Ground the cable shields at a single point on the chassis enclosure to maximize the inherent high-noise rejection benefits of the module's differential circuitry.

Expansion and Addressing Rules

When daisy-chaining multiple components up to the 7-module threshold, verify correct addressing layouts within the MS-DOS/Windows configuration environment. Ensure that interconnection cables connecting base converters and expansion blocks do not exceed recommended length guidelines to prevent signal drop.

Technical FAQs

Q1: How does the differential input design benefit noisy factory floor applications?

A1: Unlike single-ended modules, the differential input design of the IC697ALG441 measures voltage differences between two distinct lines instead of referencing a common ground. This ignores electrical noise common to both wires, offering excellent noise rejection.

Q2: Are there physical hardware switches or jumpers to adjust on the card?

A2: No. The IC697ALG441 is completely software-configured. All channel allocation, signal tracking, and internal timing adjustments are deployed digitally through official MS-DOS or Windows configuration tools.

Q3: What are the backplane power supply draw specifications for this card?

A3: The analog input module draws a nominal current of 0.4 Amps at a steady +5 Volts DC, maintaining an overall power consumption rating of 2 Watts under full multi-channel operations.
