GE IC697ALG441 Voltage Expander Module 16 Inputs

IC697ALG441 GE Fanuc Analog Input Expander -10/+10V

Product Introduction

The IC697ALG441 is a voltage expander module manufactured by GE Fanuc for the Series 90-70 programmable logic controller platform. This analog input expander provides 16 differential inputs with a -10 to +10 Volt input range, making it suitable for a wide variety of industrial sensing applications. Moreover, the module acts as an interface between the PLC processor and field input devices such as transducers, sensors, and actuators. One of its key strengths lies in its expandability—users can daisy-chain up to seven IC697ALG441 modules to achieve a total of 120 analog inputs. Additionally, the module is factory-calibrated at 10V ±2 mV with a maximum error of ±0.03% of full value, ensuring reliable and precise data acquisition. Configuration is straightforward and requires no jumpers or DIP switches, which simplifies setup and reduces installation time significantly.

Technical Specifications

The IC697ALG441 delivers accurate analog input expansion across diverse industrial applications. Below are the key technical parameters:

• Number of Inputs: 16 differential inputs

• Input Voltage Range: -10 to +10 Volts

• Input Impedance: >10 megohms

• Conversion Rate: 2 ms

• Calibration: Factory-set at 10V ±2 mV

• Maximum Error: ±0.03% of full value, ±0.02% of value

• Power Requirement: 0.4 A (2 W) at +5 V DC

• Isolation: All inputs isolated from backplane

• Field Power: Not required

• Terminal Board Wire Size: AWG 22 to 14

• Weight: Approximately 4 lbs (1.82 kg)

Furthermore, the differential input design does not depend on ground reference or power supply commons. Both input lines run directly to the signal source, providing excellent noise rejection for reliable measurements in electrically noisy environments. In addition, the isolation between inputs and the backplane enhances system protection and signal integrity.

Expansion Capability and System Integration

The IC697ALG441 offers remarkable scalability through its daisy-chain expansion feature. Specifically, users can connect up to seven expander modules in series, increasing the total analog input count from 16 to 120. This capability proves particularly valuable for large-scale applications that require extensive analog monitoring without consuming excessive backplane slots.

Meanwhile, the module is specifically designed to work with GE Fanuc IC697ALG base converter modules and other expansion modules. By maximizing input utilization, the IC697ALG441 helps reduce initial material and inventory costs while improving overall system efficiency. Additionally, all inputs are isolated from the backplane of the base converter module, which enhances signal integrity and protects the PLC system from field-side electrical disturbances. Therefore, system integrators can confidently deploy this expander in complex automation architectures.

Configuration and Installation

Configuring the IC697ALG441 is remarkably simple. First, the module does not require jumpers or DIP switches for setup. Instead, all configuration is performed using the MS-DOS or Windows-based programming software (compatible with Windows 95 and Windows NT). This software-driven approach eliminates hardware adjustments and consequently reduces the risk of configuration errors.

For proper installation, follow these guidelines:

1. Power Down – Disconnect power from the PLC rack before installing or removing terminal boards.

2. Slot Selection – Choose an available slot in the Series 90-70 chassis.

3. Insertion – Slide the module along the card guides until it seats firmly into the backplane connector.

4. Wiring – Connect field devices to the terminal board using AWG 22 to 14 wires. Additionally, connect both input lines to the signal source for differential operation.

5. Configuration – Use the programming software to assign I/O references and set up input parameters.

6. Power Up – Restore power and verify normal operation through the PLC logic.

Remember that the field side of the IC697ALG441 does not require an external power supply, which simplifies wiring and reduces component costs. Moreover, the differential input structure ensures that ground loops and common-mode noise are effectively minimized, resulting in cleaner data acquisition.
