IC697ALG230 Functional Description

The IC697ALG230 is a key component in the Series 90-70 Programmable Logic Controller (PLC) platform, previously manufactured by GE Fanuc Automation and now under Emerson Automation. This base converter module is designed to manage analog input signals, offering eight differential channels that can be configured for voltage or current inputs, including 4-20 mA current output and -10VDC to +10VDC voltage output signals. Each channel features 16-bit resolution, ensuring high accuracy in analog data conversion. The IC697ALG230 Analog Input Base Conversion Module also supports the addition of expansion modules, such as the IC697ALG440 (voltage) and IC697ALG441 (current) expander modules, which allow users to expand the system to handle up to 16 channels per module, greatly enhancing its flexibility and capacity.

A standout feature of the IC697ALG230 Analog Input Base Conversion Module is its integrated 14-bit Analog-to-Digital Converter (ADC), which converts analog input signals into digital form. The module is equipped with individual low-pass filters on each channel to improve signal quality and reduce noise. Additionally, an opto-isolation circuit ensures that the IC697ALG230 Analog Input Base Conversion Module is electrically isolated from the PLC backplane, helping to protect the system from electromagnetic interference (EMI).

The IC697ALG230 Analog Input Base Conversion Module uses differential wiring for signal input, which enhances resistance to EMI and is ideal for environments where precise measurement is crucial. The module’s user-friendly design includes a removable 40-terminal connector block for easy connection and maintenance. Furthermore, the IC697ALG230 Analog Input Base Conversion Module is compatible with up to seven expansion modules, enabling a system to support up to 120 input channels. For configuration, users can take advantage of GE's MS-DOS Windows software, which allows easy programming of each channel's input parameters.

In summary, the IC697ALG230 Analog Input Base Conversion Module is a versatile and robust analog input module that can be expanded to meet the needs of complex automation systems, offering flexibility, precision, and ease of integration with additional modules.
