Product Introduction
When your industrial process demands precise analog signal conversion, the GE IC697ALG230 delivers reliable performance. This base converter module is part of the Series 90-70 PLC platform, originally manufactured by GE Fanuc Automation and now supported by Emerson Automation. It provides eight differential inputs that you can individually configure for voltage or current signals, making it a versatile choice for high-level analog input systems.
Technical Specifications Breakdown
The IC697ALG230 offers key specifications that drive its functionality. It features eight analog inputs with a 16-bit analog output resolution, ensuring accurate signal conversion. The voltage input range spans -10 to +10 volts, while the current input range covers 4 to 20 milliamps. The module supports differential wiring, which enhances resistance to electromagnetic interference. Its update rate is fast, ranging from 2.4 ms to 2.8 ms. Calibration is factory set at 10 volts +/- 2 mV, with voltage accuracy of +/- 0.01% of full scale and +/- 0.02% of value. Linearity is ±.02% of full scale over the entire negative to positive range.
Industry Applications
In manufacturing environments where precise measurement is critical, the IC697ALG230 excels. For example, in a chemical processing plant, you can configure each channel to monitor temperature or pressure transmitters using 4-20 mA signals. The differential wiring configuration minimizes noise, ensuring reliable data acquisition. Additionally, in a power generation facility, you can use the module to handle voltage signals from sensors, maintaining accuracy over long cable runs.
Installation & Setup Guidance
To install the IC697ALG230, first ensure the PLC backplane is powered off. Insert the module into a Series 90-70 rack slot, securing it firmly. Connect user devices to the removable 40-terminal connector block on the front face. Use a jackscrew driver to remove the block for wiring. Configure each input individually via the MS-DOS Windows configuration software, selecting voltage or current mode as needed. For expander modules, attach them through the expansion port, supporting up to seven expanders for a maximum of 120 inputs.
Maintenance & Reliability
Regular inspection of the IC697ALG230 ensures long-term reliability. Check for loose connections on the terminal block and verify that the module’s door insert labels remain legible. The module includes opto-isolation to protect against backplane noise. Since it is discontinued, verify availability with SpareTechPLC before ordering. Routine checks of the update rate and calibration can prevent drift, maintaining accuracy within factory specifications.
Compatibility & Integration
The IC697ALG230 integrates seamlessly with the Series 90-70 PLC system. It works with expander modules IC697ALG440 (voltage) and IC697ALG441 (current) to increase channel count. The module uses a serial communication port to control expanders via the base converter processor. It also supports CPU alarm interrupts and fault reporting on a per-channel basis, enhancing system diagnostics.
Selection Guide & Purchasing Advice
Before purchasing the IC697ALG230, confirm your system’s compatibility with Series 90-70 racks. Since this product is discontinued, contact SpareTechPLC to check current stock and find suitable replacements. Ensure you have the required expander modules if you need more than eight inputs. SpareTechPLC offers reliable sourcing for this legacy module, helping you maintain existing systems without costly upgrades.
