Description

Product Overview

The ​​GE IC695LCU003​​ is a high-performance CMOS expansion memory module developed by GE (now under Emerson Automation) for the ​​90-70 series PLC systems​​, designed to extend the logic and data storage capabilities of programmable controllers in industrial automation. This module integrates seamlessly with co-processor modules (e.g., ​​IC697PCM711​​) and CPUs (e.g., ​​IC697CPU771/772​​), acting as a sub-board installed in the same slot to supplement the base memory of the host module . Equipped with a ​​12 MHz 80C186 microprocessor​​ and ​​32 KB of integrated memory​​, the ​​IC695LCU003​​ supports real-time control of machinery, material handling systems, and complex processes by enabling rapid data access and execution of large-scale control programs. It eliminates the need for physical jumpers or DIP switches, relying instead on software configuration via MS-DOS or Windows-based tools over Ethernet TCP/IP or SNP ports. With built-in validation checks during power-up and runtime, the module ensures configuration integrity and triggers alarms for deviations, enhancing system reliability in demanding environments like manufacturing plants and energy facilities .

Key Features and Advantages

​​Scalable Memory Expansion​​: The ​​GE IC695LCU003​​ offers four memory configurations (64–512 KB), allowing flexible adaptation to project complexity without hardware modifications. This scalability optimizes resource allocation for large I/O systems, supporting up to 8K analog and discrete I/O points .

​​Real-Time Diagnostics and Validation​​: During operation, the module continuously verifies programmed configurations against actual hardware states. Deviations trigger immediate alarms, reducing troubleshooting time by 30% in critical processes like assembly line synchronization or turbine control .

​​Industrial-Grade Reliability​​: Designed for 24/7 operation in harsh conditions, the module operates within ​​0°C–60°C​​ and includes battery-backed RAM (via ​​IC694ACC302​​ or ​​IC690RBT001​​ batteries) to preserve data during power outages. This ensures uninterrupted control in environments like offshore platforms or automotive plants .

​​Plug-and-Play Integration​​: Native compatibility with ​​90-70 series CPUs​​ and VME C.1 backplane communication simplifies retrofitting into legacy systems. Firmware updates via serial ports (RS-232/RS-485) minimize downtime during upgrades .

Application Areas

  • ​​Manufacturing Automation​​: Extends memory for robotic arm sequencing and conveyor control in automotive production lines, handling high I/O counts with millisecond response precision .
  • ​​Energy Infrastructure​​: Supports data logging and real-time monitoring in power plants, ensuring stability for turbine control systems and emergency shutdown protocols .
  • ​​Water Treatment Systems​​: Manages chemical dosing and pump control algorithms in high-humidity environments, leveraging moisture-resistant components for continuous operation .
  • ​​Logistics Automation​​: Coordinates automated storage/retrieval systems (AS/RS) and palletizing robots, optimizing warehouse throughput via enhanced program storage .
