GE 44A723621-001 IC600CM548A

Product Overview

The GE Fanuc 44A723621-001 IC600CM548A is associated with an 8K CMOS logic memory module for the GE Series Six PLC family. This memory hardware is designed for Model 600 and Model 6000 control systems, where it provides storage for the user control program. Public product records identify the corresponding IC600CM548 family as an 8K CMOS logic memory module.

For plants still operating legacy Series Six equipment, this type of memory module can be an important maintenance component. It allows technicians to preserve the original PLC architecture instead of immediately replacing the entire control system.

Main Product Details

• Manufacturer: GE Fanuc
• PLC family: Series Six
• Associated model: IC600CM548A
• Internal identification: 44A723621-001
• Memory type: CMOS logic memory
• Logic memory capacity: 8K
• Compatible platform: Model 600 / Model 6000
• Memory technology: CMOS-RAM
• Status indicators: BATTERY and PARITY LEDs

The Series Six compatibility documentation identifies IC600CM548 as an 8K logic-memory option, while other memory modules in the same family provide different capacities.

Memory and Program Storage

Unlike an I/O module, this component is focused on memory rather than direct field-device control. The logic memory stores the user program used by the PLC, including ladder-diagram logic and related programming information.

The CMOS-RAM design requires battery-backed retention when system power is removed. The available technical information identifies a lithium-manganese dioxide battery arrangement and a battery-status monitoring function.

Status Monitoring

Two indicators provide useful maintenance information. The BATTERY LED is associated with the condition of the memory backup battery, while the PARITY LED provides information related to memory parity status. These indicators can help technicians identify potential memory-related issues during troubleshooting.

For older PLC installations, checking the battery condition should be part of routine maintenance. A backup-memory failure can create serious problems if the stored control program is not properly preserved.

Typical Applications

This memory module is suitable for maintenance and replacement requirements involving legacy GE Series Six systems. Typical environments may include:

• Manufacturing equipment
• Production machinery
• Material handling systems
• Industrial process control
• Factory automation
• Legacy PLC control cabinets

Its primary value is in supporting existing systems where the original PLC hardware remains operational and compatible spare parts are required.

Replacement Considerations

Before ordering a replacement, compare the complete catalog number, hardware markings, and existing PLC configuration. The IC600CM548 family includes related identification formats, while the A suffix identifies a particular version.

Our company supplies industrial automation spare parts for PLC maintenance and equipment repair. Customers can provide the complete part number and product photographs when requesting availability or compatibility confirmation.
