GE IC693CMM302 Series 90-30 Serial Communication Module
Product Overview
The GE IC693CMM302 is a serial communication module in GE’s Series 90-30 PLC system, designed to connect industrial controllers to devices using serial protocols. It lets PLCs like the IC693CPU374 communicate with HMIs, printers, barcode scanners, and other serial-enabled equipment, making it essential for linking automation systems in factories, power plants, and water treatment facilities.
As a key communication tool, the IC693CMM302 supports RS-232, RS-422, and RS-485 protocols, covering most common serial standards. This flexibility means it can work with both new and older devices, avoiding the need to replace legacy equipment. The module fits into Series 90-30 racks, working seamlessly with power supplies like the IC693PWR330 and I/O modules such as the IC693MDL740K.
Built for tough industrial use, the IC693CMM302 operates in temperatures from 0°C to 60°C and resists dust and vibrations. Its compact size allows easy installation in crowded control cabinets, while LED indicators on the front show power and communication status, simplifying troubleshooting. Whether used to send production data to a printer or receive sensor readings, the IC693CMM302 ensures reliable data flow in critical operations.

Main features and advantages
Supports multiple serial protocols: The IC693CMM302 works with RS-232, RS-422, and RS-485, so it can connect to almost any serial device—from old printers to new barcode scanners. This flexibility means factories don’t need different modules for different equipment.
Easy to integrate: The module fits directly into Series 90-30 racks like the IC693CHS397, with no need for extra adapters. It uses a standard DB9 port, so technicians can use off-the-shelf cables, making setup quick.
Tough for industrial use: Built to handle temperatures from 0°C to 60°C, dust, and vibrations, the IC693CMM302 works reliably on factory floors. It doesn’t need special protection, even in harsh spots like near welding machines or in hot production areas.
Works with new and old systems: The IC693CMM302 is fully compatible with all Series 90-30 modules, from controllers to I/O cards. This means users can add it to existing systems without replacing other parts, saving money.
Clear status indicators: LED lights on the front show if the module is powered, connected, or having communication issues. This makes it easy to spot problems—like a loose cable—without opening the control cabinet.
Installation and maintenance
Pre-installation preparations: Make sure the Series 90-30 rack (such as the IC693CHS397) is powered off. Check that there’s an open slot for the IC693CMM302. Gather a DB9 cable (matching the device you’re connecting) and a screwdriver. Verify that the PLC’s firmware is up to date to ensure compatibility.
Maintenance suggestions: Check the IC693CMM302 monthly by looking at the LED indicators—steady lights mean it’s working. Wipe dust off the front with a dry cloth to keep the LEDs visible. Every three months, check the DB9 cable connection to make sure it’s tight. If communication stops, try swapping the cable first; if that doesn’t work, use the LEDs to see if the module has power or a connection issue.
Application fields
The GE IC693CMM302 is widely used in industries where serial communication is needed:
In automotive factories, it connects PLCs to HMIs on the assembly line, letting operators see real-time data like robot status. It also sends production logs to printers, helping track how many parts are made each shift.
In water treatment plants, it links PLCs to flow meters and level sensors that use serial protocols. The IC693CMM302 ensures the PLC gets accurate data, so operators can adjust pumps and valves to keep water flow steady.
In small manufacturing shops, it connects older equipment—like manual lathes with serial outputs—to the main PLC. This lets the shop monitor all machines from one system, even if some are older models.
In food processing facilities, it sends temperature data from freezers (via serial sensors) to the PLC. If the temperature goes out of range, the PLC can trigger an alert, preventing food spoilage.
