GE IC693BEM331 Series 90-30 Ethernet Communication Module
Product Overview
The GE IC693BEM331 is a key communication module in GE’s Series 90-30 PLC system, designed to connect industrial controllers to Ethernet networks. It lets PLCs like the IC693CPU374 share data with computers, HMIs, and other devices, making it easier to monitor and control machines in factories, power plants, and water treatment facilities.
As a critical link in automation systems, the IC693BEM331 supports standard Ethernet protocols, allowing smooth communication at speeds up to 100 Mbps. This means real-time data—like machine status or production counts—can move quickly between the PLC and control rooms. It works with both new and older Series 90-30 setups, so factories don’t have to replace their entire system to add network capabilities.
The IC693BEM331 is built to handle tough industrial conditions. It works in temperatures from 0°C to 60°C and can stand up to dust and vibrations, which is important in busy factories. With its compact size, it fits easily into existing control cabinets, making upgrades simple. Whether used in automotive assembly lines or food processing plants, this module helps keep operations running smoothly by ensuring reliable data flow.

Main features and advantages
easy network integration: The IC693BEM331 connects Series 90-30 PLCs to Ethernet without complicated setup. It uses standard cables and ports, so technicians familiar with basic networking can install it quickly. This is a big plus for factories that want to add remote monitoring without hiring specialists.
fast and reliable data transfer: With 10/100 Mbps speeds, the IC693BEM331 ensures data like production counts or error alerts moves quickly. This is crucial for time-sensitive tasks, such as stopping a conveyor if a part is misaligned. It also reduces delays in updating HMI screens, so operators always see the latest machine status.
tough enough for industrial use: Built to handle dust, vibrations, and temperatures from 0°C to 60°C, the IC693BEM331 works reliably in factories where conditions are harsh. It doesn’t need special enclosures, saving space and money.
works with new and old systems: The IC693BEM331 fits perfectly with existing Series 90-30 components like the IC693CPU374 and IC693PWR330. This means factories don’t have to replace their entire PLC system to get Ethernet capabilities, which cuts costs.
simple troubleshooting: LED lights on the front show if the module is powered, connected to the network, or having issues. This makes it easy to spot problems—like a loose cable—without opening the control cabinet.
Application fields
The GE IC693BEM331 is widely used in industries where connecting PLCs to networks is key:
In automotive factories, it links assembly line PLCs to central computers, so managers can track how many cars are built each hour. If a robot stops working, the IC693BEM331 sends an alert immediately, helping fix the issue faster.
In water treatment plants, it connects PLCs that control pumps and valves to SCADA systems. Operators can check water flow rates from a distance, and the module ensures the data is always up-to-date, preventing overflows or equipment damage.
In food processing facilities, it helps monitor temperature controls on ovens or freezers. If the temperature goes out of range, the IC693BEM331 sends a signal to the HMI, letting workers adjust settings before food quality is affected.
In small to medium factories, it’s used to connect multiple PLCs in different areas—like packaging and labeling lines—so all data goes to one central system. This makes it easier to coordinate production and spot bottlenecks.
Installation and maintenance
Pre-installation preparations: Make sure the Series 90-30 rack (like the IC693CHS391) is powered off. Check that the rack has an open slot for the IC693BEM331. Gather Ethernet cables (CAT5 or better) and a screwdriver. Verify the PLC’s firmware is up to date—older versions might need an update to work with the module.
Maintenance suggestions: Every month, check the IC693BEM331’s LEDs to ensure power and network lights are on. Wipe dust off the front with a dry cloth to keep the LEDs visible. Every three months, check the Ethernet cable connections to make sure they’re tight. If the module stops communicating, try swapping the cable first—it’s often the simplest fix. If problems continue, the LED lights can help narrow down issues, like a failed network port.
