GE IC693CMM301 Modular Control Module

We’ve received multiple inquiries recently about communication modules for legacy GE systems. The IC693CMM301 is particularly popular among clients upgrading older PACSystems setups while maintaining compatibility with existing infrastructure.

One of our recent clients in the oil & gas sector used this module to bridge legacy Modbus RTU devices with modern Ethernet-based control systems. The dual-port design allows simultaneous connection to different network architectures, which proved crucial during their phased migration process.

Common applications include:

• Connecting legacy GE 90-30 PLCs to Ethernet networks
• Multi-protocol communication gateways in hybrid systems
• Remote I/O interface for distributed control cabinets

Works with these systems:

• GE PACSystems RX3i
• GE 90-30 series PLCs
• Profibus DP slaves (via appropriate configuration)

Our inventory includes both new sealed units and tested refurbished modules. All come with 12-month warranty covering both parts and performance. We’ve had several clients report this module outperforming newer alternatives in extreme temperature environments – one chemical plant in Xinjiang had units running continuously for 18 months without issues at -20°C ambient temperatures.
