Description
Product Description
The GE IC693CMM302 is an Ethernet communications coprocessor designed for the Series 90-30 PLC family. This single-slot module enables Series 90-30 PLCs to communicate over Ethernet TCP/IP networks, supporting multiple protocols such as SRTP and Modbus TCP/IP. With integrated diagnostic LEDs and support for up to 31 bus devices, it provides reliable connectivity and monitoring for plant-wide automation systems.
Engineered for legacy GE PLC systems, the IC693CMM302 integrates seamlessly into standard Series 90-30 racks, offering robust backplane isolation and low power consumption (<300 mA at 5 VDC). Its compact design allows flexible slot placement (any slot except the CPU), making it suitable for both new and retrofit installations.
