Product Overview
The GE IC693CPU351DH is a high-performance programmable logic controller (PLC) designed for GE’s Series 90-30 automation platform, delivering reliable control for industrial processes in manufacturing, power generation, and oil and gas sectors. As a single-slot CPU module, the IC693CPU351DH integrates a 25 MHz 80386EX processor and 240 KB user program memory, enabling real-time execution of complex logic, motion control, and data acquisition tasks. It supports up to 7 expansion racks and 2048 I/O points, making it suitable for large-scale automation systems requiring high scalability.
Engineered for rugged environments, the IC693CPU351DH operates within 0°C to 60°C and features a compact design (127mm x 127mm x 76mm) with 0.5 kg weight, ensuring easy integration into space-constrained control cabinets. Its three serial ports (RS-232/485) support protocols like SNP/X, RTU, and ASCII, while the built-in Ethernet interface enables seamless connectivity to HMIs, SCADA systems, and cloud platforms via Modbus TCP and Ethernet/IP 711. The module also includes battery-backed RAM and flash memory for program storage, ensuring data integrity during power outages.
Within the Series 90-30 ecosystem, the IC693CPU351DH interfaces with modules like IC693CHS397 (rack), IC693PWR330 (power supply), and IC695CRU320 (communication module), forming a cohesive control architecture. Its hot-swappable design allows field replacements without system downtime, reducing maintenance costs in 24/7 operations.
