GE IC693CPU374

Product Introduction

The IC693CPU374 is a high-performance single-slot CPU module in the GE Fanuc Series 90-30 PLC system, serving as the core for advanced industrial automation with real-time processing and communication. It is powered by a 133 MHz AMD SC520 (586-class) processor, delivering a 0.15 ms per 1K Boolean logic scan rate for rapid control execution. It features 240 KB of user memory (Flash + RAM), dual embedded 10/100 Mbps Ethernet ports with auto-sensing, and an RS-485 serial port (via power supply) supporting SNP/SNPX protocols. The module supports up to 8 baseplates (1 CPU + 7 expansion/remote), works with VersaPro 2.03+ and Proficy Machine Edition 2.60+ software, and preserves data via battery backup, making it ideal for medium to large-scale automation requiring high-speed communication and complex logic processing.
