Overview
The GE Fanuc IC693CPU311 is a compact 5-slot embedded CPU baseplate designed for the Series 90-30 Programmable Logic Controller platform. Originally manufactured by GE Fanuc (now part of Emerson Automation), this unit integrates the processor directly into the baseplate backplane, eliminating a separate CPU module and providing a space-efficient solution for entry-level industrial automation applications with moderate I/O requirements.
Key Features
- 5-slot baseplate with integrated 80188 processor (non-removable, soldered to backplane)
- 6 KB user program memory (1 KB registry memory) with support for optional EPROM/EEPROM expansion
- Supports up to 160 discrete inputs, 160 discrete outputs, 64 analog input words, and 32 analog output words
- One built-in SNP slave and SNP-X slave serial port (hosted by power supply module)
- Boolean execution time of 18 ms per 1K logic
- 170 embedded timer/counter instructions and shift register support
- Super-capacitor backed memory retention on power loss
