PRODUCT INFORMATION
Product Overview
The General Electric IC693CPU352 is a single-slot Processor Module for Series 90-30 programmable logic controller systems. It features an 80386EX processor running at 25 MHz with a built-in math co-processor for floating-point calculations. The typical scan rate executes at 0.22 milliseconds per 1K step of Boolean logic. The unit mounts directly onto the CPU baseplate and connects to expansion baseplates across the system rack.
This controller supports up to 240 Kbytes of user memory with firmware release 9.0 or higher. Earlier firmware versions allocate 80 Kbytes of user memory. The module draws 910 milliamps from the 5 VDC bus and dissipates 4.55 Watts of heat. Front indicators display status for SNP communication as well as serial Port 1 and Port 2 activity.
