PRODUCT INFORMATION
Product Overview
The General Electric IC693CPU311 is an embedded CPU baseplate designed for the Series 90-30 control platform. This assembly features five module slots alongside an integrated 80188 microprocessor operating at 10 MHz. The system provides 6 KB of user program memory and supports 512 words of reference memory. An onboard memory socket accepts optional non-volatile EPROM or EEPROM expansion modules. Typical program execution operates at 18 milliseconds per 1K of Boolean logic contacts.
This baseplate provides dedicated slots for five input or output modules and one power supply module. Backplane logic operation requires 410 milliamps of current load from a 5 VDC rated power supply. Serial communication is hosted through a port located on the system power supply module. The hardware supports 160 discrete inputs, 160 discrete outputs, 64 analog input words, and 32 analog output words. Operating ambient temperatures range from 32 to 140 degrees Fahrenheit, or 0 to 60 degrees Celsius.
