Description

GE IC693CPU350

Technical Specifications

  • Processor Type: 80386EX.
  • Processor Speed: 25 MegaHertz (MHz).
  • User Program Memory: 32K Bytes (RAM and Flash, not configurable).
  • Discrete I/O Capacity: Up to 2,048 discrete input points (%I) and 2,048 discrete output points (%Q).
  • Analog I/O Capacity: 2,048 words for analog inputs (%AI) and 512 words for analog outputs (%AQ).
  • Timers/Counters: Over 2,000 available.
  • Power Requirement: 670 milliamps from a +5 VDC supply.

Functional Features

  • High-Speed Processing: Executes logic at a typical scan rate of 0.22 milliseconds per 1K of boolean logic.
  • Flexible Communications: Features a built-in serial port supporting SNP/SNP-X slave protocols, with options for Ethernet, FIP, Profibus, GBC, and GCM via expansion modules.
  • Advanced Memory: Supports discrete global memory, internal coils, temporary output coils, and extensive register memory (%R).
  • Battery-Backed Clock: Maintains accurate timekeeping and data retention during power loss.
  • Floating Point Math: Supports firmware-based floating-point math (in firmware releases 9.0 and later).

Application Scenarios
Extensively deployed in manufacturing automation, material handling, water treatment facilities, and general industrial process control requiring reliable, mid-range PLC performance.

Performance Parameters

  • Operating Temperature: 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) ambient.
  • System Expansion: Supports up to 8 total baseplates per system (1 CPU baseplate + 7 expansion/remote racks).
  • Interrupts: Supports periodic subroutine features for time-critical tasks.

Material Composition
Housed in a durable, industrial-grade plastic enclosure with a precision metal backplane connector and robust internal PCB assembly.

Structural Characteristics
Single-slot form factor designed for standard Series 90-30 baseplates. Features front-panel status LEDs (ON/OFF), a PS PORT connector, and configuration interfaces.

Working Principle
The CPU continuously scans the user program, reads the status of input modules, executes logic based on the programmed instructions, and updates the output modules accordingly, all while managing background communication tasks.

Installation Requirements
Must be installed in the left-most slot (CPU slot) of a Series 90-30 baseplate. Requires a compatible +5 VDC power supply capable of delivering at least 670mA to the backplane.

Usage Precautions
Always observe electrostatic discharge (ESD) precautions when handling. Ensure the system is powered down before inserting or removing the module. Verify that the installed memory battery is functional to prevent data loss.
