Description
GE IC693CPU311 5-slot embedded CPU backplane
Product Dimensions：
The GE Fanuc Series 90-30 IC693CPU311 is a foundational, base-level CPU module designed for small-scale industrial automation. While it is an older model in the Series 90-30 family, its reliability has made it a staple in legacy systems.
## Product Overview
The IC693CPU311 is a single-slot CPU that plugs into the first slot of a 90-30 baseplate. It is an “embedded” CPU, meaning the processor is built directly into the backplane, providing a cost-effective solution for simple control logic without the need for high-speed processing or massive memory.
## Technical Specifications
| Feature | Specification |
| Processor Speed | 10 MHz |
| Processor Type | 80188 |
| Typical Scan Rate | 1.5 milliseconds per 1K Boolean logic |
| User Memory | 6 KB (Fixed) |
| I/O Discrete Points | 512 Inputs / 512 Outputs |
| Analog I/O Channels | 128 Inputs / 64 Outputs |
| Communication | Support for SNP/SNP-X protocols via power supply port |
| Internal Power Usage | 430 mA from +5VDC bus |
## Key Advantages
-
Reliability: Known for an incredibly high Mean Time Between Failures (MTBF), making it ideal for “set it and forget it” applications.
-
Cost-Efficiency: As an entry-level model, it provides the essential functions of a PLC without the price tag of high-performance controllers.
-
Compact Design: Fits perfectly into small enclosures where space is at a premium.
-
Ease of Programming: Compatible with standard GE programming software (Proficy Machine Edition or Logicmaster 90).
## Important Considerations & Precautions
-
Memory Limits: With only 6 KB of memory, it is not suitable for complex algorithms, extensive data logging, or large-scale floating-point math.
-
Battery Maintenance: Ensure the battery in the power supply is functional. If the battery dies while the power is off, the CPU will lose its volatile memory (the program).
-
No Expansion: This specific CPU does not support “Remote I/O” or “Expansion Racks” as robustly as the higher-end CPU350+ models. It is best used as a standalone controller.
-
Firmware: Being a legacy product, ensure your programming software version supports the firmware version on the hardware.
## Typical Applications
The IC693CPU311 is widely used in industries requiring straightforward sequence control, such as:
-
Packaging Machinery: Simple conveyor control, sorting, and wrapping.
-
Water Treatment: Small-scale pump station control and level monitoring.
-
HVAC Systems: Management of air handling units and boiler controls.
-
Material Handling: Basic lift station and palletizer operations.
