Technical Specifications and Physical Characteristics

Understanding the exact specifications of the GE IC693CPU360 ensures proper integration into your Series 90-30 control system. This processor features the advanced 80386EX microprocessor for efficient program execution.

Processing Performance and Scan Rates

The GE IC693CPU360 delivers exceptional processing speed for complex control applications. Its 25 MHz clock ensures rapid execution of user logic and program functions.

• Processor Speed: The 80386EX microprocessor operates at 25 MHz clock speed. This provides ample processing power for most industrial control applications.

• Scan Rate: It achieves a typical scan rate of 0.22 milliseconds per 1K of logic. This applies specifically to Boolean contact logic in your application program.

• Logic Execution: The CPU handles both Boolean and functional block instructions efficiently. Consequently, it suits applications mixing discrete and continuous control.

• Interrupt Response: Hardware interrupts receive priority processing for time-critical events. This ensures rapid reaction to external process conditions.

• Backplane Speed: The module communicates with I/O at high speed through the backplane. Therefore, overall system throughput remains excellent for demanding applications.

Memory Architecture and Storage Capabilities

The GE IC693CPU360 provides substantial memory capacity for user programs and configuration data. Its dual memory technology ensures both performance and data retention.

• User Memory: The CPU offers 240K Bytes of total user memory capacity. This stores ladder logic, function blocks, and configuration parameters.

• Memory Type: It utilizes both RAM and Flash memory technologies for different purposes. RAM provides fast execution while Flash retains programs during power loss.

• RAM Function: Volatile RAM stores the active program during normal CPU operation. A lithium battery maintains this memory when you remove system power.

• Flash Storage: Non-volatile Flash memory holds a backup copy of your application program. Therefore, the CPU can reload RAM automatically after power restoration.

• Memory Protection: Built-in write protection prevents accidental modification of stored programs. This safeguards your intellectual property and prevents unauthorized changes.

Power Requirements and Electrical Specifications

The GE IC693CPU360 draws moderate power from the backplane for reliable operation. Its efficient design minimizes heat generation within the control cabinet.

• Voltage Input: The module requires +5 Volts DC from the backplane power supply. This standard voltage suits all Series 90-30 racks and power supplies.

• Current Consumption: It draws 670 milliamps from the +5 V DC supply during operation. Therefore, verify adequate power supply capacity before installation.

• Power Dissipation: The CPU dissipates approximately 3.35 Watts maximum during full operation. This low value reduces cooling requirements within the enclosure.

• Inrush Current: Initial power-on draws slightly higher current for capacitor charging. The power supply must accommodate this momentary surge.

• Isolation: The module provides optical isolation from field-side circuits. This protects the CPU from voltage transients on I/O wiring.

Communication Interface and Connectivity

The GE IC693CPU360 utilizes a unique communication approach within the Series 90-30 family. It relies on the power supply module for its primary serial connection.

• Serial Communication: The CPU uses the RS485 port located on the power supply module. Consequently, it has no embedded communication port on the processor itself.

• Protocol Support: The RS485 interface supports SNP (Series Ninety Protocol) for programming. This enables connection to programming software and operator interfaces.

• Network Connectivity: For Ethernet communications, you must add a separate Ethernet module. The IC693CPU360 itself includes no embedded Ethernet ports.

• Programming Access: Connect a programming terminal to the power supply RS485 port. This provides full access to CPU memory and logic for development.

• Multi-Drop Capability: The RS485 interface supports multi-drop networks with multiple CPUs. Therefore, you can connect several processors to a single programming station.

Environmental Specifications and Operating Conditions

The GE IC693CPU360 operates reliably across a wide range of environmental conditions. Its robust design suits demanding industrial automation applications.

• Operating Temperature: The module functions from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). This range accommodates most indoor control room environments.

• Storage Temperature: It withstands storage from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). This tolerance ensures survival during shipping and warehouse storage.

• Humidity Rating: The CPU operates at 5% to 95% relative humidity without condensation. Conformal coating protects components from moisture damage.

• Vibration Resistance: It withstands 2G vibration from 10 to 500 Hz during operation. This ensures reliable performance in moderate vibration environments.

• Shock Resistance: The module tolerates 15G shock during operation and 30G during storage. This protects against damage during installation and maintenance.

System Integration and Applications

Integrating the GE IC693CPU360 into your Series 90-30 system requires straightforward installation. It works alongside other modules like the IS200AEBMG1AFB in broader GE automation architectures.

• Rack Compatibility: The CPU fits any Series 90-30 rack with appropriate power supply. It typically occupies the leftmost slot adjacent to the power supply.

• I/O Support: It controls any combination of discrete, analog, and special function modules. Therefore, it suits diverse applications from simple to complex.

• Program Storage: The 240K memory supports large programs with extensive documentation. You can include detailed comments and rung descriptions.

• Firmware Updates: You can update the operating system through the serial port. This ensures access to the latest features and improvements.

• Battery Backup: A replaceable lithium battery maintains RAM during power outages. Typical battery life exceeds 5 years under normal conditions.
