The IC697CPX935 is a Central Processing Unit (CPU) module for the 90-70 Programmable Logic Controller (PLC) of the GE Fanuc series under General Electric (GE). The following is its detailed information:
- Processor: Adopts a 96MHz 80486 DX4 microprocessor, capable of performing a floating-point operation every 0.4 microseconds. It has strong computing power and can meet the real-time requirements of complex industrial automation control tasks.
- Memory: On-board 1MB RAM, powered by the IC697ACC701 battery to ensure no data loss in case of power failure. It also supports up to 256KB of user Non-Volatile Random-Access Memory (NVRAM) for storing user data and system firmware. The system firmware is stored in flash memory, eliminating the need to disassemble the module or replace the EPROM during updates.
- Dimensions and Weight: Measures 4.4cm × 29.2cm × 22.2cm and weighs approximately 0.5kg. Its compact design makes it suitable for installation in control cabinets with limited space.
- Communication Interfaces: Equipped with 3 serial ports, including RS-232 and RS-485 interfaces. It supports multiple communication protocols such as the SNP slave protocol, enabling convenient data communication and interaction with other devices like intelligent modules and upper computers.
- I/O Support: Can support any combination of 12K input/output points and can accommodate up to 8K analog I/O points. It can meet the I/O requirements of industrial automation systems of different scales and types, handling a large number of digital signals and precise analog control with ease.
- Operating Modes: Operated via a 3-position run/stop control switch, or can be controlled by connecting a computer running the corresponding software, facilitating on-site operation and remote control.
- Safety and Protection: Operation settings can be protected by a software password on the programming computer or a memory protection switch on the device itself, preventing unauthorized operations and parameter modifications and enhancing the system's safety and stability.
- Temperature Range: The operating temperature range is 0°C to 60°C. When the ambient temperature exceeds 50°C, a cooling fan with a minimum air volume of 70 cubic feet per minute must be installed to ensure the normal operation of the device.
- Power Requirements: The rated current drawn from the 5V bus is 3.1A.
- Battery Characteristics: The battery has a shelf life of 5 years at 20°C, and can maintain memory data for 6 months without power supply.
