The GE IC698CHS117 is a 17-slot, front-mount rack for the PACSystems RX7i series of Programmable Logic Controllers (PLCs), now a part of Emerson Automation. It serves as the physical and electrical foundation for a large-scale RX7i control system.
Key Features and Specifications
- Slot Configuration: The rack has a total of 17 slots. The slot assignments are as follows:
- Slot 0: This is the leftmost, dedicated slot for the power supply module.
- Slot 1: This is the dedicated slot for the CPU module.
- Slots 2-16: The remaining 15 slots are available for various I/O and specialty modules.
- Mounting: The IC698CHS117 is a front-mount or “panel-mount” rack. This design allows for module insertion, removal, and wiring from the front of the control panel, which is convenient for maintenance and installation in situations where rear access is limited.
- Compatibility: The rack is highly versatile and is compatible with a variety of module types, including:
- RX7i CPUs and I/O modules.
- Series 90-70 I/O modules.
- VME modules (with specific guidelines).
- High-Speed Backplane: The rack features a high-speed backplane that facilitates fast and efficient data exchange between the CPU and all the modules. It provides automatic daisy-chaining of interrupt signals and bus grants, which simplifies configuration.
- Power Supply Support: It can accommodate both 100W and 350W rated RX7i power supplies to meet the power requirements of large, complex systems.
- Open Equipment: The rack is considered “open equipment” and must be installed in a protective enclosure rated IP54 or greater to protect it from dust and water in industrial environments.
Applications
The IC698CHS117 is a core component for building new or expanding existing RX7i PLC systems in applications that require a significant number of I/O points and high-performance control. Its front-mount design makes it particularly suitable for:
- Standard Control Cabinets: Where front access for wiring and maintenance is the norm.
- Large-scale Manufacturing Automation: For controlling complex processes and machinery.
- Process Control: In industries like oil and gas, and water treatment.
