The GE IC698CHS217 is a 17-slot, rear-mount rack with rear I/O access for the PACSystems RX7i series of Programmable Logic Controllers (PLCs), now a part of Emerson Automation. It’s a key component for building a robust and expandable control system in a large-scale industrial application.
Key Features and Specifications
- Slot Configuration: This rack features a total of 17 slots.
- Slot 0 is dedicated to the power supply module.
- Slot 1 is reserved for the CPU module.
- Slots 2-16 are available for I/O modules, communication modules, and other specialty modules.
- Rear Mounting: The rack is designed to be mounted to the rear of a control panel or enclosure. This mounting style is often chosen for applications where a clean front panel is desired, with wiring and module access from the back of the enclosure.
- Rear I/O Access: A defining feature of the IC698CHS217 is its rear I/O access. This means that in addition to the standard module connectors on the backplane, there are also dedicated connectors on the back of the rack for wiring to I/O modules. This allows for clean and organized wiring, as the field wiring can be routed directly to the back of the rack, separate from the front of the modules. An offset bracket is used to enable this rear access.
- High-Speed Backplane: The rack features a high-speed backplane that supports the VME64 standard, which allows for extremely fast data exchange (up to 64 bits per cycle) between the CPU and all the modules. This is crucial for high-performance applications.
- Compatibility: The rack is highly versatile and is compatible with a variety of modules, including:
- RX7i CPUs and modules.
- Series 90-70 modules.
- VME modules (following specific guidelines).
- Power Supply Support: It supports both the 100W and 350W rated RX7i power supplies to meet the power requirements of large, complex systems.
- Open Equipment: Like other RX7i racks, it is considered “open equipment” and must be installed within a protective enclosure rated IP54 or better to protect it from dust and water.
