What Is GE IC698CHS017?

GE IC698CHS017 is a 17-slot rear-mount rack designed for the PACSystems RX7i industrial control platform. Rather than functioning as a standalone PLC CPU or I/O module, the rack provides the physical and electrical backplane structure needed to install and interconnect compatible control modules.

The rack contains slots 1 through 17 for modules, with the CPU installed in slot 1 in a typical RX7i configuration. Slot 0 is reserved for the power supply and has a wider 2.4-inch opening. This arrangement gives engineers a centralized structure for building relatively large PLC configurations without requiring multiple small racks.

According to the technical documentation, the rack can accommodate RX7i I/O modules, VME modules, single-width Series 90-70 modules, and double-width Series 90-70 PLC modules when used according to the applicable integration guidelines.

For buyers researching the exact model, the GE IC698CHS017 product page can also be used to review supplier information and purchasing details.


What Are the Key Specifications?

The physical and electrical specifications of a PLC rack are important because incorrect rack dimensions, slot requirements, or power distribution can create problems during system design. The following table summarizes the major specifications associated with this model.

The rack documentation also identifies a front-mount counterpart, IC698CHS117. This distinction matters when replacing an existing rack because physical mounting orientation and cabinet access requirements can differ even when the slot architecture is similar.


How Does Its Rack Architecture Work?

The backplane is one of the most important parts of a PLC rack because it provides the communication path between installed modules. In this rack architecture, the backplane is designed around 0.8-inch module spacing, allowing compatible single-width modules to be positioned in a consistent arrangement.

Several architectural features make the rack suitable for complex automation installations:

  • 17 module positions: The rack provides substantial capacity for CPU, I/O, communication, and other supported modules.
  • Dedicated power supply position: Slot 0 is wider than standard module positions and is specifically designed for the power supply.
  • Slot sensing: Rack-type I/O modules can be identified by the rack configuration without requiring individual I/O modules to use jumpers or DIP switches for addressing.
  • Automatic signal daisy chaining: Interrupt acknowledge and bus grant signals can be automatically chained through the rack.
  • VME integration: J2 backplane connectors support high-speed VME transfers, subject to applicable VME integration guidelines.

These features are particularly relevant when engineers are maintaining or expanding established industrial control systems rather than designing an entirely new PLC architecture.


Which Modules Can It Support?

Compatibility should always be confirmed against the specific CPU, I/O, communication, power supply, and VME configuration before installation. The rack itself is designed to support several module families associated with the RX7i and legacy Series 90-70 environment.

Potentially supported configurations include:

  • RX7i CPU modules
  • RX7i I/O modules
  • Compatible single-width Series 90-70 modules
  • Compatible double-width Series 90-70 PLC modules
  • VME modules integrated according to the applicable VME guidelines
  • Compatible RX7i AC power supplies

Double-width Series 90-70 modules occupy two standard slot positions, so the actual number of modules that can be installed depends on the width of the selected modules. System designers should therefore calculate available slot space rather than simply counting installed devices.


What Are Its Main Advantages?

1. High Module Capacity

With 17 standard module positions in addition to the dedicated power supply position, the rack can accommodate a relatively extensive control configuration. This can be valuable for applications involving numerous digital, analog, communication, or specialized modules.

2. Useful for Legacy System Integration

Support for selected Series 90-70 modules makes the architecture relevant to modernization and maintenance projects where existing hardware cannot be replaced immediately. This can help engineering teams extend the useful life of established control infrastructure.

3. Structured Cabinet Installation

The 19-inch width and rear-mount design provide a standardized mechanical format for suitable industrial cabinets and enclosures. Before ordering, buyers should compare the rack dimensions and rear-access requirements with the available cabinet space.

4. VME Capability

VME support gives engineers additional integration possibilities where compatible VME modules are required. However, VME integration should follow the relevant hardware and software documentation rather than assuming that every VME module is automatically compatible.

5. Flexible Power Configuration

The RX7i rack architecture supports different power supply capacities. The technical documentation lists both 100-watt and 350-watt power supply configurations, allowing system designers to select a suitable power arrangement according to the connected modules.


Where Is It Commonly Used?

A 17-slot PLC rack is generally selected when an industrial control system requires more module capacity than a smaller rack can provide. Typical application environments can include:

  • Factory automation and production lines
  • Process control systems
  • Material handling equipment
  • Energy and utility control applications
  • Large machine control cabinets
  • Industrial equipment modernization projects
  • Legacy PLC maintenance and replacement programs
  • Control systems requiring compatible VME integration

For example, an engineering team upgrading an established production line may need additional I/O capacity while retaining compatible legacy modules. A 17-slot rack can provide the physical platform for reorganizing the control system while maintaining a familiar module-based architecture.


How Should Buyers Select and Verify This Rack?

Purchasing an industrial rack should involve more than checking the model number. Buyers should verify the complete system configuration before placing an order.

  1. Confirm the exact part number. Make sure the requirement is IC698CHS017 rather than the front-mount IC698CHS117 or another RX7i rack.
  2. Check mounting requirements. IC698CHS017 is the rear-mount version, so cabinet access must match the installation arrangement.
  3. Calculate slot usage. Remember that double-width modules consume two standard slot positions.
  4. Verify power requirements. Check the total current demand of the planned modules against the selected RX7i power supply.
  5. Review environmental requirements. The rack is considered open equipment and should be installed in a suitable protective enclosure according to the applicable installation documentation.
  6. Confirm module compatibility. Do not assume that every Series 90-70 or VME module can be installed without checking the relevant compatibility and integration documentation.
  7. Inspect replacement condition. For replacement or maintenance projects, verify whether the supplied unit is new, unused, refurbished, or previously installed.

These checks can reduce the risk of receiving a physically similar but technically unsuitable rack, especially in legacy automation projects where several GE rack models may look comparable.
