The General Electric IC698CHS009 is a 9-slot I/O rack designed for the PACSystems RX7i series. It serves as the central backplane for the system, facilitating high-speed data communication and power distribution across CPUs, I/O modules, and power supplies. Engineered to support both modern RX7i components and legacy Series 90-70 I/O modules, this rack provides a flexible, high-bandwidth VME64 architecture for demanding industrial automation environments.

Features

• 9-slot capacity for RX7i CPUs, I/O modules, and power supplies.
• VME64 backplane architecture for high-speed I/O throughput.
• Slot-sensing capability eliminates the need for manual DIP switches or jumpers for I/O addressing.
• Automatic daisy-chaining of interrupt acknowledgement and bus grant signals.
• Supports both 100W (convection-cooled) and 350W (fan-assisted) power supply modules.
• Compatible with standard VME modules and Series 90-70 I/O devices.

Applications

• Automotive assembly lines and robotic control systems.
• Power utility substations and water treatment facilities.
• Heavy machinery control in metal and steel production.
• Automated batching and high-volume packaging in food and beverage processing.
• Refinery safety and chemical process control.

Technical Specifications

Installation Guidelines

• Ensure the rack is mounted in an enclosure rated for the operating environment (minimum IP 54).
• Use the #8-32 ground studs located on the sides of the rack for chassis grounding.
• Connect to earth ground using a minimum of AWG #12 (3.3 mm²) wire, utilizing a ring terminal and star washer for a secure connection.
• If using a 350W power supply, an optional fan assembly (e.g., IC698CPE020/CRE020) is required for adequate cooling.
• Always power down the rack before inserting or removing any CPU or I/O modules to prevent electrical damage.

FAQ

What is the IC698CHS009?

The IC698CHS009 is a 9-slot rear-mount rack for the GE Fanuc PACSystems RX7i series. It acts as the backbone of the PLC system, managing data and power distribution across all installed modules.

What power supplies are compatible?

The rack is designed to support RX7i power supplies, specifically the 100W convection-cooled units and the 350W units which require active cooling.

How are modules addressed in this rack?

The rack features automatic slot-sensing technology, which eliminates the need for manual configuration via DIP switches or jumpers.

Can I use double-width modules?

Yes, slot 9 is specifically designed to accommodate double-width modules (40.6 mm wide).

Is this rack compatible with older Series 90-70 modules?

Yes, the IC698CHS009 is designed for backward compatibility, allowing the integration of Series 90-70 I/O and standard VME modules alongside newer RX7i hardware.
