The General Electric IC697CHS750 is a 5-slot I/O rack engineered for the Series 90-70 PLC architecture. This rear-mounting assembly serves as the foundational backplane for integrating various modules within the IC697 product family, providing both mechanical support and electrical connectivity for high-density industrial control applications.

Features

• 5-slot configuration for flexible I/O module arrangement.
• Designed for rear-panel mounting in enclosures with a minimum depth of 254 mm (10 inches).
• Compatible with the full range of IC697 series PLC modules, including CPU, I/O, and communication modules.
• Supports plug-in installation for both AC and DC IC697 power supply units.
• Features dedicated grounding studs on both the left and right sides to mitigate system electrical noise.
• Passive convection cooling design; no external fans required under standard operating conditions.

Technical Specifications

Installation Guidelines

• Ensure at least 6 inches of vertical clearance above and below the rack to facilitate unobstructed airflow for convection cooling.
• The rack is intended for indoor use within a protected industrial enclosure.
• Verify that the backplane is securely fastened to the mounting panel using the provided hardware.
• Properly terminate the grounding studs to the system earth ground to ensure effective noise immunity and operator safety.
• Always power down the system before installing or removing any I/O modules or power supply units from the rack slots.
• For high-density configurations where ambient temperatures are elevated, consider installing an optional 24 VDC Rack Fan Assembly to supplement passive cooling.

FAQ

What is the primary function of the IC697CHS750?

This unit acts as the main backplane for a GE Series 90-70 PLC system, providing the necessary bus communication and power distribution for up to five modules.

Does this rack require a specific power supply?

Yes, it is designed to accept standard plug-in IC697 series power supplies, which mount directly into the designated slot on the rack.

Are there special requirements for the enclosure?

The rack is designed for rear mounting and requires an enclosure depth of at least 254 mm (10 inches) to accommodate the hardware profile.

How is module addressing handled?

The IC697 system utilizes a backplane-based addressing scheme; modules do not require manual jumper or DIP switch configurations for slot addressing.
