The General Electric IC697CHS790 is a robust 9-slot mounting rack designed for the Series 90-70 Programmable Logic Controller (PLC) architecture. This baseplate provides a reliable foundation for CPU, communication, and I/O modules within the IC697 system, supporting flexible, high-density industrial control configurations.
Features
- Nine (9) dedicated slots for I/O and processor modules, plus one (1) dedicated power supply slot.
- Compatibility with all standard IC697 PLC module types.
- Supports system expansion by allowing two racks to be interconnected to share a single power supply unit (requires IC697CBL700 cable kit).
- Integrated slot sensing technology eliminates the need for physical module jumpers or DIP switches for addressing.
- Designed for rear-panel mounting in 10-inch deep enclosures.
- Rack identification configured via four jumpers located on the backplane behind the power supply.

Installation Guidelines
- Ensure the rack is mounted in an environment with adequate ventilation; while fans are generally not required, maintain clearance for heat dissipation.
- Power down the system completely before inserting or removing any I/O or power supply modules to prevent electrical damage.
- Assign a unique rack number (0 to 7) using the backplane jumpers; the CPU rack must always be designated as Rack 0.
- When interconnecting multiple racks, ensure the total power consumption does not exceed the capacity of the shared power supply module.
- Use appropriate ESD-safe handling procedures when installing modules into the rack slots to prevent damage to sensitive backplane components.
FAQ
How do I configure I/O addressing for this rack?
I/O point references and slot addressing are handled entirely through software, such as Logicmaster 90-70 or Proficy Machine Edition. There are no physical DIP switches or jumpers required on the individual I/O modules.
Can I use this rack for turbine control applications?
Yes, the IC697CHS790 serves as a standard backplane for various GE automation systems, including turbine control and monitoring, process manufacturing, and high-speed fluid control networks.
What is the purpose of the leftmost slot?
The leftmost slot is specifically reserved for the installation of a plug-in AC or DC IC697 power supply module.
