This design allows industrial systems to accommodate more I/O points while maintaining reliable communication.
As part of the RX3i series, the IC694CHS398 aligns with GE’s legacy of rugged, field-proven solutions. It supports both standard and high-capacity power supplies (e.g., IC694PWR321 and IC694PWR330), ensuring compatibility with diverse power requirements. The backplane’s 25-pin female D-type expansion connector at the right-hand end facilitates daisy-chaining with other baseplates, enabling systems to scale from small setups to large-scale industrial applications. Key to its functionality is the rack number selection dip switch, which must be configured during installation to avoid addressing conflicts in multi-rack systems.
In automation systems, the IC694CHS398 plays a vital role in distributing control tasks across multiple racks. It supports a wide range of I/O modules (e.g., digital, analog, and specialty modules) while excluding certain option modules like PCM, CMM, ADC, and BEM 330, which require direct CPU integration. This modularity allows engineers to tailor systems to specific needs, whether in manufacturing, energy, or process industries. The IC694CHS398’s design prioritizes reliability, with a robust construction that withstands harsh industrial conditions, making it a preferred choice for mission-critical operations.

Main Features and Advantages: GE IC694CHS398
The GE IC694CHS398 stands out for its scalability and reliability, making it a cornerstone of modern industrial automation. Its 5-slot design allows systems to add up to five I/O modules per rack, while the 50-foot cable limit ensures signal integrity in distributed setups. Unlike some expansion backplanes, the IC694CHS398 supports a mix of I/O types, enabling engineers to consolidate control functions in a single system. For example, integrating analog modules for process monitoring and digital modules for machine control reduces hardware complexity and cabling costs.

For example, integrating analog modules for process monitoring and digital modules for machine control reduces hardware complexity and cabling costs.
Another key advantage is its compatibility with legacy and modern GE systems. The IC694CHS398 works seamlessly with GE’s Series 90-30 PLCs and newer RX3i PACSystems, allowing retrofits and upgrades without replacing entire control architectures. This backward compatibility is critical for industries where downtime during migration must be minimized. Additionally, the backplane’s rack addressing dip switch simplifies installation by eliminating manual configuration errors, a common pain point in multi-rack systems.
The IC694CHS398’s rugged construction ensures longevity in harsh environments. It resists vibrations, temperature fluctuations, and electromagnetic interference (EMI), common in manufacturing plants and power facilities. The absence of hot-swap support, while a limitation, ensures stable operation by preventing accidental module removal during system runtime. GE’s rigorous testing protocols further validate the IC694CHS398’s durability, making it suitable for 24/7 industrial operations.

Installation and Maintenance: GE IC694CHS398
Pre-installation Preparations:
Before installing the IC694CHS398, ensure the CPU baseplate is powered off and grounded. Verify the system’s power requirements and select the appropriate power supply (IC694PWR321 or IC694PWR330) based on the total current draw of installed modules. Configure the rack number dip switch on the IC694CHS398 to a unique address within the system’s range (0-7 for CPUs 350 and higher). Use a 25-pin D-type cable to connect the backplane to the CPU or other expansion racks, ensuring the cable length does not exceed 50 feet.

Maintenance Suggestions:
Regular maintenance is key to maximizing the IC694CHS398’s lifespan. Inspect the backplane quarterly for loose connections, corrosion, or physical damage. Clean dust and debris from the vents using compressed air to prevent overheating. If replacing modules, power off the system and ensure proper grounding to avoid electrostatic discharge (ESD) damage. For systems with redundant power supplies, test backup units annually to confirm functionality. In case of faults, refer to the IC694CHS398’s diagnostic LEDs for error codes, and replace faulty components with GE-approved spares (e.g., refurbished IC694CHS398 units from authorized distributors).
