5-Slot Expansion Chassis | GE Fanuc 90-30 IC693CHS398

Product Overview

The GE Fanuc IC693CHS398 provides a robust, 100% Brand New expansion solution for Series 90-30 PLC systems. This 5-slot baseplate features EMI Enhanced shielding, specifically designed to maintain signal integrity in environments with high electromagnetic interference. It allows for the expansion of I/O capacity by connecting to a primary CPU baseplate via a high-speed expansion cable. Supporting up to five I/O or option modules and a dedicated power supply, the IC693CHS398 serves as a critical building block for distributed control architectures and localized I/O clusters.

Technical Specifications

Engineering Advantages

• Advanced EMI Protection: The "Enhanced EMI" design utilizes superior grounding and shielding techniques. This hardware mitigation prevents logic errors and data corruption caused by the electrical noise of high-power motors, variable frequency drives (VFDs), and heavy-duty switchgear.

• Scalable System Topology: Depending on the CPU model, you can daisy-chain multiple expansion baseplates. A CPU 350 system supports up to seven IC693CHS398 racks, allowing for massive I/O counts without the need for a secondary processor.

• Flexible Rack Addressing: Integrated DIP switches allow for manual rack ID assignment. This ensures the CPU correctly identifies and maps I/O points across the expansion bus, even in complex multi-rack configurations.

• Secure High-Speed Connectivity: The module uses a rugged 25-pin D-shell connector to secure the expansion cable. This physical locking mechanism prevents accidental disconnects in high-vibration industrial environments.

• Optimized Power Distribution: A dedicated unnumbered slot accommodates a standard Series 90-30 power supply. This local power delivery ensures that the expansion modules receive clean, stable 5V and 24V DC rails regardless of the distance from the main CPU rack.

FAQs

• What cables do I need to connect the IC693CHS398?

  You must use the IC693CBL series shielded expansion cables. Depending on your distance requirements, choose from the IC693CBL300 (1m), 301 (2m), 312 (0.15m), or 313 (8m). For the final rack in the chain, use the IC693CBL302 (15m) which includes a built-in terminator.

• Does this baseplate support the CPU module directly?

  No. The IC693CHS398 is an expansion baseplate and does not contain a CPU slot. It must connect to a "Base 0" (Primary) rack that houses the Series 90-30 CPU.

• How many of these expansion racks can I use in one system?

  This depends on your CPU. The CPU 331, 340, and 341 support up to four expansion racks, while the higher-performance CPU 350 and above support up to seven.
