IC693CHS391 GE Fanuc Series 90-30 Datasheet & Technical Manual

GE Fanuc IC693CHS391 Series 90-30 Expansion Baseplate

Configured for specific technical tasks in Series 90-30 PLC platforms, the GE Fanuc IC693CHS391N (IC693CHS391 Expansion Baseplate) provides direct physical/electrical execution. The hardware operates as a passive backplane expansion frame equipped with 10 dedicated module slots alongside an unnumbered power supply slot. Lacking a central processing unit registration slot, this unit extends the primary system parallel bus through an expansion cable port, routing logic signaling lines and +5 VDC bus voltages across all inserted input, output, and specialty modules.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The IC693CHS391 provides the physical foundation for scaling system I/O density up to 10 discrete or analog modules per extended rack branch. While the backplane handles parallel data byte synchronization across its local traces, these data arrays interface directly with upstream Profinet or EtherNet/IP deterministic networks via master communication modules positioned on the primary baseplate. The localized connection maintains continuous timing sync during processing sweeps, verifying that all module parameter profiles maintain structural firmware flash compatibility across legacy and contemporary framework updates.

Frequently Asked Questions

Q: Can a standard Series 90-30 CPU module be inserted into any of the 10 slots on the IC693CHS391N?

A: No. This baseplate does not possess the necessary physical hardware architecture or tracing layout required to host a central processing unit. Slot 1 through Slot 10 are wired purely as peripheral subordinate expansion points; the master CPU must reside exclusively in slot 1 of a dedicated CPU baseplate.

Q: Is it safe to replace damaged I/O modules on this expansion baseplate while the main system remains energized?

A: No. The legacy backplane tracking arrays on the Series 90-30 modules do not incorporate current-limiting or electrical arc-suppression controls for live extractions. Pulling or inserting modules under load can cause data corruption on the expansion parallel bus, initiate master CPU safety shutdowns, or destroy logic-side isolation circuits.

Field Installation Guidelines

• Enclosure Mechanical Mounting: Ensure all incoming power lines are completely isolated before installation. Mount the baseplate horizontally inside a grounded metal panel enclosure using four mounting screws through the flange locations to ensure structural stability and reliable frame grounding.
• Power Supply Initialization: A dedicated Series 90-30 power supply module must be installed into the unnumbered left-hand slot of this chassis. This supply provides the isolated power necessary to run the localized backplane rails and internal module components.
• Expansion Cabling and Port Protection: Interconnect this unit to the upstream CPU chassis using standard shielded 25-pin expansion bus cables. Keep cable lengths within specified engineering thresholds, and route the serial bus lines away from high-current AC motor leads to suppress inductive noise injection.
• Slot-Based Address Configuration: Module addressing parameters are structurally bound to the physical slot index occupied on the backplane. Ensure that the hardware slot positions match the exact I/O configuration matrix defined within the PLC development software.
