GE IC693CHS391H Expansion Baseplate

Configured for local sub-rack I/O expansion and high-speed signal routing in Series 90-30 PLC platforms, the GE Fanuc IC693CHS391H (IC693CHS391 Expansion Baseplate) provides direct physical/electrical execution. It provides 10 module slots to interface a power supply, CPU or specialty module, and nine I/O option cards.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The GE Fanuc IC693CHS391H expansion baseplate manages deterministic backplane bus communication velocity across all 10 card slots. Backplane trace geometry and multi-layer bus arbitration maintain signal integrity for discrete, analog, and communication cards operating across slots 1 through 10. The 25-pin female D-shell connector enables deterministic expansion chaining, maintaining system timing synchronization and firmware flash compatibility across connected sub-racks.

Frequently Asked Questions

Q: What is the backplane current draw of the IC693CHS391H baseplate logic?

A: The IC693CHS391H internal backplane logic draws 420 mA from the 5 VDC bus supplied by the attached power supply module.

Q: Can the IC693CHS391H expansion baseplate operate without a power supply module installed?

A: No. A compatible Series 90-30 power supply module must be installed in the unnumbered left slot to power the backplane bus and adjacent I/O modules.

Field Installation Guidelines

1. Mount the IC693CHS391H baseplate to the enclosure backpanel using standard mounting screws to ensure low-impedance metal chassis grounding.
2. Install the power supply module into the unnumbered far-left slot prior to inserting I/O or option modules into slots 1 through 10.
3. Attach the 25-pin expansion bus cable to the female D-shell connector and hand-tighten the retention screws to prevent vibration disconnects.
4. Maintain physical segregation between high-voltage AC wiring and the expansion bus cable to avoid EMI noise coupling onto the backplane bus.
