GE IC693CBL305 Cable Port Expansion | Replacement, Equivalent & Selection Guide
The GE IC693CBL305 is a Cable Port Expansion module designed for use within the GE Series 90-30 PLC system (also marketed as GE Fanuc Series 90-30). It provides additional serial communication port capacity to the CPU or expansion rack, enabling multi-device connectivity in distributed industrial control architectures.
Whether you are sourcing a direct replacement for a failed unit, evaluating a functionally equivalent alternative, or performing a cross-brand substitution during a system upgrade, this guide covers everything you need to make a confident, spec-accurate procurement decision.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
These are OEM or remanufactured units with identical part numbers and form factor. They can be swapped without any configuration change:
- IC693CBL305 (new OEM, refurbished, or surplus) — identical hardware revision required; confirm firmware compatibility with your CPU firmware version
- GE Fanuc-branded IC693CBL305 (pre-Emerson era) — functionally identical; verify label and hardware revision
2. Functional Equivalents
Modules that perform the same cable port expansion function within the Series 90-30 ecosystem but may differ in connector layout or firmware requirements. Verify slot compatibility and CPU firmware before substitution:
- IC693CBL300 — earlier revision cable assembly; confirm pin-out and length compatibility
- IC693CBL301 / IC693CBL302 — variant cable lengths; same electrical interface, different physical reach
- Other IC693CBLxxx series cables — evaluate based on target port type and rack position
3. Cross-Brand Alternatives
For system migrations or when OEM parts are unavailable, the following platforms offer comparable serial port expansion capabilities. Note: Cross-brand substitution requires engineering review and is not a plug-and-play replacement.
- Siemens S7-300 CP 340 / CP 341 — serial communication modules for S7-300; requires full system migration
- Rockwell Allen-Bradley 1747-KE / 1747-SN — SLC 500 serial expansion; different backplane, not pin-compatible
- Schneider Electric TSX SCY 21601 — Modicon serial port module; protocol mapping required
- Prerequisite: Cross-brand alternatives require new rack, CPU, and I/O mapping. Contact Konmask for migration assessment.

- IC693MDL655 / IC693MDL753 — Representative I/O modules sharing the same rack; no conflict with cable port expansion
Selection Guide
Answer these three questions before ordering to confirm the IC693CBL305 is the right fit for your application:
- Is your PLC a GE Series 90-30 system? The IC693CBL305 is exclusively designed for Series 90-30 racks. If you are running a Series 90-70 or VersaMax system, a different cable module is required — contact Konmask for cross-reference.
- What serial protocol does your target device use (RS-232 or RS-485)? Confirm the port type on your CPU or expansion rack matches the IC693CBL305 interface. Mismatched protocols require a different IC693CBLxxx variant.
- What is your CPU firmware version? Some cable port expansion modules require minimum CPU firmware revisions. Provide your CPU part number and firmware version to Konmask for pre-order compatibility verification.

Replacement & Compatibility FAQ
Q1: Can I use the IC693CBL305 as a direct replacement for a failed cable port expansion module in my Series 90-30 system?
A: Yes — the IC693CBL305 is a direct replacement for any same-revision unit in a Series 90-30 rack. Confirm the hardware revision matches your existing module to avoid firmware conflicts. Konmask can verify compatibility before shipment.
Q2: Is the IC693CBL305 compatible with or equivalent to other IC693CBLxxx cable modules?
A: Functionally, other IC693CBLxxx variants (e.g., IC693CBL300, IC693CBL301) are equivalent in communication interface but differ in cable length and connector configuration. They are not always interchangeable — verify pin-out and physical length requirements before substituting.
Q3: Can I substitute the IC693CBL305 with a cable module from another PLC brand (e.g., Siemens or Allen-Bradley)?
A: Cross-brand substitutes are not plug-and-play equivalents. While Siemens CP 340 or Allen-Bradley 1747-KE modules perform similar serial expansion functions, they require different racks, CPUs, and software. Contact Konmask for a full migration assessment if you are considering a cross-brand replacement.
