Compatible Replacement & Equivalent Models
If the IC693ACC307 is unavailable or discontinued, the following models may serve as functional equivalents or replacements depending on your system configuration. Always verify compatibility with your specific rack and firmware revision before substitution.
- IC693ACC307A — Revised version of IC693ACC307; direct drop-in replacement in most configurations
- IC693CBL300 — I/O expansion cable; used in conjunction with terminator in multi-rack setups
- IC693CBL301 / IC693CBL302 / IC693CBL303 — Expansion bus cables of varying lengths; terminator required at end of chain
- Third-party equivalents — Some aftermarket suppliers offer compatible bus terminator plugs; confirm pin-out and impedance match before use
Note: Konmask.com recommends using genuine GE parts wherever possible to ensure system integrity and warranty compliance.

- Spare parts inventory for maintenance and MRO operations
- System integrators building or servicing GE-based control panels
System Compatibility
The IC693ACC307 is designed exclusively for the GE Series 90-30 PLC platform. It is not compatible with Series 90-70, VersaMax, or PACSystems platforms without hardware adaptation. Confirm your rack model (e.g., IC693CHS391, IC693CHS392, IC693CHS397) before ordering.
- Compatible Racks: IC693CHS391, IC693CHS392, IC693CHS397, IC693CHS398, IC693CHS399
- Not Compatible With: Series 90-70 (IC697 series), VersaMax (IC200 series), PACSystems RX3i/RX7i
Selection Guide
Use this guide to determine whether the IC693ACC307 is the right part for your application:
- Step 1 — Identify your PLC platform: Confirm you are using a GE Series 90-30 system (CPU models IC693CPU3xx or IC693CPU3xx).
- Step 2 — Count your expansion racks: A bus terminator is required at the last rack in any multi-rack I/O expansion chain.
- Step 3 — Check existing terminator: If your system is experiencing I/O communication errors or bus faults, inspect the terminator plug for damage or improper seating.
- Step 4 — Confirm part revision: IC693ACC307 and IC693ACC307A are functionally equivalent; either is acceptable for most installations.
- Step 5 — Contact Konmask: If you are unsure, send us your rack model and CPU part number and our team will confirm compatibility.

Replacement & Compatibility FAQ
Q: Can I use IC693ACC307A instead of IC693ACC307?
A: Yes. The “A” suffix denotes a minor revision. Both are functionally interchangeable in standard Series 90-30 configurations.
Q: What happens if I don’t use a bus terminator?
A: Without proper termination, the I/O expansion bus may experience signal reflections, leading to intermittent I/O faults, communication errors, or system instability.
Q: Is this part still in production by GE?
A: GE Fanuc’s Series 90-30 line has been largely superseded by PACSystems. The IC693ACC307 may be available as new surplus or refurbished. Contact us for current stock status.
Q: Can I use this terminator with a VersaMax rack?
A: No. VersaMax (IC200 series) uses a different bus architecture and requires its own terminator components.
Q: Do you provide a warranty?
A: Yes. We offer a 90-day warranty on all parts. Refurbished units include a 30-day warranty. Contact support for claims.
