Compatible Replacement & Equivalent Models
When the HE693THM166E is unavailable or discontinued, the following models may serve as functional replacements depending on your system configuration. Always verify firmware and rack compatibility before substitution.
- GE IC693CMM321 – Series 90-30 Ethernet Interface Module (standalone Ethernet, no onboard memory expansion)
- GE IC693CMM311 – Series 90-30 Ethernet TCP/IP Module (alternative communication card)
- Horner HE693THM128E – Lower memory variant (128KB), same Ethernet interface
- Horner HE693THM256E – Higher memory variant (256KB), upward-compatible upgrade path
- GE IC693CPU374 – Integrated CPU with Ethernet port (full CPU replacement path for system upgrades)
Note: Replacement compatibility depends on your PLC firmware version, rack configuration, and application program. Contact Konmask.com for a pre-purchase compatibility assessment.

Selection Guide
Use the following criteria to determine if the HE693THM166E is the right module for your application:
- Memory Requirement: If your application program exceeds 128KB but is within 166KB, this module is the correct fit. For programs >166KB, consider the HE693THM256E.
- Ethernet Requirement: If you need both memory expansion and Ethernet TCP/IP on a single slot, this is the optimal choice over separate memory + communication modules.
- Rack Slot Budget: Single-slot solution — ideal for space-constrained racks.
- Budget vs. New System: For legacy Series 90-30 systems still in production, replacing with an original HE693THM166E is more cost-effective than a full CPU upgrade.
- Upgrade Path: If planning a future migration to PACSystems RX3i, consult Konmask for a phased upgrade roadmap.

Replacement & Compatibility FAQ
Q: Can the HE693THM166E replace an IC693CMM321 directly?
A: Not directly — the CMM321 is a standalone Ethernet module without memory expansion. The HE693THM166E adds memory; verify your CPU’s memory addressing before substitution.
Q: Is this module compatible with PACSystems RX3i?
A: No. The HE693THM166E is designed exclusively for the Series 90-30 backplane. PACSystems RX3i uses IC695 series modules.
Q: Can I use a HE693THM256E as a drop-in replacement?
A: Yes, in most cases. The 256E is upward-compatible with the 166E slot position, but verify your application program does not reference memory addresses beyond the 166KB boundary.
Q: Do you supply refurbished units?
A: We supply both new and tested-surplus units. Condition is clearly stated on each listing. All units carry our 90-day warranty.
Q: How do I verify authenticity?
A: Each unit ships with its original GE/Horner label intact. We provide inspection photos and, upon request, third-party test reports.
