Selection Guide
Use the following criteria to confirm the IC694MDL660-CC is the correct module for your application, or to identify the best alternative:
- Field voltage: 24VDC → IC694MDL660-CC ✓ | 120VAC → consider IC694MDL670 | 240VAC → consider IC694MDL671
- Point count required: 32 points → IC694MDL660-CC ✓ | 16 points → IC694MDL655 | 8 points → IC694MDL651
- Slot budget: Single slot preferred → IC694MDL660-CC ✓ (32 pts/slot, best density)
- Revision sensitivity: If your system was configured with an earlier revision (-CA/-CB), the -CC is backward compatible in all standard configurations
- Budget vs. OEM: For cost-sensitive MRO, third-party equivalents may be considered; for critical production systems, OEM sourcing is recommended

Replacement & Compatibility FAQ
Q: Can I replace IC694MDL660-CA with IC694MDL660-CC?
A: Yes. The -CC revision is backward compatible with -CA and -CB in all standard Series 90-30 configurations. No programming changes are required.
Q: Is IC693MDL660 the same as IC694MDL660-CC?
A: They are functionally equivalent but belong to different catalog families (IC693 vs IC694). Verify your baseplate catalog number before substituting.
Q: Can I use this module with a Series 90-70 or PACSystems RX3i system?
A: No. The IC694MDL660-CC is designed exclusively for the Series 90-30 backplane architecture and is not compatible with Series 90-70 or RX3i platforms.
Q: What wiring terminal block is required?
A: The IC694MDL660-CC uses a 40-pin removable terminal block (IC693ACC300 or equivalent). Confirm terminal block availability when ordering.
Q: Do you supply new, refurbished, or surplus units?
