Compatible Replacement & Equivalent Models
The following models are functionally equivalent or drop-in replacements for the IC694MDL645D. Always verify firmware revision and backplane compatibility before substitution.
- IC694MDL645E – Revised version (D→E suffix); same I/O count and voltage range, updated firmware. Preferred direct replacement.
- IC694MDL645 – Earlier revision without suffix; functionally identical, may lack latest firmware patches.
- IC694MDL646 – 32-point 12/24 VDC sinking output variant; use when load wiring polarity is reversed.
- IC694MDL660 – 16-point 120 VAC output module; suitable if AC field devices are required instead of DC.
- IC694MDL754 – 32-point 24 VDC output, higher current (1 A/point); select when higher per-point load is needed.
- Horner HE693MDL645 – Third-party equivalent for Series 90-30 backplanes; verify RX3i compatibility before use.
Note: Suffix letters (A/B/C/D/E) denote hardware revisions. Later revisions are backward compatible in most applications.
Why Choose the Original Model
- Guaranteed OEM compatibility with GE PACSystems RX3i CPU and backplane firmware.
- Full GE Proficy Machine Edition support – no additional driver configuration required.
- Proven field reliability in continuous 24/7 industrial environments.
- Optical isolation protects PLC logic from field-side voltage transients and ground loops.
- Sourcing output type simplifies wiring for standard NPN-load devices common in Asian and European markets.
Typical Applications
- Conveyor and material handling control (solenoid valves, motor starters)
- Packaging line actuator control
- Automotive assembly line I/O expansion
- Water and wastewater pump station control
- Building automation and HVAC damper control
- Oil & gas wellhead and pipeline valve control
System Compatibility
- Primary Platform: GE PACSystems RX3i (IC695 CPU series)
- Legacy Platform: GE Series 90-30 (IC693 CPU series) – backplane compatible
- Programming Software: GE Proficy Machine Edition 8.x and above
- Communication: Via RX3i backplane bus; no separate fieldbus required
- Power Supply: Requires 24 VDC field power supply (user-supplied)
- Not compatible with: PACSystems RSTi-EP, VersaMax, or Series Six platforms
Selection Guide
Use the decision criteria below to confirm IC694MDL645D is the correct choice, or to identify the best alternative:
- Output count needed: 32 points → IC694MDL645D ✓ | 16 points → IC694MDL660 or IC694MDL740
- Output voltage: 12/24 VDC → IC694MDL645D ✓ | 120 VAC → IC694MDL660
- Output polarity: Sourcing (PNP) → IC694MDL645D ✓ | Sinking (NPN) → IC694MDL646
- Per-point current: ≤0.5 A → IC694MDL645D ✓ | ≤1 A → IC694MDL754
- Platform: RX3i or Series 90-30 → IC694MDL645D ✓ | RSTi-EP → use IC695 series modules
- Budget/availability: If OEM lead time is long, IC694MDL645E (latest revision) or Horner equivalent may be sourced faster.

Replacement & Compatibility FAQ
Q: Can IC694MDL645E replace IC694MDL645D directly?
A: Yes. The E revision is backward compatible and is the preferred replacement. No configuration changes are required in Proficy Machine Edition.
Q: Will IC694MDL645D work in a Series 90-30 rack?
A: Yes. The IC694 series shares the same backplane form factor as IC693 (Series 90-30). Verify CPU firmware supports the module revision.
Q: Is the output sourcing or sinking?
A: Sourcing (PNP). For sinking (NPN) loads, use IC694MDL646 instead.
Q: What is the maximum load per output point?
A: 0.5 A per point, with a group maximum of 4 A for each 16-point group.
Q: Do you supply refurbished units?
A: We supply both new and tested-used units. Condition is clearly stated on each listing. Contact us if you require new OEM-sealed stock.
Q: Can I get a datasheet or wiring diagram?
A: Yes. Email support@konmask.com with your part number and we will provide the GE technical documentation.
