Compatible Replacement & Equivalent Models
When the AUTONET HFAI-08 is unavailable or under evaluation, the following models may serve as functional equivalents depending on your system architecture. Always verify electrical compatibility, channel count, and backplane interface before substitution.
| Brand | Model | Channels | Signal Type | Notes |
|---|---|---|---|---|
| AUTONET | HFAI-16 | 16 DI | 24 VDC | Expanded channel version; same series |
| Siemens | 6ES7 321-1BH02-0AA0 | 16 DI | 24 VDC | S7-300 DI module; requires adapter for non-Siemens racks |
| Schneider Electric | 140DDI35300 | 32 DI | 24 VDC | Modicon Quantum series; higher channel density |
| Rockwell / Allen-Bradley | 1756-IB16 | 16 DI | 10–31.2 VDC | ControlLogix platform; different backplane |
| Mitsubishi | QX40 | 16 DI | 24 VDC | Q-series; requires Mitsubishi CPU rack |
Important: Cross-brand substitution requires engineering review. Konmask.com recommends using original AUTONET modules for warranty-compliant installations.
Why Choose the Original AUTONET HFAI-08
- Guaranteed compatibility with AUTONET PLC/DCS backplane and firmware
- Factory-calibrated signal thresholds for accurate discrete input detection
- Optocoupler isolation protects the controller from field-side voltage transients
- Plug-and-play replacement — no firmware reconfiguration required in same-series systems
- Traceable sourcing — all units at Konmask.com are verified original, not refurbished clones
Typical Applications
- Discrete signal acquisition from limit switches, proximity sensors, and push buttons
- Machine tool and CNC status monitoring
- Process plant interlocking and safety logic input
- Conveyor and material handling control systems
- Building automation and HVAC control panels
- Water treatment and utilities SCADA front-end I/O
System Compatibility
The HFAI-08 is designed for use within the AUTONET modular PLC/DCS platform. It slots into standard AUTONET I/O racks and communicates via the proprietary backplane bus. Confirm the following before ordering:
- AUTONET CPU series (e.g., HF series) supports HFAI-08 in its I/O configuration table
- Rack slot count and power budget accommodate an additional DI module
- Field wiring uses 24 VDC sourcing or sinking inputs as specified in the HFAI-08 wiring diagram
- Firmware version of the CPU is compatible with HFAI-08 module ID
Selection Guide
Use the decision criteria below to confirm the HFAI-08 is the right module for your application:
| Requirement | HFAI-08 Suitability |
|---|---|
| Need exactly 8 DI channels | ✅ Ideal fit |
| Need 16+ DI channels in one slot | ⚠️ Consider HFAI-16 instead |
| Using AUTONET HF-series CPU rack | ✅ Direct plug-in compatible |
| Using third-party PLC rack | ❌ Not compatible — use equivalent listed above |
| Require ATEX / hazardous area rating | ⚠️ Verify with AUTONET datasheet |
| Budget-sensitive replacement | ✅ Competitively priced at Konmask.com |
Quality Assurance & Sourcing
Konmask.com sources the AUTONET HFAI-08 directly from authorized distribution channels. Every unit undergoes the following before dispatch:
- Visual inspection for physical damage and label authenticity
- Packaging integrity check (original AUTONET anti-static packaging preferred)
- Serial number and batch traceability documentation available on request
- 30-day return window for DOA (Dead on Arrival) units
We do not sell refurbished, remarked, or counterfeit modules. If you require a Certificate of Conformance (CoC) or test report, contact us before ordering.
How to Order
- Confirm your AUTONET CPU model and rack configuration

Replacement & Compatibility FAQ
Q: Can the HFAI-08 replace an older AUTONET DI module with a different part number?
A: Possibly, if the backplane connector and module ID are compatible. Contact us with your existing module’s part number for a cross-reference check.
Q: Is the HFAI-08 compatible with Siemens or Schneider PLCs?
A: No. The HFAI-08 uses AUTONET’s proprietary backplane bus and is not physically or electrically compatible with third-party racks. See the equivalent models table above for alternatives.
Q: What is the lead time for the HFAI-08?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–6 weeks depending on AUTONET production schedules.
Q: Can I use the HFAI-08 for AC input signals?
A: The standard HFAI-08 is rated for DC inputs. Verify the exact input voltage range in the AUTONET HFAI-08 datasheet before connecting AC field devices.
Q: Do you provide installation support?
A: Konmask.com provides pre-sales technical consultation. For on-site commissioning, contact your local AUTONET system integrator.
