Compatible Replacement & Equivalent Models
If the SNAP-AIV-8 is discontinued, long lead-time, or out of budget, the following models offer functional equivalence or drop-in compatibility:
- OPTO 22 SNAP-AIV-4 — 4-channel version; same voltage range, same backplane; use two units to match 8-channel capacity
- OPTO 22 SNAP-AIMA-8 — 8-channel analog input, milliamp (4–20 mA) variant; suitable when signal type can be converted
- OPTO 22 SNAP-AIV32-8 — higher-density 32-channel variant for large-scale systems
- Advantech ADAM-6017 — 8-channel analog input module with Modbus TCP; requires gateway integration
- Wago 750-459 — 8-channel ±10 V analog input for Wago 750 fieldbus coupler; compatible via Modbus mapping
- Phoenix Contact AXL F AI8 I 1H — 8-channel analog input for Axioline F system; requires protocol adapter
Note: Third-party replacements may require firmware configuration or signal conditioning. Contact Konmask for pre-sales compatibility verification.

Replacement & Compatibility FAQ
Q: Can I use SNAP-AIV-8 with legacy SNAP-LCE brains?
A: No. The SNAP-AIV-8 is designed for SNAP PAC generation brains only. For legacy systems, consult OPTO 22’s migration guide or contact Konmask for alternatives.
Q: Is SNAP-AIV-8 compatible with ±5 V signals?
A: The module is rated for ±10 VDC. ±5 V signals are within range and will be read accurately, but resolution is effectively halved. Consider SNAP-AIV-4 with software scaling for precision applications.
Q: What is the lead time for SNAP-AIV-8?
A: In-stock units ship within 1–3 business days. For large quantities or special configurations, contact us for availability.
Q: Can Konmask provide a Certificate of Conformance (CoC)?
A: Yes. CoC and test reports are available for qualified B2B orders upon request.
Q: Are third-party replacements covered under warranty?
A: Third-party equivalents carry their respective manufacturer warranties. Konmask provides a 90-day functional guarantee on all verified surplus units.
