Compatible Replacement & Equivalent Models
When the IS220YDOAS1A is unavailable or end-of-life, the following models may serve as functional equivalents or drop-in replacements depending on your system configuration. Always verify firmware and terminal compatibility before substitution.
- IS220YDOAS1B — Revised hardware revision; functionally equivalent, verify firmware compatibility
- IS220PDOAH1A — Alternative discrete output pack in the Mark VIe family; verify channel count and voltage rating
- IS200YDOAS1A — Mark VI predecessor; may require adapter or reconfiguration
- IS220YTDAS1A — Discrete I/O combination pack; suitable if mixed I/O is acceptable
- Third-party compatible modules — Contact Konmask.com for vetted cross-reference options
Note: Replacement selection must be validated against your Mark VIe system revision, IONet topology, and ToolboxST configuration. Konmask engineers can assist with compatibility verification.

Selection Guide
Use the following criteria to confirm the IS220YDOAS1A is the correct module for your application:
- Step 1 — Confirm platform: Verify your controller is Mark VIe (not Mark V or Mark VI)
- Step 2 — Check output type: IS220YDOAS1A provides discrete (digital) outputs — confirm your field devices require discrete signals
- Step 3 — Verify channel count: Match the number of output channels to your I/O requirements
- Step 4 — Review voltage rating: Confirm field device voltage compatibility (24 VDC logic)
- Step 5 — Check revision: Confirm hardware revision (A/B) matches your existing system or is backward compatible
- Step 6 — Contact Konmask: For cross-reference, obsolescence, or bulk procurement inquiries

Replacement & Compatibility FAQ
Q: Can IS220YDOAS1B replace IS220YDOAS1A directly?
A: In most cases yes — the B revision is a hardware update with the same functional profile. Verify with your ToolboxST configuration file before swapping.
Q: Is IS220YDOAS1A compatible with Mark VI (IS200 series)?
A: No. The IS220 series is designed exclusively for Mark VIe. Mark VI uses IS200-series I/O packs with a different backplane and communication protocol.
Q: Can Konmask provide a tested/refurbished unit?
A: Yes. We offer new surplus and refurbished (fully tested) units. Specify your preference when requesting a quote.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes, documentation including CoC and inspection report is available upon request.
Q: What is the lead time for bulk orders?
A: Contact us for volume pricing and lead time. We maintain stock of common Mark VIe I/O packs.
