Compatible Replacement & Equivalent Models
When the IOP365 is discontinued, obsolete, or on extended lead time, the following models may serve as functional equivalents or drop-in replacements depending on your system configuration:
- Metso IOP360 – Earlier generation isolated analog input; verify channel count and resolution compatibility
- Metso IOP366 – Higher-density variant; may require firmware update on the controller side
- Valmet DNA AI Module (post-rebrand) – Direct successor under Valmet branding; confirm part mapping with Valmet support
- Honeywell HC900 AI Module – Cross-platform alternative for system migrations; requires I/O mapping reconfiguration
- ABB AI810 / AI820 – Suitable for cross-brand DCS migration projects with engineering adaptation
- Siemens ET 200SP AI Module – For greenfield or brownfield projects transitioning to Siemens TIA Portal architecture
Note: Always verify signal range, isolation class, backplane compatibility, and firmware version before substituting any module. Contact Konmask for pre-sales compatibility assessment.

Selection Guide
Use the following criteria to determine whether the IOP365 is the right module for your application:
- Channel Count: Confirm required number of isolated analog input channels matches IOP365 specification
- Signal Range: Verify field instruments output 4–20 mA or 0–10 V compatible signals
- Isolation Requirement: If ground loops or high common-mode voltage are present, galvanic isolation is mandatory
- DCS Platform: IOP365 is native to Metso DNA; for other platforms, consult the replacement table above
- Spare Parts Strategy: For aging Metso DNA systems, stocking 1–2 IOP365 spares is recommended to minimize unplanned downtime
- Obsolescence Risk: If IOP365 is approaching end-of-life in your region, consider Valmet DNA equivalent or plan a phased migration

Replacement & Compatibility FAQ
Q: Can the IOP365 be used in non-Metso DCS systems?
A: Not directly. The IOP365 uses Metso’s proprietary backplane bus. Cross-platform use requires a gateway or full I/O migration project.
Q: Is the IOP365 still in production?
A: Metso has rebranded to Valmet. Availability varies by region. Contact Konmask for current stock status and Valmet equivalent part numbers.
Q: What is the difference between IOP365 and IOP366?
A: The IOP366 typically offers a higher channel density or updated isolation architecture. Confirm with your Metso DNA system documentation before substituting.
Q: Can I mix IOP365 with newer Valmet DNA I/O modules in the same rack?
A: In most cases yes, subject to backplane revision compatibility. Verify with your Valmet/Metso site engineer or contact Konmask for guidance.
Q: Do you provide a certificate of conformance?
A: Yes. A certificate of conformance and test report are available upon request for all units shipped from Konmask.
