EMERSON UNI1401 Digital Output Module | Replacement, Equivalent & Selection Guide
The EMERSON UNI1401 is a digital output (DO) I/O module designed for use within the Emerson Ovation Distributed Control System (DCS). It provides reliable discrete output control for industrial process automation environments, including power generation, oil & gas, and chemical processing plants. This page serves as a comprehensive selection, replacement, and compatibility reference for engineers and procurement teams sourcing the UNI1401 or its functional equivalents.

Compatible Replacement & Equivalent Models
When the UNI1401 is discontinued, obsolete, or unavailable, the following models may serve as functional replacements depending on your system configuration:
- EMERSON 5X00106G01 – Ovation Digital Output Module (direct platform equivalent)
- EMERSON 1X00024H01 – Ovation DO card, verify channel count and voltage compatibility
- EMERSON UNI1400 – Earlier revision; confirm firmware and backplane compatibility
- EMERSON UNI1402 – Later revision with potential enhanced diagnostics
- Westinghouse 1C31227G01 – Legacy equivalent for older Ovation/WDPF hybrid systems
Important: Replacement compatibility must be validated by a qualified DCS engineer. Backplane slot type, firmware version, and controller pairing all affect interchangeability.
Why Choose the Original EMERSON UNI1401

- ✅ Proven field reliability in mission-critical power and process plants
- ✅ Full Emerson software integration – no re-engineering of I/O maps required
- ✅ Optical isolation protects controller from field-side faults
- ✅ Hot-swap capable in supported Ovation chassis configurations
- ✅ Traceable sourcing available through Konmask.com with documentation
Typical Applications
- Power plant turbine and boiler control systems
- Oil & gas upstream/downstream process automation
- Chemical and petrochemical plant DCS I/O expansion
- Water treatment facility SCADA/DCS integration
- Pulp & paper mill process control
- Discrete valve, motor starter, and relay actuation via DCS
System Compatibility
The UNI1401 is designed for the Emerson Ovation DCS platform. Compatibility considerations include:
- Controller: Ovation OCR400, OCR1100, OCR400E series (verify per project BOM)
- I/O Chassis: Ovation standard and extended I/O cabinets
- Software: Emerson Ovation Developer Studio; I/O configuration via Ovation database
- Network: Ovation control network (proprietary Ethernet-based)
- Not compatible with: DeltaV, PROVOX, or third-party DCS platforms without engineering adaptation
Selection Guide
Use the following criteria to confirm the UNI1401 is the correct module for your application:
- Step 1 – Confirm platform: Verify your site runs Emerson Ovation DCS (not DeltaV or PROVOX)
- Step 2 – Check channel count: Confirm 16-point DO capacity meets your field device count
- Step 3 – Verify output voltage: Ensure field devices accept 24 VDC discrete signals
- Step 4 – Validate chassis slot: Confirm available I/O slot type in your Ovation cabinet
- Step 5 – Check firmware: Match controller firmware version with supported I/O module revisions
- Step 6 – Source documentation: Request datasheet, CE declaration, and test report from supplier

Replacement & Compatibility FAQ
Q: Is the UNI1401 still in production?
A: The UNI1401 may be in end-of-life or limited availability status. Contact Konmask.com to check current stock and lead times.
Q: Can I use a UNI1402 instead of a UNI1401?
A: Potentially yes, but firmware and backplane compatibility must be verified by your DCS engineer before substitution.
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-only supply.
Q: Can the UNI1401 be used in a DeltaV system?
A: No. The UNI1401 is Ovation-platform specific and is not compatible with Emerson DeltaV without significant re-engineering.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on sourcing.
