Compatible Replacement & Equivalent Models
Direct Drop-in Replacements
- Honeywell 51305887-150 (same P/N, different label revision) — Identical form, fit, and function. Confirm hardware revision matches your existing rack.
- Honeywell MC-TAIH14 (bare module reference) — Same assembly, sourced through authorized Honeywell channels or certified distributors.
Functional Equivalents (same platform, similar function — verify before installation)
- Honeywell 51304453-150 / MC-TAIH02 — Earlier-generation TPS battery module; verify voltage and connector compatibility before substitution.
- Honeywell 51309512-175 — Used in some TPS High-Performance Process Manager (HPM) nodes; confirm node type before ordering.
Cross-Brand Alternatives (functional substitute — requires engineering review)
- ABB / Bailey INNIS01 battery backup — Used in Infi-90 DCS; not a direct substitute but serves equivalent backup function in cross-platform migration projects.
- Emerson / Fisher-Rosemount DeltaV battery modules — Applicable only in full platform migration scenarios; not interchangeable at the module level.
⚠ Prerequisites & Cautions: Always verify hardware revision, connector pinout, and battery chemistry before substitution. Cross-brand alternatives require full engineering validation. Contact Konmask for a compatibility assessment before ordering.
Why Choose the Original MC-TAIH14 Model
- Precision Compatibility: Engineered specifically for TPS/TDC 3000 card-cage architecture — zero integration risk.
- OEM Certifications: Carries Honeywell platform-level CE and UL certifications, satisfying site safety audits without additional validation.
- Firmware & Hardware Alignment: Matched to TPS system firmware revisions, preventing undocumented behavior from third-party substitutes.
- Technical Support: Backed by Honeywell’s global service network and Konmask’s pre/post-sales engineering support.
- Warranty Coverage: Genuine modules carry manufacturer warranty; refurbished units from Konmask include a 12-month tested warranty.
- Long-Term Availability: Konmask maintains stock of legacy TPS modules, reducing exposure to spot-market counterfeits.
Typical Applications
- Petrochemical Refineries: Backup power for TPS controller nodes managing distillation column control loops.
- Power Generation Plants: Battery backup in TDC 3000 systems controlling turbine governor and boiler management.
- Pulp & Paper Mills: Sustaining I/O module power during grid fluctuations in continuous process lines.
- Pharmaceutical Manufacturing: Ensuring uninterrupted DCS operation in GMP-regulated batch processing environments.
- Chemical Plants: Protecting safety-critical control loops from power transients in exothermic reaction management.
- LNG & Offshore Platforms: Providing battery backup redundancy in remote TPS installations with limited grid stability.
System Compatibility
- Honeywell TPS / TDC 3000 Platform — Primary target system; module is native to this architecture.
- MC-GPIM01 / MC-GPIM02 (Global Personality Interface Module) — Shares the same card-cage environment; battery module supports shared power rail.
- MC-PAIH03 / MC-PAIH04 (Analog Input Modules) — Co-located I/O modules that rely on battery backup during power events.
- 51304453-xxx Series Power Supply Modules — Primary power source; MC-TAIH14 acts as secondary/backup in the same chassis.
- Honeywell HPM (High-Performance Process Manager) — Compatible node type; verify slot assignment per system documentation.
- TPS Universal Control Network (UCN) — Battery module supports node availability on the UCN during transient power loss.
Selection Guide
Answer these three questions to confirm the MC-TAIH14 is the right module for your system:
- Platform Match: Is your DCS a Honeywell TPS or TDC 3000 system? If yes, the MC-TAIH14 is the correct battery module family. If you are on Experion PKS or C300, a different module applies — contact Konmask for guidance.
- Hardware Revision: What is the hardware revision of your existing battery module or chassis? Confirm the 51305887-xxx suffix matches your system’s BOM to avoid revision mismatches.
- Replacement vs. Equivalent: Do you need an exact OEM replacement (same P/N), or will a tested functional equivalent suffice? Konmask can supply both — specify your requirement and we will confirm availability and lead time within 24 hours.

Replacement & Compatibility FAQ
Q1: Can I use a 51304453-150 as a direct replacement for the MC-TAIH14 51305887-150?
A: The 51304453-150 is an earlier-generation Honeywell battery module and may be a functional equivalent in some TPS configurations, but it is not a guaranteed drop-in substitute. Connector pinout and voltage specifications must be verified against your chassis documentation before installation. Konmask can provide a compatibility assessment.
Q2: Is the MC-TAIH14 compatible with Honeywell Experion PKS systems?
A: No. The MC-TAIH14 is designed for the TPS/TDC 3000 platform. Experion PKS uses a different controller and power architecture. If you are migrating from TPS to Experion, contact Konmask for the correct equivalent module for your target platform.
Q3: What is the substitute for MC-TAIH14 if the original is no longer available?
A: Konmask maintains tested surplus stock of the MC-TAIH14 and its functional equivalents. If the exact P/N is unavailable, we can recommend a validated substitute based on your system’s hardware revision and node type. Email support@konmask.com with your system details for a same-day response.
