Honeywell MC-TAIH22 (51204170-250) – High Level Analog Input Module | TDC 3000 / Experion PKS
Engineering Background
The Honeywell MC-TAIH22, part number 51204170-250, is a high-level analog input module engineered for Honeywell’s TDC 3000 and Experion PKS distributed control system (DCS) platforms. Designed to meet the rigorous demands of continuous process industries, this module provides reliable, high-accuracy analog signal acquisition for critical control loops in refining, petrochemical, power generation, and advanced manufacturing environments.
Product Positioning
As a direct replacement and spare component for legacy TDC 3000 and Experion PKS installations, the MC-TAIH22 enables engineers to maintain system integrity without costly platform migrations. Konmask.com sources, inspects, and verifies each unit to ensure full functional compliance with Honeywell’s original factory specifications.

Engineering Advantages
- Drop-in Replacement: 100% hardware and firmware compatible with existing TDC 3000 and Experion PKS I/O racks — no reconfiguration required.
- High Channel Density: Maximizes rack utilization and reduces per-channel cost in large-scale DCS installations.
- Galvanic Isolation: Protects the control bus from field-side transients and ground loops, ensuring signal integrity.
- Proven Reliability: Honeywell’s HIOM architecture has a documented MTBF exceeding 200,000 hours in continuous process service.
- Backward Compatibility: Supports both legacy TDC 3000 and modern Experion PKS migration paths without hardware redesign.
System Architecture & Signal Flow
The MC-TAIH22 installs directly into a standard Honeywell I/O carrier/rack assembly. Field transmitter signals (4–20 mA or 1–5 VDC) are wired to the module’s field termination assembly (FTA). The module performs A/D conversion, applies engineering unit scaling, and transmits process values over the Honeywell UCN/LCN backplane to the controller node (HPM/C200/C300). Redundant module configurations are supported via the standard Honeywell redundancy scheme, enabling bumpless switchover without process interruption.
