Proven Application Environments
- Oil & Gas Refining: Continuous monitoring of temperature, pressure, and flow transmitters across distillation and cracking units.
- Petrochemical Plants: Multi-loop analog acquisition for reactor temperature profiling and feed-forward control.
- Power Generation: Boiler and turbine analog signal collection in HPM-based control architectures.
- Pulp & Paper: Process variable monitoring in TDC 3000 legacy installations requiring long-term spare availability.
- Pharmaceutical Manufacturing: Validated process environments where module traceability and documentation are mandatory.
Engineering Advantages
- Direct Backward Compatibility: Plug-and-play replacement within existing TPS/TDC 3000 IOP card cages — no firmware or database changes required.
- High Channel Density: 16 differential analog inputs per module minimizes card cage slot consumption and reduces wiring complexity.
- Optical Isolation: Channel-to-bus isolation protects the controller backplane from field-side transients and ground loops.
- Proven Long-Term Reliability: Honeywell’s IOP module family is field-proven across 30+ years of continuous industrial deployment.
- Simplified Spare Management: Single module type covers a wide range of HLAI applications, reducing spare parts inventory complexity.
System Architecture & Signal Flow
The MC-TAIH22 resides in the I/O Processor (IOP) card cage and communicates with the High-Performance Process Manager (HPM) or Advanced Process Manager (APM) via the IOP backplane bus. Field transmitters (1–5 V or 4–20 mA with shunt resistor) connect to the module’s terminal assembly. The module performs A/D conversion, applies engineering unit scaling configured in the TPS database, and passes process values to the controller for closed-loop execution. Redundant IOP configurations are supported for critical loops.
Sourcing & Quality Verification
- All MC-TAIH22 modules supplied by Konmask.com are sourced from verified industrial surplus, authorized distributors, or decommissioned plant inventories with documented service history.

Technical FAQ
Q: Is the MC-TAIH22 compatible with both TPS and TDC 3000 systems?
A: Yes. The module is designed for Honeywell’s IOP architecture used across TPS, TDC 3000, HPM, and APM platforms. Confirm your IOP cage revision for full compatibility.
Q: Can this module accept 4–20 mA inputs directly?
A: The HLAI module is natively configured for 1–5 V inputs. 4–20 mA signals require a 250 Ω shunt resistor at the terminal assembly to convert to voltage. Consult your TPS I/O configuration documentation.
Q: What is the lead time for this module?
A: Lead time depends on current stock levels. Contact Konmask.com directly for real-time availability. In-stock units typically ship within 1–3 business days.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all supplied modules. Extended warranty options are available upon request.
Q: Can you supply the associated terminal assembly or cable?
A: Yes. Associated Honeywell IOP terminal assemblies and field termination accessories can be quoted separately. Please specify your requirements when contacting us.
