Product Details

MC-TAIH02 51304453-150 Product Description

The Honeywell MC-TAIH02 51304453-150 is an 8-channel HART-enabled analog input module engineered for the Experion PKS C300 Controller platform. In smart factory environments where real-time field data is the backbone of process control, this module serves as a critical node in the industrial data chain — bridging physical sensors, transmitters, and field instruments with the DCS control layer, SCADA systems, and plant-wide data visualization platforms.

Deployed across refining, chemical processing, power generation, and advanced manufacturing sites, the MC-TAIH02 captures 4–20 mA analog signals from pressure transmitters, temperature sensors, flow meters, and level instruments, converting them into structured digital data streams that feed directly into the Honeywell Experion PKS environment. This seamless signal acquisition forms the foundation of a connected factory data architecture — enabling operators to monitor, analyze, and act on process variables with sub-second latency.

In a fully integrated smart factory, the MC-TAIH02 sits at the signal acquisition layer — the first point where physical process data enters the digital control network. Field instruments such as Honeywell STT850 Smart Temperature Transmitters and STG800 Series Smart Pressure Transmitters output 4–20 mA HART signals that are captured by the MC-TAIH02 across its 8 isolated input channels. These signals are conditioned, digitized, and passed via the C300 I/O Link backplane to the Honeywell C300 Controller, which executes control logic and forwards process data upstream.

From the C300 Controller, real-time process values are transmitted over the Fault-Tolerant Ethernet (FTE) network — Honeywell's redundant, deterministic plant network — to the Experion PKS server. Operators at Experion Station HMI workstations gain live visibility into all 8 analog channels, with configurable alarm thresholds, trend displays, and historical logging. For sites running Honeywell's Field Device Manager (FDM) or Emerson AMS Device Manager, the HART secondary channel of the MC-TAIH02 enables remote device diagnostics — reading device health, calibration status, and loop integrity without interrupting the primary 4–20 mA control signal.

At the SCADA integration layer, the Experion PKS OPC DA/UA server publishes live tag values from the MC-TAIH02 channels to third-party SCADA platforms, MES systems, and data historians such as OSIsoft PI or Honeywell Uniformance PHD. This enables plant-wide data aggregation, KPI dashboards, and predictive maintenance analytics. For remote sites or multi-plant architectures, Honeywell's LEAP (Lean Automation Project) topology allows the C300 and its associated MC-TAIH02 I/O modules to be distributed across the plant floor, reducing marshalling cabinet complexity while maintaining full network connectivity.

In multi-vendor automation environments, the MC-TAIH02 can coexist with Siemens ET 200SP remote I/O, Rockwell Automation 1756-IF16 ControlLogix analog input modules, and Yokogawa CENTUM VP I/O cards — each feeding their respective controllers while sharing process data at the SCADA or MES level via OPC-UA or Modbus TCP gateways. Edge computing nodes, such as Honeywell's Connected Plant solutions or third-party IIoT gateways, can subscribe to HART device data from the MC-TAIH02 for local analytics, anomaly detection, and cloud forwarding to platforms like Honeywell Forge or Azure IoT Hub.

Many industrial sites face persistent data gaps: field instruments that speak HART but whose secondary diagnostic channel is never read, analog signals that are acquired but never contextualized, and DCS I/O modules that operate in isolation from the broader plant data network. The MC-TAIH02 addresses these challenges directly.

Protocol Fragmentation: Sites running mixed HART and non-HART field devices often struggle with inconsistent diagnostic coverage. The MC-TAIH02's native HART support ensures that all 8 connected field devices can be interrogated for device health, loop diagnostics, and calibration data — eliminating the need for separate HART multiplexers or handheld communicators for routine checks.

Data Silos: When analog input data remains trapped in the DCS and never reaches the SCADA or MES layer, production teams lose visibility into process trends and equipment health. By integrating the MC-TAIH02 within the Experion PKS architecture, all channel data is automatically available to OPC clients, data historians, and reporting tools — breaking down the silos between the control layer and the information layer.

Remote Monitoring Gaps: For unmanned or remote process units, the ability to perform remote diagnostics without dispatching field technicians is critical. The MC-TAIH02's HART pass-through capability, combined with Honeywell FDM, enables remote loop checks, device configuration, and predictive maintenance scheduling from the control room or from a remote operations center.

Production Line Transparency: Real-time analog data from the MC-TAIH02 feeds directly into Experion PKS trend displays and alarm management systems, giving operators immediate visibility into process deviations, enabling faster alarm response, and supporting root cause analysis with time-stamped historical data.

System Scalability: As production capacity expands, additional MC-TAIH02 modules can be added to the C300 I/O chassis without controller replacement, supporting incremental plant expansion while preserving the existing network architecture and SCADA tag structure.

Q1: Does the MC-TAIH02 support HART communication on all 8 channels simultaneously?Yes. The MC-TAIH02 supports HART protocol on all 8 analog input channels concurrently. Each channel can independently communicate with its connected HART-enabled field device for remote diagnostics, device configuration, and status monitoring — without interrupting the primary 4–20 mA process signal.

Q2: What is the network latency for analog data transmission from the MC-TAIH02 to the Experion PKS server?Within the Experion PKS architecture, the MC-TAIH02 transmits analog data via the C300 I/O Link backplane to the C300 Controller, which then forwards process values over the Fault-Tolerant Ethernet (FTE) network. Typical scan cycle times are configurable from 100 ms to 1 second, supporting real-time process monitoring with deterministic, low-latency data delivery.

Q3: Can the MC-TAIH02 be integrated with third-party SCADA systems outside of Experion PKS?Yes. Process data acquired by the MC-TAIH02 is published by the Experion PKS server via OPC DA and OPC UA interfaces, making it accessible to any OPC-compliant SCADA platform, MES system, or data historian. This enables seamless integration with Wonderware, iFIX, Ignition SCADA, OSIsoft PI, and other third-party systems without additional hardware.

Q4: What warranty and pre-shipment testing does the MC-TAIH02 carry?Every MC-TAIH02 51304453-150 unit supplied by NANKMOS is covered by a 12-month warranty and undergoes pre-shipment functional testing to verify channel integrity, HART communication, and backplane connectivity. In-stock units are available for immediate dispatch to support urgent project timelines and unplanned maintenance requirements.
