Product Details

38001704-100 Product Description

The Honeywell 38001704-100 is a precision Analog Input Module engineered for the TDC 3000 Distributed Control System (DCS) platform, delivering reliable 4–20 mA signal acquisition and seamless integration across the full spectrum of smart factory data infrastructure. Designed to serve as a critical node in the industrial data chain, this module bridges field-level instrumentation — including pressure transmitters, temperature sensors, flow meters, and level detectors — with the supervisory control and data acquisition (SCADA) layer, enabling real-time process visibility, remote diagnostics, and continuous operational transparency across complex manufacturing environments.

In modern smart factory architectures, the integrity of analog signal acquisition is foundational. The 38001704-100 captures process variables at the field device level and transmits structured data upward through the TDC 3000 backplane bus to the High-Level Manager (HLM) and Application Module (AM), where data is processed, historized, and made available to operator consoles and SCADA workstations. This unbroken data pathway — from sensor to control room — is what enables plant-wide transparency, predictive maintenance, and closed-loop process optimization.

The 38001704-100 Analog Input Module occupies a pivotal position in the TDC 3000 data flow architecture. At the field level, process instruments — such as Honeywell ST 3000 Smart Transmitters, thermocouple assemblies, and differential pressure sensors — generate continuous analog signals that the 38001704-100 digitizes and forwards via the TDC 3000 backplane to the Process Manager (PM) or Advanced Process Manager (APM). These controllers execute regulatory and advanced control strategies, passing setpoints and alarm states to the Honeywell Universal Station (US) operator console for real-time HMI visualization.

Upstream, the Local Control Network (LCN) carries structured process data to the Honeywell History Module (HM), where time-stamped process records are stored for trend analysis, compliance reporting, and performance benchmarking. The Application Module (AM) runs advanced calculations — including model predictive control (MPC) and optimization routines — drawing on the analog inputs delivered by modules like the 38001704-100 to generate actionable control outputs.

For facilities integrating legacy TDC 3000 infrastructure with modern Industrial IoT (IIoT) platforms, the data chain extends further: a Honeywell Experion PKS gateway or a third-party OPC-UA edge gateway can bridge LCN data to cloud-based SCADA dashboards, enabling remote diagnostics, KPI monitoring, and predictive maintenance alerts accessible from any networked device. In this architecture, the 38001704-100 remains the originating data source — the module that converts physical process reality into the digital signals that drive plant-wide intelligence.

Complementary components in this data chain include the Honeywell 38001705-100 Analog Output Module for closed-loop control signal delivery, the 51304485-100 Power Supply Module ensuring stable backplane power, the 51401469-200 Communication Interface Module for UCN connectivity, and the 51196682-100 File Module for configuration storage. Together, these components form a complete, validated TDC 3000 I/O subsystem capable of supporting continuous process industries including refining, petrochemicals, power generation, and specialty chemicals manufacturing.

Many industrial facilities operating TDC 3000 platforms face persistent challenges: aging analog input modules that introduce signal drift, protocol fragmentation between legacy DCS infrastructure and modern SCADA or MES systems, and limited remote visibility into field device health. The Honeywell 38001704-100 directly addresses these pain points by providing a factory-tested, specification-compliant replacement that restores signal integrity and eliminates data gaps at the I/O layer.

Protocol fragmentation — where field devices speak 4–20 mA analog while upper-layer systems expect digital Modbus, HART, or OPC-UA data — is resolved through the TDC 3000 architecture's built-in protocol translation stack. The 38001704-100 feeds clean analog data into the Process Manager, which normalizes and exposes it via the LCN to any connected gateway or historian. This eliminates data islands and ensures that every field measurement is visible, logged, and actionable at the SCADA and MES levels.

Remote diagnostics capability is enhanced when the 38001704-100 is paired with Honeywell's Experion PKS or a compatible OPC-DA/OPC-UA server, allowing maintenance engineers to monitor channel health, signal range violations, and module status from remote workstations — reducing unplanned downtime and enabling condition-based maintenance strategies. Alarm tracking and event logging are fully supported through the TDC 3000 alarm management framework, ensuring that every process excursion captured by the analog input is timestamped, categorized, and routed to the appropriate operator or maintenance workflow.

For facilities planning system expansion, the modular TDC 3000 architecture allows additional 38001704-100 modules to be added to existing I/O racks without disrupting live process control — supporting phased capacity growth aligned with production scale-up requirements.

Q1: What communication protocols does the Honeywell 38001704-100 support, and how does it integrate with modern SCADA systems? The 38001704-100 operates on the TDC 3000 backplane bus, accepting 4–20 mA analog field signals and transmitting digitized process data via the Local Control Network (LCN) and Universal Control Network (UCN). Integration with modern SCADA platforms is achieved through Honeywell Experion PKS gateways or OPC-UA/OPC-DA servers, which bridge TDC 3000 data to contemporary supervisory systems without requiring field rewiring.

Q2: How is network stability and signal reliability ensured for this analog input module? Each 38001704-100 unit supplied by NANKMOS undergoes pre-shipment functional testing to verify channel accuracy, signal range compliance, and backplane communication integrity. The TDC 3000 platform's redundant LCN architecture further ensures that analog input data reaches the control layer without interruption, even during network segment maintenance or switchover events.

Q3: Can the 38001704-100 support remote diagnostics and predictive maintenance workflows? Yes. When integrated within a TDC 3000 system connected to Honeywell Experion PKS or a compatible OPC server, the 38001704-100's channel data — including signal levels, range violations, and module status — is accessible to remote diagnostic tools. This enables maintenance teams to identify degrading sensors, wiring faults, or module anomalies before they escalate to process upsets, supporting condition-based and predictive maintenance programs.

Q4: What warranty and support terms apply to this module? All Honeywell 38001704-100 modules supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment. Units are pre-shipment tested, verified against OEM specifications, and shipped with full traceability documentation. In-stock availability ensures rapid dispatch to minimize plant downtime.
