HONEYWELL 38001704-100 – Analog Input Module | TDC 3000 / PlantScape DCS Platform
Engineering Background
The HONEYWELL 38001704-100 is a field-proven Analog Input Module designed for integration within Honeywell’s TDC 3000 and PlantScape Distributed Control System (DCS) architectures. Engineered to meet the demanding signal conditioning requirements of continuous process industries, this module provides reliable multi-channel analog signal acquisition with high-resolution conversion and robust noise immunity.
Product Positioning
Targeted at process control engineers and MRO procurement teams managing legacy TDC 3000 / PlantScape installations, the 38001704-100 is the OEM-specified replacement module for analog input functions within the High-Performance Process Manager (HPM) and compatible controller nodes. It eliminates the need for costly system migrations by extending the operational life of existing DCS infrastructure.

- Rapid Commissioning: Plug-and-play backplane interface with automatic module recognition by the HPM controller.
- Broad Signal Compatibility: Supports mA, voltage, thermocouple, and RTD inputs within a single module family.
System Architecture & Signal Flow
The 38001704-100 occupies a standard I/O slot within the TDC 3000 card cage. Field wiring terminates at the associated Field Termination Assembly (FTA), which connects to the module via the I/O Link bus. Analog signals are conditioned, multiplexed, and converted by the onboard A/D circuitry before being transmitted over the backplane to the High-Performance Process Manager (HPM) or compatible controller. The HPM executes configured control strategies using the digitized process values at the defined scan rate. Diagnostic status is reported back to the Universal Control Network (UCN) and is visible in the Honeywell Console or Experion operator station.

Technical FAQ
Q: Is the 38001704-100 compatible with Experion PKS?
A: It is compatible with Experion PKS systems that retain the legacy TDC 3000 I/O bus infrastructure. It is not compatible with Experion’s CIOM-A or Series C I/O architecture.
Q: Can this module accept HART signals?
A: The 38001704-100 is a standard analog input module and does not natively support HART protocol pass-through. HART-capable variants exist within the Honeywell product family — contact us to confirm the correct part number for HART applications.
Q: What FTA is required for this module?
A: The appropriate FTA depends on your signal type and cabinet configuration. Common pairings include the 30731771-001 (standard AI FTA) and 30731772-001 (isolated AI FTA). Confirm with your system documentation or contact Konmask engineering support.
Q: Do you provide a test report?
A: Yes. A functional test report and inspection checklist can be provided upon request, particularly for regulated industries requiring documented traceability.
Q: What is the lead time for bulk orders (>5 units)?
A: Bulk availability is subject to current stock levels. Contact us for a consolidated RFQ — we maintain supplier networks across multiple regions to fulfill larger requirements.
