Emerson SP3402 – Universal Input Module | DeltaV DCS Platform
Engineering Background
The Emerson SP3402 is a high-density universal input module engineered for the Emerson DeltaV Distributed Control System (DCS). Designed to accept a wide range of field signal types on a per-channel basis, the SP3402 eliminates the need for dedicated signal-type cards, dramatically reducing panel footprint and spare-parts inventory in process-critical installations.
Product Positioning
Targeted at instrumentation and control engineers in oil & gas, chemical processing, power generation, and pharmaceutical manufacturing, the SP3402 delivers the flexibility of a universal analog front-end with the reliability demanded by SIL-rated and continuous-process environments. It integrates natively into the DeltaV I/O subsystem without additional signal conditioning hardware.

Proven Application Environments
- Oil & Gas: Wellhead temperature and pressure monitoring with HART-enabled transmitters
- Chemical Processing: Multi-point RTD profiling in reactor vessels
- Power Generation: Thermocouple-based turbine exhaust temperature scanning
- Pharmaceutical: FDA 21 CFR Part 11-compliant batch process data acquisition
- Pulp & Paper: Mixed-signal I/O consolidation in distributed field junction boxes
Engineering Advantages
- True Universal Input: Each channel independently configured in DeltaV Explorer — no hardware jumpers or range cards required
- HART Transparency: Full HART variable pass-through enables AMS Device Manager integration for predictive maintenance
- Hot-Swap Capability: Module replacement without process shutdown; DeltaV automatically re-downloads configuration
- Reduced BOM Complexity: One SKU replaces TC-only, RTD-only, and mA-only cards — simplifies spare-parts strategy
- High-Density I/O: 8 universal channels per slot maximizes cabinet utilization
- Integrated Diagnostics: Open-wire, out-of-range, and sensor-failure alarms reported natively to DeltaV operator station
System Architecture & Signal Flow
The SP3402 mounts on a DeltaV S-Series I/O carrier and communicates with the DeltaV Controller via the high-speed I/O bus. Field wiring terminates at the carrier’s marshalling terminals. Each channel’s signal type is software-defined in DeltaV Explorer; the module’s internal multiplexer and 16-bit sigma-delta ADC convert the selected signal to a digital value, which is passed to the controller scan engine at the configured update rate. HART primary and secondary variables are extracted and forwarded to AMS Device Manager over the same physical wiring.

Technical FAQ
Q: Is the SP3402 compatible with DeltaV Version 14.x and later?
A: Yes. The SP3402 is supported across DeltaV v11 through the current release. Firmware updates are managed via DeltaV Explorer.
Q: Can I mix TC and mA channels on the same module?
A: Yes. Each of the 8 channels is independently configured — you can assign any supported signal type to any channel without hardware changes.
Q: Does the module support HART 7?
A: Yes. The SP3402 supports both HART 5 and HART 7 devices, with full variable pass-through to AMS Device Manager.
Q: What is the lead time for in-stock units?
A: In-stock units typically ship within 1–2 business days. Contact us to confirm current availability.
Q: Can I return a module if it does not meet our acceptance criteria?
A: Yes. We offer a 30-day return policy for unused modules in original condition. Please contact [email protected] to initiate an RMA.
