EMERSON SPMC1402 – Universal I/O Module | DeltaV Series
Engineering Background
The SPMC1402 is a high-density Universal I/O module engineered by Emerson for deployment within the DeltaV distributed control system (DCS) architecture. Designed to meet the rigorous demands of continuous process industries, this module consolidates multiple signal types into a single, field-proven hardware platform — reducing panel footprint while maximizing signal flexibility.
Product Positioning
Targeted at procurement engineers and automation integrators managing DeltaV-based control systems, the SPMC1402 is the preferred choice for facilities requiring reliable, multi-signal I/O expansion without the overhead of dedicated single-type I/O cards. It is fully compatible with DeltaV S-series and M-series controllers and supports hot-swap replacement for zero-downtime maintenance.

- HART Pass-Through: Full HART 5/6/7 support on every channel enables advanced device diagnostics and asset management via AMS Device Manager.
- Hot-Swap Capability: Replace or insert modules during live operation — critical for high-availability process environments.
- Reduced Spare Parts Inventory: A single SKU covers multiple I/O types, simplifying MRO procurement and warehouse management.
- DeltaV Native Integration: Plug-and-play recognition within DeltaV Explorer — no manual configuration required after insertion.
- Hazardous Area Rated: FM Class I Div 2 and ATEX Zone 2 certifications support deployment in classified areas without additional barriers.
System Architecture & Signal Flow
The SPMC1402 mounts directly onto a DeltaV I/O carrier, which connects to the DeltaV controller via the high-speed I/O bus. Each of the 16 channels is independently configurable in DeltaV Explorer as AI, AO, DI, or DO — with signal type assignment stored in the controller database. Field wiring terminates at the carrier’s marshalling terminals. HART signals are passed transparently to the DeltaV HART multiplexer or directly to AMS for device-level diagnostics. The module draws power from the carrier backplane (24 VDC) and communicates via the proprietary DeltaV I/O bus protocol.

Technical FAQ
Q: Is the SPMC1402 compatible with DeltaV v13 and later?
A: Yes. The SPMC1402 is supported across DeltaV v11 through the current release. Firmware updates may be required for the latest DeltaV versions — contact us for compatibility confirmation.
Q: Can I mix SPMC1402 with legacy single-type I/O cards on the same carrier?
A: No. The SPMC1402 requires a Universal I/O carrier (EIOC-compatible). It cannot be mixed with traditional I/O cards on a standard carrier.
Q: What is the maximum number of SPMC1402 modules per DeltaV controller?
A: This depends on the controller model and I/O bus loading. Refer to the DeltaV Hardware Reference Manual or contact our engineering team for a system sizing review.
Q: Do you provide exchange / repair services?
A: Yes. We offer board-level repair and exchange programs. Contact us with your failed module’s serial number for a repair quote.
Q: Is HART configuration retained after hot-swap?
A: Yes. HART device configuration is stored in the DeltaV controller database, not on the I/O module. Hot-swap replacement restores full functionality automatically.
