Why Engineers Specify This Model
- Universal Channel Flexibility: Each of the 16 channels can be independently configured as digital input or output — eliminating the need for separate DI and DO modules and reducing spare-parts inventory.
- Hot-Swap Capability: Supports online insertion and removal without process interruption, critical for high-availability continuous process plants.
- Native DeltaV Integration: Plug-and-play on DeltaV carriers with automatic module recognition; no manual addressing required.
- Robust Isolation: Optical isolation on every channel protects the controller backplane from field-side transients and ground loops.
- Diagnostics & HART Pass-Through: Built-in channel-level diagnostics surface faults directly in DeltaV Explorer for rapid troubleshooting.
- Proven Field Record: Widely deployed across Emerson’s global installed base in refining, LNG, and specialty chemical sectors.

Application-Specific FAQ
Q: Can the SPMD1402 replace an older EMERSON MD Plus digital I/O module in an existing DeltaV system?
A: Yes, the SPMD1402 is backward-compatible with DeltaV v10.3 and later. Verify your DeltaV system version and carrier slot type before installation.
Q: Is the SPMD1402 suitable for SIL 2 safety loops?
A: The module can participate in SIL 2 safety instrumented functions when used with a certified DeltaV SIS controller and appropriate safety logic. Consult Emerson’s SIL data sheet (document D800001X012) for PFD values.
Q: What is the maximum cable length for field wiring to the SPMD1402?
A: Emerson recommends a maximum of 300 m (1,000 ft) for 24 VDC digital signals using 0.5 mm² (20 AWG) shielded twisted-pair cable. Longer runs require voltage drop calculations.
Q: Does the module support NAMUR-level sensors (IEC 60947-5-6)?
A: The SPMD1402 is designed for standard 24 VDC discrete signals. For NAMUR proximity sensors, an external NAMUR signal conditioner/barrier is required before the module input.
Q: Can I mix input and output channels within the same module?
A: Yes. Each channel is independently configurable as DI or DO via DeltaV Explorer software — no hardware jumpers required.
