EMERSON SP2402 – Analog Output Module | DeltaV DCS Platform
The EMERSON SP2402 is a precision analog output module engineered for the DeltaV Distributed Control System (DCS) platform. Designed to meet the demanding requirements of continuous process industries, the SP2402 delivers reliable, isolated 4–20 mA analog output signals to field devices including control valves, variable-frequency drives, and positioners. For procurement engineers sourcing verified automation components, the SP2402 represents a proven, OEM-grade solution with full traceability.
Product Positioning: The SP2402 is a channel-isolated analog output card intended for safety-critical and high-availability process control loops. It integrates seamlessly into existing DeltaV I/O subsystems without requiring additional signal conditioning hardware, reducing panel footprint and wiring complexity.

System Architecture & Signal Flow
The SP2402 resides on a DeltaV I/O carrier and communicates with the DeltaV Controller via the proprietary I/O bus. The controller writes a digital setpoint value to the module; the SP2402 converts this to a precision 4–20 mA current signal delivered to the field device. Each channel is independently isolated, ensuring that a wiring fault on one channel does not propagate to adjacent channels. The module reports loop diagnostics (open loop, over-range, under-range) back to the DeltaV operator workstation in real time.
Signal Flow: DeltaV Controller → I/O Bus → SP2402 D/A Converter → Isolated Current Driver → Field Device (Valve / VFD / Positioner)

Technical FAQ
Q: Is the SP2402 compatible with DeltaV S-series controllers?
A: The SP2402 is designed for the DeltaV I/O subsystem. Compatibility with specific controller generations (M-series, S-series) should be verified against your DeltaV system configuration. Contact us for compatibility confirmation.
Q: Can the SP2402 support HART field devices?
A: Yes. The SP2402 supports HART pass-through communication, allowing HART-enabled field devices to be configured and diagnosed via the DeltaV AMS Device Manager.
Q: What is the lead time for the SP2402?
A: In-stock units typically ship within 3–5 business days. For large quantities or urgent requirements, contact us directly for expedited options.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC is available upon request for all shipments. Third-party inspection reports can be arranged for orders above minimum quantity thresholds.
Q: Is the SP2402 RoHS compliant?
A: Please contact us for the current RoHS compliance status of your specific lot. Documentation is provided upon request.
