Product Overview
The Emerson SE4033S2B1 DeltaV S-series Redundant Analog Input Card is an 8-channel redundant analog input solution for DeltaV S-series control systems. It is used to acquire continuous 4–20 mA process signals from field transmitters while maintaining a redundant input path for applications where the loss of a single I/O card could affect process monitoring.
The SE4033S2B1 is intended for HART-capable analog instrumentation and supports both 2-wire and 4-wire transmitter applications. Typical signals come from pressure, temperature, flow, level, and other process transmitters used throughout distributed control systems.
The redundant configuration consists of two analog input cards together with a dedicated redundant 8-channel terminal block. The field signals are therefore presented to the DeltaV system through a paired input arrangement rather than a single card path.
HART communication also makes the module useful for intelligent field-instrument applications where process measurement and instrument information need to be handled through the same analog loop. Correct transmitter wiring, field power, terminal connections, and redundant-card configuration should be verified during commissioning and maintenance.

Working Principle
The SE4033S2B1 receives analog current signals from field transmitters and transfers the measured process information into the DeltaV control system. HART communication can be used alongside the 4–20 mA process signal for compatible intelligent instrumentation.
Field Transmitter → Redundant Terminal Block → SE4033S2B1 Card Pair → DeltaV Controller → Control Logic / HMI / SCADA
The signal path normally operates as follows:
- A compatible transmitter measures a process variable such as pressure, flow, temperature, or level.
- The transmitter represents the measurement using a 4–20 mA current signal.
- The signal enters the redundant terminal-block arrangement and is presented to the paired analog input cards.
- The input circuitry converts the analog current into process data for the DeltaV system.
- DeltaV control logic applies scaling, alarm limits, calculations, or control functions to the acquired value.
- For compatible HART instruments, digital instrument information can be accessed through the HART communication path.
- The measured process value can be displayed on operator stations or passed to supervisory applications.
The redundant architecture allows the input function to be maintained through the paired-card arrangement when an individual card fault occurs, subject to the overall DeltaV redundancy configuration.
Role in a DeltaV S-series Control Architecture
The SE4033S2B1 forms the analog measurement layer between field instrumentation and the DeltaV controller, supplying redundant process measurements for control and supervisory functions.

Installation and Maintenance
- Confirm that the SE4033S2B1 is the correct redundant analog input configuration for the DeltaV system.
- Verify that the associated redundant 8-channel terminal block is installed.
- Confirm the transmitter type and whether each instrument uses a 2-wire or 4-wire connection.
- Check that the field instrument produces a compatible 4–20 mA signal.
- Verify field power and transmitter loop wiring before energizing the input channels.
- Install the paired analog input cards according to the DeltaV S-series redundant I/O arrangement.
- Check terminal assignments carefully because an incorrect field connection can affect both measurement and HART communication.
- Keep analog instrument wiring separated from high-power switching and motor circuits where practical.
- Configure the input range, engineering units, scaling, and alarm limits in the DeltaV engineering environment.
- Compare the controller reading with the transmitter’s expected process value during commissioning.
- Check HART communication separately if the analog measurement is correct but digital instrument information is unavailable.
- If one redundant card reports a fault, inspect its seating, diagnostics, and associated connections while maintaining the healthy redundant path where possible.
- If several channels become abnormal simultaneously, investigate common field power, terminal connections, grounding, and redundant I/O configuration.
- During preventive maintenance, inspect terminal blocks, transmitter loops, card connections, and field wiring for deterioration or loose connections.
Incorrect transmitter configuration, loop wiring, field power problems, scaling errors, and HART communication issues can produce symptoms that resemble an I/O card failure. The complete signal path should be checked before replacing the module.

Technical FAQs
What type of transmitters can be connected to the SE4033S2B1?
The card is intended for compatible 4–20 mA HART transmitters, including both 2-wire and 4-wire field devices. Common applications include pressure, flow, level, and temperature transmitters.
How does HART communication relate to the 4–20 mA signal?
The 4–20 mA loop carries the primary analog process measurement, while HART adds digital communication over the same loop for compatible instruments. This allows the control system to work with the measured process value while also accessing additional instrument information.
Does the redundant configuration provide 16 independent analog inputs?
No. SE4033S2B1 is an 8-channel redundant analog input configuration using two AI cards. The duplicate card arrangement provides redundancy for the input functions rather than creating 16 independently assignable measurement channels.
What should be checked if the analog value is correct but HART communication is unavailable?
Check the transmitter’s HART capability and configuration first, followed by the loop wiring, field power, terminal connections, and DeltaV channel configuration. If the 4–20 mA measurement remains correct while HART data is unavailable, the issue may be related specifically to digital communication rather than the analog input path.
