Product Overview
The Emerson SE4005S2B4 DeltaV S-series Analog Output Plus Card is an analog output module for DeltaV S-series control systems, used to transfer controller-generated analog commands to compatible field equipment. It is suited to control applications where continuous output signals are required rather than simple discrete switching.
In a process control loop, the card receives output commands from the DeltaV controller and transfers them through the I/O and termination path toward the associated field device. Typical equipment includes control valves, positioners, actuators, and other devices that respond to analog control signals.
The Analog Output Plus configuration is suited to DeltaV installations requiring an analog output interface with the functions associated with the Plus version of the S-series I/O platform. It can be used in process plants, utility systems, packaged equipment, and other applications where analog control signals form part of the control strategy.
For maintenance work, the complete signal path should be checked when an output behaves abnormally. Comparing the controller command with the signal at the field termination point helps determine whether the problem is associated with the I/O card, termination path, wiring, configuration, or connected field equipment.

Working Principle
The SE4005S2B4 receives an output command from the DeltaV control strategy and transfers the corresponding analog signal through the S-series I/O and termination path. The connected field device uses this signal to adjust its operating position or output according to the control command.
DeltaV Controller → SE4005S2B4 Analog Output Plus Card → Termination Assembly → Field Device
For a closed-loop process, the controller calculates the required output from process measurements and configured control logic. The SE4005S2B4 then handles the output side of the signal path, allowing the command to reach the associated actuator or control device.
During troubleshooting, checking the commanded output and measuring the actual field-side signal are useful first steps. If the controller command is correct but the expected signal does not reach the field device, the I/O channel, termination assembly, wiring, and field circuit should be examined in sequence.
Role in a DeltaV S-series Control Architecture
The SE4005S2B4 functions as the analog output interface between DeltaV control logic and field equipment. It takes the controller’s calculated output and transfers it into the physical field signal path.
DeltaV Controller → S-series I/O → SE4005S2B4 → Termination → Field Wiring → Control Device

Installation and Maintenance
- Verify that the SE4005S2B4 is compatible with the existing DeltaV S-series configuration.
- Confirm the assigned output channel before connecting field wiring.
- Check the associated termination assembly and terminal assignments.
- Verify that the connected field device accepts the required analog signal.
- Inspect wiring for loose terminals, damaged conductors, or incorrect connections.
- Confirm the controller’s commanded output before investigating the physical signal path.
- Compare the controller value with the actual signal at the field termination.
- Determine whether the abnormal condition affects one channel or multiple channels.
- Check the DeltaV channel and control-strategy configuration when the output command is unexpected.
- Inspect the card and surrounding installation for physical damage or contamination.
- Record existing wiring and configuration before removing a card for replacement.
- After replacement, verify the analog output and field-device response before returning the loop to normal automatic operation.

Technical FAQs
What distinguishes the SE4005S2B4 from a standard analog output card?
The SE4005S2B4 is identified as an Analog Output Plus Card, so replacement selection should be based on the required S-series I/O configuration rather than assuming that every analog output card is interchangeable. The exact DeltaV hardware and channel requirements should be checked before replacement.
What should be measured when an analog actuator does not respond to a DeltaV command?
First verify that the DeltaV controller is generating the expected output value. Then check the output path at the card, termination assembly, and field wiring before examining the actuator or positioner itself.
Why can an analog output problem appear to be a control-strategy fault?
A field device may fail to respond even when the controller is generating the correct command. Wiring problems, termination issues, channel configuration, or an I/O fault can interrupt the physical output path, so the controller command should be compared with the actual field-side signal.
What should be verified before installing an SE4005S2B4 as a replacement?
Check the exact model, DeltaV S-series architecture, I/O configuration, channel assignment, termination arrangement, and field wiring. After installation, verify the output signal and the response of the connected field device before placing the control loop back into automatic service.
