Description
Product Overview
The Emerson SE4005S2B1 is designed for continuous control applications in which the DeltaV system must send an adjustable analog command to a field device. Its eight 4–20 mA output channels can support applications such as modulating control valves, compatible valve positioners, and other current-driven equipment. HART support enables digital communication with compatible smart field devices, subject to the instrument, loop wiring, and configured system implementation. The assembly is identified in Emerson’s S-series Traditional I/O documentation as an analog output card with a standard 8-channel terminal block.
In practical operation, an incorrect output signal can affect valve position, actuator response, or other control actions. Troubleshooting should distinguish a failed output channel from field wiring faults, load problems, incorrect controller configuration, or a defective actuator. Before replacing the Emerson SE4005S2B1, verify the full part number, terminal-block arrangement, output-loop requirements, and installed DeltaV hardware configuration.
The SE4005S2B1 should not be confused with an analog input card, which measures field signals rather than generating them. Its terminal-block suffix also matters: the B2 version uses a fused 8-channel terminal block, while the B3 version uses a 16-pin mass terminal block. Confirm the complete assembly required by the existing installation. For used or refurbished stock, request documented output-channel testing and confirmation of the unit’s condition before installation.
Product Introduction
A control valve that fails to follow its requested position may have an actuator problem, a wiring fault, or an issue with the analog output path. The SE4005S2B1 provides eight 4–20 mA HART output channels for compatible field control devices in a DeltaV S-series installation.
Check the installed terminal block and loop requirements before ordering. A card that matches the output signal but not the termination arrangement may not be suitable for the existing cabinet.

Frequently Asked Questions
1. Can I hot-swap the Emerson SE4005S2B1?
Do not assume live removal is permitted in every installation. Follow the applicable DeltaV hardware instructions and plant maintenance procedure. Determine whether the affected control outputs can be safely maintained during replacement, and assess the consequences for connected actuators.
2. Does the support firmware v3.1?
A standalone firmware v3.1 requirement is not established for this analog output assembly. Check the DeltaV controller, system software, and hardware compatibility requirements separately.
3. Does the support 4–20 mA HART output?
Yes. Emerson’s S-series product data identifies the as an eight-channel 4–20 mA HART analog output card with a standard terminal block. HART operation depends on compatible field instrumentation and the configured loop.
4. Can I use the to read a transmitter signal?
No. It is an analog output assembly designed to generate current commands. For reading a 4–20 mA transmitter, select a compatible analog input card, such as the SE4003S2B1, after checking the required configuration.
5. Is the interchangeable with the SE4005S2B2?
Not without reviewing the termination requirements. The uses a standard 8-channel terminal block, whereas the SE4005S2B2 uses a fused 8-channel terminal block. Confirm the wiring and approved hardware configuration before substitution.
6. How should I test a replacement analog output card?
Verify the module identification and terminal condition, then request documented functional testing. During commissioning, check each configured output against the commanded value using an approved test method, and confirm the connected field device responds correctly.
7. What should I verify before ordering a used or refurbished ?
Confirm the exact part number, included terminal block, physical condition, output-channel test results, HART test scope where applicable, warranty, and return terms. Also check the existing carrier and loop requirements to avoid installing an electrically or mechanically incompatible assembly.
