Emerson ES0350.M1A05L.27N0 Replacement for DeltaV Series

Product Overview

Emerson ES0350.M1A05L.27N0 Replacement for DeltaV Series: Smooth Migration & Legacy System Upgrade

The Emerson ES0350.M1A05L.27N0 is an 8-channel HART-enabled 4–20 mA analog output module designed for the DeltaV distributed control system platform. As Emerson continues to evolve its DeltaV product line, many facilities operating legacy DeltaV S-series or M-series controllers are facing end-of-life notices on modules such as the ES0350.M1A05L.27N0. TOPNLMS supplies verified replacement and upgrade units to support seamless migration with minimal process disruption.

Whether your plant is transitioning from an older DeltaV MD Plus controller to a newer DeltaV MX or SX architecture, or simply replacing a failed output module in an existing rack, this unit is sourced, tested, and shipped ready for installation. Our procurement team specializes in hard-to-find DeltaV I/O modules, and we maintain stock of both current-production and legacy-compatible units to support your retrofit timeline.

Seamless Upgrade Solutions

A successful DeltaV output module migration rarely involves a single component. When replacing the ES0350.M1A05L.27N0, field engineers typically review the surrounding I/O infrastructure to ensure system-wide compatibility. In most retrofit projects, the DeltaV I/O carrier or terminal block assembly is inspected alongside the output module swap — units such as the DeltaV 8-wide I/O carrier (VE4001S2T1B2) are commonly evaluated for condition and replaced if corrosion or connector wear is detected.

For plants upgrading from non-HART analog output to full HART communication, the addition of a HART multiplexer or HART-capable asset management interface (such as those integrated into the DeltaV Asset Management Solution) is often part of the same project scope. This allows the new HART capability of the ES0350.M1A05L.27N0 to be fully utilized for valve diagnostics and field device health monitoring without additional wiring changes.

On the controller side, facilities migrating from DeltaV MD Plus controllers to DeltaV MX controllers will also assess their DeltaV power supplies (PS1 or PS2 series) and redundant power conditioners to confirm adequate current capacity for the expanded I/O count. Analog input modules such as the Emerson VE3008 or ES0350-series AI cards are frequently replaced in the same maintenance window to standardize the I/O generation across the cabinet.

Communication infrastructure is another key consideration. If the migration involves upgrading from a legacy DeltaV workstation running DeltaV v11 to a newer DeltaV v14 or v15 environment, the DeltaV controller firmware and I/O module firmware must be aligned. In some cases, a DeltaV CIOC (Controller I/O Card) or EIOC (Ethernet I/O Card) is introduced to support remote I/O over Ethernet/IP, which changes the backplane architecture but retains field wiring compatibility.

For control cabinet space planning, DeltaV vertical carriers and horizontal mounting rails are assessed to confirm that the replacement ES0350.M1A05L.27N0 fits within the existing DIN-rail or panel-mount enclosure without requiring cabinet expansion. Signal isolators or loop-powered barriers may also be reviewed if intrinsic safety (IS) zones are involved in the output loop.

Retrofit Guidance FAQ

Q: Can I replace the ES0350.M1A05L.27N0 without modifying field wiring?
A: Yes. The ES0350.M1A05L.27N0 uses the standard DeltaV I/O carrier terminal interface. Existing 4–20 mA field wiring connects to the same terminal block positions. No rewiring is required for a direct slot replacement.

Q: Do I need to re-download the DeltaV control strategy after replacing this module?
A: In most cases, a module replacement at the same slot address does not require a full strategy download. The DeltaV controller will recognize the new module during the next scan cycle. However, if the module firmware version differs significantly, a partial download or module commission step may be required via DeltaV Explorer.

Q: Is HART communication automatically enabled after installation?
A: HART capability is hardware-enabled on the ES0350.M1A05L.27N0. To utilize HART pass-through for field device diagnostics, the corresponding HART parameter must be enabled in the DeltaV module configuration within DeltaV Control Studio. No additional hardware is needed.

Q: What if my existing DeltaV carrier is an older generation?
A: The ES0350.M1A05L.27N0 is compatible with standard DeltaV I/O carriers. If your carrier is a first-generation 2-wide or 4-wide unit, physical fitment should be verified against the carrier part number before installation. TOPNLMS can assist with carrier compatibility checks prior to shipment.

Q: Can this module be used in a redundant I/O configuration?
A: The ES0350.M1A05L.27N0 supports DeltaV standard (non-redundant) I/O architecture. For redundant analog output requirements, a different DeltaV module series with redundancy support would be required. Please contact our technical team for guidance on redundant output module alternatives.

Q: What communication protocols does this module support beyond HART?
A: The module communicates with the DeltaV controller via the proprietary DeltaV backplane bus. HART is the field-side protocol for communicating with smart field devices. FOUNDATION Fieldbus or PROFIBUS output would require a different module type.
