Honeywell 51198685-100 | 24VDC Industrial Supply

• Model & Brand: Honeywell 51198685-100, identified in Honeywell documentation as a 20 A Power Supply / Power Module. It is also associated with the SPS5710-2-LF designation in supplier records.
• Application: Honeywell Experion PKS / Universal Process Cabinet power architecture; Honeywell’s current UPC documentation lists 51198685-100 as an ATDI power module, with two modules used in the redundant configuration.
• Physical Dimensions: Approximately 50 × 165 × 342 mm (W × H × D) based on a published packaged/product-size listing. Another supplier reports approximately 55 × 160 × 145 mm, so dimensions should be confirmed against the physical revision before cabinet layout work.
• Estimated Shipping Weight: Plan for approximately 2–3 kg per unit packaged. One supplier lists 2.32 kg, while another lists 2 kg shipping weight.
• What’s in the Box: Power supply module, manufacturer packaging where supplied, and installation documentation if included by the vendor. Do not assume mating connectors or cabinet hardware are included unless specifically listed on the purchase order.

Product Introduction

Power architecture is where this part earns its place in the cabinet. Honeywell 51198685-100 is identified as a 20 A power module used within Honeywell process-control power systems, including the Universal Process Cabinet architecture. In Honeywell’s current UPC documentation, two 51198685-100 modules form the ATDI redundant power-supply arrangement (the chassis/backplate is a separate assembly).

The electrical identity needs to be checked before substitution. Published technical records associate this part with 100–240 VAC input and a 24–26 VDC, 20 A output, while Honeywell documentation identifies it specifically as the 20 A replacement power supply. Do not treat a generic 24 VDC industrial power supply as an automatic replacement; output characteristics, mechanical interface, redundancy behavior, and cabinet certification all matter.

Core Technical Specifications

Honeywell 51198685-100

Honeywell’s UPC installation documentation explicitly lists 51198685-100 (2x) as the ATDI redundant power-module configuration and identifies 51454235-100 as the associated two-PSU chassis.

Be careful with the frequently published 10 A specification. Some third-party listings incorrectly describe 51198685-100 as a 10 A supply, while Honeywell’s own documentation identifies the replacement as a 20 A Power Supply. For asset records, the Honeywell documentation should take precedence.

? Global Compliance & Industry Certifications

For a Honeywell industrial power module of this class, the compliance file should be checked for the certification markings applicable to the specific hardware revision and cabinet configuration.

• CE Mark: Relevant for applicable European-market installations.
• UL/CSA: Industrial-control certification may apply to the equipment/system configuration rather than automatically to every standalone spare.
• RoHS / lead-free status: Some supplier records identify the SPS5710-2-LF designation as a lead-free variant, but verify the physical label and OEM documentation before making a regulatory declaration.
• ATEX / IECEx: Do not assume hazardous-area approval merely because the module is used in a process-control cabinet.
• Marine approvals: DNV GL or other marine certification should only be claimed when the exact product/configuration carries the applicable certificate.

For hazardous-area installations, certification is tied to the complete approved equipment configuration, installation method, and environmental conditions—not simply the presence of a CE mark.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

1. Keep the power module sealed against dust and moisture. Store it in its original packaging or an ESD-safe replacement package, with desiccant where appropriate. Avoid warehouse locations exposed to condensation, washdown mist, or large temperature swings.
2. Protect the AC and DC connection points. The power terminals and mating interfaces should remain covered during storage. Inspect for oxidation, contamination, bent hardware, or damaged insulation before installation.
3. Control the storage environment. A conservative warehouse target is below 60% RH, non-condensing, with stable ambient temperature. Do not stack heavy cartons on the module; the enclosure and terminal areas can be damaged by concentrated mechanical loading.

For long-stored power supplies, visual inspection alone is insufficient. Check the date code, packaging condition, terminal integrity, and insulation condition before putting the unit into a live DCS power system.

Physical Installation Prerequisites

• Install the module only in the specified Honeywell power-supply shelf/chassis. The UPC documentation identifies the ATDI power shelf and associated PSU chassis as the intended mechanical architecture.
• Do not improvise DIN-rail mounting. This is a dedicated cabinet power-system module rather than a general-purpose DIN-rail supply.
• Provide sufficient cabinet clearance for heat dissipation and service access. Use the clearance requirements of the applicable Honeywell cabinet/UPC installation guide rather than relying on the module dimensions alone.
• Confirm protective earth and cabinet bonding before energization.
• Verify AC input wiring, DC output polarity, terminal torque, and redundant-power connections before startup.
• In a redundant configuration, confirm that both modules and the associated power-supply chassis are the correct revision and intended combination.
• Remove power before inserting, removing, or servicing the module.

Honeywell’s UPC documentation specifically identifies the 51198685-100 as part of a dedicated power-supply architecture, so mechanical compatibility should be verified at the shelf/chassis level, not merely by comparing voltage and current ratings.

Buyer’s FAQ

Q: Which HS tariff code should be declared for 51198685-100?
One supplier record lists HS 8504408300, while other suppliers use broader or different classifications. Because tariff treatment depends on the importing country’s tariff schedule and the declared function, use the OEM description—20 A power supply module—and have the customs broker validate the final HS code before shipment.

Q: What Country of Origin should appear on the commercial documents?
Do not assume the COO from a supplier listing. Published records conflict: one supplier states USA, while another lists China. The physical nameplate, OEM documentation, or supplier-issued COO should control the declaration. This is particularly important when preferential tariff treatment is being claimed.

Q: Is shipping insurance worthwhile for this part?
Yes. Although the module is not especially heavy, its replacement value can be significant and the internal power electronics can be damaged by impact or moisture. Use an ESD-safe inner package, mechanical cushioning, and adequate cargo insurance.

Q: Does 51198685-100 include the latest firmware?
No firmware should be expected in the conventional controller-module sense. This is a power supply module, not a C300 controller or processor. Its acceptance inspection should instead focus on part number, hardware revision, electrical ratings, terminal condition, certification markings, and physical integrity.
