Description
The Emerson KJ4110X1-EA1 12P1878X032 is an intrinsically safe (IS) system power supply module engineered for the Emerson DeltaV distributed control system (DCS). It converts a wide-range DC input of 18.5 to 36 VDC into a regulated 12 VDC output at 5 A, delivering 60 W of continuous power to DeltaV system components. This wide input range accommodates industrial battery systems, 24 VDC control buses, and other DC power sources commonly found in process automation environments.
The module is specifically designated as an intrinsically safe power supply, indicating its suitability for applications where the connected circuits must not release sufficient energy to ignite hazardous atmospheres. This makes it appropriate for installation in Zone 2 and Division 2 hazardous locations when integrated with appropriate IS barriers and properly certified field devices. The IS designation ensures that the power supply maintains energy limitation characteristics required for intrinsically safe circuit powering.

Features:
- Fisher-Rosemount Systems
- Intrinsically Safe (IS) System Power Supply
- Supports controllers and I/O subsystems
- Integrated protection circuitry
Designed for industrial environments requiring high system availability, the power supply continuously converts incoming power into the regulated voltage levels required by DeltaV hardware. Integrated protection mechanisms help safeguard connected equipment against electrical faults such as overloads and short circuits, while built-in diagnostic capabilities allow maintenance personnel to monitor power supply status and identify potential issues.
The KJ4110X1-EA1 12P1878X032 Emerson Power Supply Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The module's high-efficiency design minimizes energy loss and heat generation, contributing to long-term reliability and reduced thermal stress on adjacent components. Overcurrent protection is built into the unit, preventing equipment damage in the event of output short circuits or excessive load conditions. The wide input voltage range of 18.5 to 36 VDC provides flexibility in power system architecture, allowing the same module to operate from 24 VDC nominal systems with significant voltage tolerance for battery discharge conditions or long cable runs.
- Chemical Process Control:Clean power for reactors, temp/pressure/level
- Oil & Gas Exploration & Transport:Uptime for wellhead/pipeline safety
- Refineries & Petrochemical Processing:Baseline power for cracking/distillation/blending
- Power & Energy Utilities:Boiler/turbine: emissions & loop power
- Pharmaceutical and Life Sciences:Spark-free, consistent power for batch reactors
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Maintain Wiring Separation: Run all Intrinsically Safe field wiring completely separate from Non-IS power cables. Ensure a minimum physical clearance barrier of 50 mm (2 inches) inside the cabinet, or use grounded metal conduits to prevent cross-cable voltage induction.
Enclosure Rating: Mount the carrier inside an approved, dust-tight, weatherproof industrial enclosure. For deployments located in active Zone 2 or Class I Division 2 spaces, the enclosure must carry at least an IP54 or NEMA 4 safety rating.
Technical notes
The KJ4110X1-EA1 mounts within the DeltaV system architecture using dedicated power supply carriers such as the KJ4101X1-BC1 (VE5010) or the KJ4101X1-BA1 IS 8-wide carrier. These carriers integrate power distribution directly into the backplane, eliminating the need for external power wiring between modules and reducing installation complexity. The integrated shield ground bar isolates and drains field noise away from system power, improving signal integrity in electrically noisy industrial environments.
