Product Overview
The Emerson VE5109 DeltaV M-Series DC to DC System Power Supply supplies regulated DC power to DeltaV M-Series controllers and I/O interfaces. It accepts 12 V DC or 24 V DC input power and generates the voltage rails required by the control system electronics. Within a distributed control system (DCS), this module supports the power infrastructure needed for process monitoring, controller operation, and I/O signal handling.
The VE5109 is installed in a compatible DeltaV power/controller carrier rather than functioning as a standalone power converter. The carrier provides internal power buses for the controller and I/O interfaces, reducing the need for separate external power wiring between these components. This arrangement is useful when building new control cabinets, maintaining existing M-Series installations, or expanding a process control system.
The module provides a 12 V DC output for I/O interface power and supplies the 5 V DC and 3.3 V DC rails required by the controller electronics. When supplied from a 24 V DC bulk power source, the enhanced M-Series DC/DC power supply supports up to 8.0 A on the 12 V DC I/O interface power bus within its specified operating conditions. The available output capacity must be evaluated against the actual controller, I/O carrier, and module load.
For maintenance and system upgrades, the VE5109 supports modular installation and power-system expansion. Its input compatibility allows integration with suitable 12 V DC or 24 V DC plant power arrangements, while power-status indication and relay alarm contacts help technicians identify supply-related problems. Correct carrier selection, load calculations, input wiring, and redundancy planning remain essential to maintaining the intended system availability.

Working Principle
The Emerson VE5109 converts incoming DC power into the voltage rails required by DeltaV M-Series control hardware. Its internal conversion and regulation circuitry maintains the specified outputs within the operating limits of the supply.
12 V DC or 24 V DC Bulk Power → VE5109 DC/DC Conversion and Regulation → 12 V DC I/O Power + 5 V DC and 3.3 V DC Controller Power → DeltaV M-Series Hardware
When the input is 12 V DC, the available 12 V DC output current differs from the rating available with a 24 V DC input. The supply can deliver up to 13 A on the 12 V DC output at temperatures from -40 to 60°C with a 12 V DC input. With a 24 V DC input, the corresponding rating is up to 8.0 A under the same temperature conditions. The available current decreases at higher operating temperatures, so system load calculations must use the rating applicable to the actual input voltage and ambient temperature.
The controller’s 5 V DC and 3.3 V DC rails support the electronic circuitry required for controller operation. Their combined output power is limited to 10 W, even though each rail has an individual current rating of 2.0 A. The 12 V DC output supports the I/O interface power bus within the limits of the installed carrier and system configuration.
The module also monitors specified output conditions. When the 5 V DC and 3.3 V DC outputs fall outside their permitted tolerances, the red error indicator provides a local indication and the alarm relay changes state. This helps maintenance personnel distinguish a power-supply problem from certain faults originating in controller or I/O hardware.
If the incoming bulk power fails, the supply’s hold-up characteristics and fault-detection provisions affect the system response. The VE5109 is therefore one element of the overall power architecture; uninterrupted operation depends on the input source, supply configuration, redundancy arrangement, connected load, and the requirements of the installed DeltaV system.
Role in a DeltaV M-Series Control Architecture
The VE5109 occupies the system-power layer of a DeltaV M-Series installation. It converts plant DC power into the regulated voltages required by the controller and I/O interface hardware, with power distributed through the compatible carrier’s internal buses.
Plant DC Power Source → VE5109 System Power Supply → Power/Controller Carrier → DeltaV Controller and I/O Interfaces → Process Control and Monitoring

Technical FAQs
What Is the Emerson VE5109 DeltaV M-Series DC to DC System Power Supply Used For?
The VE5109 supplies regulated DC power to DeltaV M-Series controllers and I/O interfaces. It accepts 12 V DC or 24 V DC input power and provides 12 V DC for I/O interface power along with 5 V DC and 3.3 V DC for controller electronics. It installs in a compatible DeltaV power/controller carrier.
What Is the Difference Between the VE5109’s 12 V DC and 24 V DC Input Configurations?
The VE5109 supports both nominal input voltages, but the available 12 V DC output current depends on the input voltage and operating temperature. At -40 to 60°C, the specified 12 V DC output rating is up to 13 A with a 12 V DC input and up to 8.0 A with a 24 V DC input. Engineers should use the applicable rating when calculating system power requirements.
Can the VE5109 Be Used as a Direct Replacement for Another DeltaV M-Series Power Supply?
Replacement suitability depends on the original model, input voltage, output requirements, carrier configuration, and system certifications. The VE5109 is the non-marine-certified model listed for the M-Series DC-to-DC system power supply. A related model, such as the VE5009, has marine certification; the two should not be treated as interchangeable for every installation without confirming the applicable system requirements.
What Do the Green and Red LEDs on the VE5109 Indicate?
The green LED indicates that DC input power is applied and the internal fuse/diode is functioning. The red error LED indicates that the 5 V DC and 3.3 V DC outputs are outside their specified tolerances. If the red LED is illuminated, technicians should check the input supply, output conditions, connected load, and relevant wiring before determining whether the power supply needs replacement.
