Emerson VE5008 DeltaV DC/DC Power Supply Module

The Emerson VE5008, also cataloged as the VE5008 Power Supply Module, operates as a dedicated hardware component for direct power conditioning and rail distribution within DeltaV Distributed Control System platforms. This DC-to-DC conversion assembly converts 24 VDC or 12 VDC input sources into regulated internal voltage levels to energize system backplanes and carrier-mounted control electronics.

Hardware Specifications

Cold Junction Compensation & Loop Isolation

The Emerson VE5008 incorporates internal channel-to-channel isolation and galvanic separation barriers to insulate backplane control buses from field power surges. By maintaining stable secondary DC voltage outputs across fluctuating primary input loads, the unit preserves signal integrity for connected 4-20 mA HART loop protocol field instruments and temperature input modules requiring cold junction compensation (CJC) accuracy.

Frequently Asked Questions

Q: What are the input electrical specifications for the VE5008 power supply module?

A: The module accepts DC to DC power inputs operating at 24 VDC drawing 6.1 A, or 12 VDC drawing 14.8 A.

Q: How is the VE5008 module installed onto the DeltaV system structure?

A: It mounts directly into standard horizontal or vertical power supply carrier slots, engaging rear bus connectors without external cabling.

Field Installation Guidelines

1. Turn off all primary DC feed breakers before seating the module into the carrier slot.
2. Align the module card guides with the targeted power carrier slot and slide the unit in firmly until the backplane connectors fully lock.
3. Verify that the incoming primary supply matches specified voltage and current thresholds (24 VDC at 6.1 A or 12 VDC at 14.8 A).
4. Fasten the front retention screws to secure the module against vibration and ensure continuous earth ground bonding.
5. Route primary DC input wiring through designated cabinet wire ducts away from high-voltage AC lines to prevent inductive coupling.
