Product Details

Product Overview

The Emerson VE4054S1C0 functions as the dedicated System Power Supply for the DeltaV M-series Distributed Control System (DCS). This module provides the critical 12 VDC power required by the LocalBus to energize controllers and the associated I/O subsystem. It mounts directly onto the power controller carrier, injecting stable voltage into the internal power bus that spans the length of the I/O interface carriers. By ensuring a consistent power feed across the LocalBus, the VE4054S1C0 enables seamless communication and operation between the CPU and field-connected I/O modules.

Engineering Advantages

Efficient LocalBus Distribution: The VE4054S1C0 supplies 12 VDC directly to the LocalBus, which shares power across the entire controller and I/O subsystem. This centralized power injection eliminates the need for individual power leads to each I/O card, simplifying cabinet wiring.

Support for Redundant Network Architectures: This module works in conjunction with the DeltaV Control Network, supporting dual-speed 10/100BaseT communication. It facilitates the stable power environment necessary for ScTP (Screened Twisted-Pair) Ethernet nodes to operate without signal degradation.

Flexible Mounting Constraints: While maintaining a strict 6.5-meter limit for the total LocalBus length, the VE4054S1C0 supports both horizontal and vertical carrier configurations. This flexibility allows engineers to optimize cabinet space without compromising power integrity.

Enhanced Signal Stability: By providing isolated system power, the module prevents electrical noise from the field-side power (24 VDC) from interfering with the logic-side 12 VDC bus. This separation protects the controller’s CPU from voltage spikes and ripples.

Modular Hot-Swappability: The design permits rapid replacement. Maintenance teams can swap the power module quickly to restore bus power, significantly reducing downtime in mission-critical process environments.

FAQs

Q1: Is the Emerson VE4054S1C0 available as a new unit?

A1: Yes. We supply only 100% Brand New and Original Emerson stock. Each module ships in its original factory packaging and includes a full 12-month warranty.

Q2: Can the LocalBus exceed 6.5 meters if I use high-quality cables?

A2: No. The total length of the LocalBus, including all internal carrier buses and connecting cables, must not exceed 6.5 meters (21.3 ft.). Exceeding this limit results in voltage drops and communication timing errors between the controller and I/O subsystem.

Q3: Does this module provide the 24 VDC power required for field instruments?

A3: No. The VE4054S1C0 provides the 12 VDC System Power for the internal logic of the cards and the controller. You must provide a separate 24 VDC field power supply to the terminal blocks for driving field devices.

Q4: What cable type does the DeltaV Control Network require for this system?

A4: The network requires CAT 5 screened (ScTP) twisted-pair cables to connect nodes to hubs or switches. The shielding is essential to protect the 10/100BaseT communication from industrial electromagnetic interference.
