Product Details

Product Overview

The Emerson DeltaV VE4002S1T1B2 functions as a high-density Discrete Output Module within the DeltaV M-series I/O subsystem. This module provides 8 independent, isolated 24 VDC output channels designed to actuate external field devices such as solenoid valves, motor starters, relays, and indicators. As a critical component of the DeltaV Distributed Control System (DCS), the VE4002S1T1B2 ensures precise command execution and electrical separation between field wiring and the logic backplane. Its hot-swappable design allows for seamless maintenance and system expansion without interrupting plant operations.

Engineering Advantages

Superior Electrical Protection: Each of the 8 channels features full galvanic isolation. This prevents ground loops and protects the DeltaV controller from high-voltage surges or field-side wiring faults, maintaining system uptime in electrically noisy environments.

Intelligent Rotary Keying: The module incorporates a unique mechanical keying system. This prevents maintenance personnel from accidentally inserting the wrong module type into a terminal block, eliminating the risk of mismatched voltage levels damaging field equipment.

Modular Hot-Swappability: The M-series architecture supports "Plug-and-Play" installation. You can remove or replace the VE4002S1T1B2 while the system remains powered, significantly reducing the Mean Time to Repair (MTTR) during critical process runs.

Real-Time Channel Diagnostics: Integrated LED indicators on the module faceplate provide instant visual status for every channel. Operators can immediately identify active outputs or fault conditions without navigating through complex software sub-menus.

High-Density Footprint: The compact 41mm width optimizes rail space in marshalling cabinets. This density allows for more I/O points per linear inch, reducing the overall requirement for large, expensive control enclosures.

FAQs

Q1: Is the Emerson VE4002S1T1B2 a new or refurbished unit?

A1: We provide this module as 100% Brand New and Original Emerson equipment. Every unit arrives in its original factory packaging and includes a full 12-month warranty.

Q2: What is the benefit of channel-to-channel isolation?

A2: Channel-to-channel isolation ensures that an electrical fault or short circuit on one field device (e.g., a solenoid valve) does not impact the other 7 channels on the module. This containment prevents widespread signal loss and simplifies troubleshooting.

Q3: Does this module require an external power supply for the 24 VDC outputs?

A3: Yes. While the module logic draws power from the DeltaV backplane, the field-side 24 VDC power typically originates from an external bulk power supply connected to the DeltaV terminal block.

Q4: Can I replace an older VE4001 or earlier VE4002 variant with this model?

A4: The VE4002S1T1B2 is part of the established M-series Traditional I/O line. It maintains backward compatibility with standard M-series terminal blocks. We recommend verifying your DeltaV software version to ensure the latest hardware definition files are active.
