Emerson VE4002S1T2B5
Product Introduction
Field actuators and indicator lights demand reliable switching logic that won’t fail mid-process. The Emerson is a 32-channel discrete output card engineered for the DeltaV Series 2 Plus platform. It provides isolated relay contacts to safely switch 24V DC field loads based on controller logic.
This unit delivers consistent switching performance across all 32 channels with built-in diagnostics. Real-world deployments show that using the exact Series 2 Plus terminal block specification prevents backplane communication errors and ensures accurate feedback to the DeltaV controller.
Key Selling Points & Differentiators
- Exact Series 2 Plus Match: Guaranteed compatibility with DeltaV Series 2 Plus carriers; not recommended for Series 1 or non-Plus Series 2 racks.
- High-Density Relay Output: Consolidates 32 discrete relay outputs into a single module footprint, minimizing cabinet space and wiring complexity.
- Isolated Relay Switching: Each channel provides isolated relay contacts rated for 24V DC, protecting the backplane from field-side voltage spikes.
- Rigorous Live Bench Testing: Every unit undergoes a 24-hour continuous load test and full-scale I/O simulation before shipping.
- New Surplus Availability: Factory-sealed condition with verified source traceability, bypassing typical OEM lead times.
- Anti-Counterfeit Verification: Serial numbers are checked against manufacturer databases during incoming inspection to guarantee authenticity.

FAQ
No. The “S1” designation confirms this is Series 2 Plus hardware. Series 1 carriers have different backplane pinouts and mechanical keying. Forcing this module into a Series 1 rack will damage the backplane connectors and void any warranty.
I have a VE4002S1T2B4 on hand. Can I use it as a direct replacement?
The B4 and B5 variants typically denote terminal block revisions or minor firmware updates. While they are often mechanically compatible, you must verify the terminal pitch and pinout against your existing field wiring. Always check the DeltaV hardware manual for backward compatibility notes before swapping suffixes.
Do I need to configure anything in DeltaV Explorer before installing?
Yes. The controller must be configured to recognize the module type and map the 32 output channels correctly in the control strategy. I always recommend backing up your database and running a hardware scan after insertion to ensure the controller reads the module ID properly.
What happens if I wire an active 24V source instead of a dry contact?
This module is strictly rated for relay output switching. Applying an active voltage source directly to the output terminals can blow the internal channel fuses or damage the backplane isolation. If your field device requires an active 24V signal, verify that the relay contacts are properly wired to pass the voltage through.
Is there a warranty on this new surplus unit?
Yes. All new surplus modules come with a standard 12-month functional warranty. If the unit fails during normal operation within that period, we provide a direct replacement. We also include our internal test report with every shipment so you can verify the 24-hour load test results before installation.
