Product Introduction
Integrating legacy field wiring into modern control architectures often requires exact hardware matching. The Emerson is a 32-channel discrete input card designed specifically for the DeltaV Series 2 Plus platform. It provides a direct, drop-in interface for acquiring 24V DC dry contact signals from field sensors, limit switches, and relay outputs.
This unit is engineered to deliver reliable digital state detection across all 32 channels simultaneously. Field deployments confirm that maintaining the exact Series 2 Plus terminal block specification prevents backplane communication faults and ensures accurate diagnostic reporting to the host 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 Acquisition: Consolidates 32 discrete inputs into a single module footprint, reducing cabinet space and backplane wiring complexity.
- Verified Dry Contact Input: Configured specifically for 24V DC dry contact logic, eliminating the need for external signal conditioning relays.
- 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 “S2” in the part number designates Series 2 Plus hardware. Series 1 carriers have different backplane pinouts and mechanical keying. Attempting to force this module into a Series 1 rack will damage the backplane connectors.
I have a VE4001S2T2B5 on hand. Can I use it as a direct replacement?
The B5 and B6 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. Even though this is a discrete input card, the controller must be configured to recognize the module type and map the 32 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 dry contact inputs. Applying an active voltage source directly to the terminals can blow the internal channel fuses or damage the backplane isolation. If your field device outputs an active 24V signal, you need an intermediary relay or a different I/O card rated for active inputs.
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.
