EMERSON VE4002S1T2B1 – DeltaV S‑series Temperature Input I/O Module for Reliable RTD/TC Measurements

The EMERSON VE4002S1T2B1 is an S‑series temperature input module for DeltaV systems, typically used when you need stable, low-noise thermocouple and RTD acquisition on process units and skid packages. From my experience, it’s a straightforward drop‑in on the S‑series carrier, and the T2 terminal style makes field wiring neat when you have mixed sensor types. You might notice that it pairs well with existing DeltaV I/O without extra interface hardware—just wire, configure, and start trending.

Key Features

• Dedicated temperature input module – Designed for RTD and thermocouple signals in DeltaV S‑series racks, minimizing conversion noise and drift.
• Flexible sensor support – Typically supports common TC types (J, K, T, E, N, R, S, B) and RTDs such as Pt100 with 2/3/4‑wire options.
• T2 terminal wiring – The T2 variant helps keep field wiring tidy; in many cases it reduces panel footprint versus ad‑hoc terminal strips.
• Integrated cold‑junction handling – Stable CJ compensation and open‑circuit detection to flag broken probes early.
• Seamless DeltaV engineering – Configured and diagnosed in DeltaV; no third‑party drivers, no extra gateways.
• Backplane powered – Draws power from the S‑series carrier; fewer external power complexities on site.

Related or Supporting Products

• EMERSON VE4002S1T1B1 – Same module function with T1 terminal style; choose based on panel wiring preference.
• EMERSON VE4001S1T2B1 – Analog Input (HART) module; useful when you have 4–20 mA transmitters alongside temperature probes.
• EMERSON VE4005S1B1 – Discrete Input module; good companion for limit switches and status contacts on the same skid.
• S‑series I/O Carriers (4‑/8‑wide) – Required backplane for module power and bus; match carrier width to I/O count.
• S‑series T1/T2 Terminal Blocks – Select T1 or T2 based on wiring scheme, marshalling, and service access.

A maintenance technician on a recent retrofit mentioned the VE4002S1T2B1 “cleaned up our RTD noise without extra isolators,” which seems to be what many plants see when consolidating older temperature cards into S‑series DeltaV.

Installation & Maintenance

• Panel/cabinet – Install on a DeltaV S‑series carrier in a ventilated, grounded enclosure; observe 50 mm top/bottom clearance for airflow.
• Wiring – Use shielded twisted pairs for low‑level TC/RTD runs; ground shields at one end only (cabinet side in most cases).
• Thermocouples – Keep junctions and extension wires of the same type; check cold‑junction placement with T2 terminals.
• RTDs – For long runs, 3‑ or 4‑wire reduces lead resistance error; verify lead compensation settings in DeltaV.
• EMC/safety – Maintain separation from high‑voltage cabling; follow ESD handling when inserting/removing modules.
• Routine upkeep – Periodic terminal re‑torque, channel calibration check against a reference, and DeltaV diagnostics review. Firmware alignment is handled by the DeltaV system where applicable.

Quality & Certifications

• Conforms to industrial standards with CE marking; typically UL/CSA recognized for control equipment.
