SYSTEM RELATIONSHIP

One Analog Path, Two Data Layers

◉

Field transmitter

Produces the process current and superimposed HART communication.

▣

VE4003S2B2 + card

Fuses the field path, converts current and passes HART traffic.

⌘

DeltaV and AMS

Uses process values in control while exposing device variables and status.

Installation sequence

01 Match card, keying and assigned carrier slot.	02 Seat VE4003S2B2 and use the specified fuse arrangement.
03 Land each loop with correct polarity and loop supply.	04 Enable only required HART channels and bind control tags.

FAMILY COMPARISON

Choose the Termination Style by Wiring Method

Model	Termination	Practical advantage
VE4003S2B1	Standard	Direct conventional field landing
VE4003S2B2	Fused	Field-path fuse at the termination point
VE4003S2B3	4-wire	Supports separately powered transmitters
VE4003S2B4 / B5	16-pin / 24-pin mass	Prewired cabinet and marshaling schemes

BUYER FAQ

Questions That Affect the Architecture

❖ Q Can KJ3221X1-BA1 12P2531X122 VE4003S2B2 communicate with HART devices from different vendors?	◉ A Yes, when the field device follows compatible HART signaling and the loop impedance, power budget and DeltaV device integration are suitable.
◆ Q What is gained by choosing VE4003S2B2 for KJ3221X1-BA1 12P2531X122?	◉ A The B2 variant places a fuse option at the termination block. It is useful when the cabinet design requires localized field-circuit protection.
◇ Q Does KJ3221X1-BA1 12P2531X122 VE4003S2B2 scan every HART channel continuously?	◉ A Only enabled HART channels participate. Typical scan time is 600–800 ms for each enabled channel, so the enabled count affects the update cycle.
✦ Q Can KJ3221X1-BA1 12P2531X122 VE4003S2B2 be used redundantly?	◉ A Redundant operation depends on the supported card and carrier arrangement. Budget LocalBus current at up to 250 mA per card for the redundant condition.
❖ Q When is VE4003S2B3 preferable to VE4003S2B2 on KJ3221X1-BA1 12P2531X122?	◉ A Choose the B3 termination when the project uses separately powered 4-wire transmitters. Choose B2 when fused conventional 4–20 mA loop termination is the priority.
