Features:

  • 4–20 mA analog-input measurement with HART communication
  • Individual CHARM channel characterization for flexible Electronic Marshalling
  • 1A terminal keying with no calibration requirement
SE4303T01 KL3021X1-BA1 provides one DeltaV Electronic Marshalling input channel for a compatible two-wire or externally powered 4–20 mA field signal.

HART communication keeps supported device variables and diagnostics available alongside the process current, improving commissioning and maintenance visibility.

The keyed CHARM format supports controlled channel replacement while the specified power, enclosure and hazardous-area requirements preserve the intended installation boundary.

For SE4303T01 KL3021X1-BA1 AI 4–20 mA HART CHARM sourcing, Apter Power can help confirm the Emerson model, terminal key and installed DeltaV architecture.

Description
SE4303T01 KL3021X1-BA1 accepts a 4–20 mA analog input while retaining HART communication for supported field instruments. The CHARM architecture moves channel characterization to the individual I/O point, helping project teams standardize cabinets and assign signals without conventional card-level grouping.

SE4303T01 KL3021X1-BA1 uses terminal key 1A and operates across the specified DeltaV CHARM environmental range. The module requires no calibration and contains no user-serviceable parts, so replacement work should focus on exact identity, keyed terminal fit, loop power and approved hazardous-area procedures.

Technical notes
Before installing SE4303T01 KL3021X1-BA1, verify 1A terminal keying, CHARM bus power and the 24 VDC field circuit. The module requires no calibration and has no user-serviceable parts. Confirm loop polarity and enclosure protection. In hazardous locations, de-energize or confirm a nonhazardous atmosphere before insertion, removal or field-wiring changes.
