Overview Manuals Circuit & Enclosure Automatic Keying Service Boundaries Product Applications

Features:

  • Injected-power terminal: Rated at 250 VAC and 1 A for the terminal-power path.
  • Automatic keying: The key position is set during initial CHARM installation.
  • Conditional powered handling: Removal under system power requires two explicit no-energy conditions.
KL4502X1-LA1 identifies the fused injected-power terminal-block hardware used at a DeltaV CHARM position.

Automatic keying records the first installed CHARM type and makes a later type change dependent on releasing the locked keys.

Environmental and maintenance limits define the enclosure and service conditions without implying universal CHARM compatibility.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Circuit ceiling: Select KL4502X1-LA1 only when the injected-power path remains within the documented 250 VAC, 1 A terminal rating.
  • Ambient decision: The enclosure must keep the terminal block inside its -40°C to +70°C operating range.
  • Moisture and contaminants: Non-condensing humidity and ISA G3 define the documented cabinet environment, not approval for harsher exposure.
  • Mechanical qualification: Compare the installed CHARM position with the published shock and 2–150 Hz vibration profile before release.
  • First installation: The terminal-block keys are set automatically when a CHARM is first installed.
  • Locked position: The key setting is retained for the installed terminal position.
  • Different CHARM type: Remove the terminal block before resetting the keys.
  • Reset action: Release the keys from their locked position before installing the different type.
  • Powered removal condition: No CHARM may be installed.
  • Field-wiring condition: No energized field wiring may be connected to the terminal.
  • Internal repair: The unit contains no user-serviceable parts and must not be disassembled.
  • Calibration: Periodic calibration is not required.
  • Injected-power CHARM positions: Provides the fused terminal-power interface for the specified DeltaV channel hardware.
  • Keyed terminal installations: Records the first installed CHARM type through automatic key setting.
  • Industrial enclosures: Serves panels maintained within the published environment and terminal rating.
  • Hazardous-location projects: Applies only with the separate Zone 2 installation instructions and exact product markings referenced by Emerson.
Description
KL4502X1-LA1 provides a fused injected-power terminal-block position for a DeltaV CHARM channel. Its 250 VAC at 1 A terminal-power rating gives panel designers a precise electrical boundary for selecting the field circuit and documenting the installed terminal type.

KL4502X1-LA1 automatically sets its key position when a CHARM is first installed. That physical configuration helps preserve the intended terminal-to-CHARM arrangement, while Emerson’s reset procedure defines the additional work required before a different CHARM type is fitted.

Technical notes
KL4502X1-LA1 may be added or removed with system power applied only when no CHARM is installed and no energized field wiring is connected to the terminal. If either condition is not met, stop the work and isolate the relevant circuit before handling the terminal block. This is not unrestricted hot-swap.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When is KL4502X1-LA1 the correct terminal-block selection for a CHARM position?
Select KL4502X1-LA1 when the installed design calls for the fused injected-power terminal block and the terminal-power circuit remains within 250 VAC at 1 A. Match the complete model before ordering.
What happens to the key position when KL4502X1-LA1 receives its first CHARM?
The terminal-block keys are set automatically during the first CHARM installation. That locked setting becomes part of the physical configuration for the terminal position.
How is KL4502X1-LA1 prepared for a different CHARM type?
Remove the terminal block and release the keys from the locked position before installing the different CHARM type. Do not force a new module into the existing key arrangement.
Does KL4502X1-LA1 require calibration or component-level repair?
No calibration is required, and the terminal block has no user-serviceable parts. Replace the complete terminal block rather than disassembling it when an internal defect is confirmed.
Which cabinet environment applies to KL4502X1-LA1?
Keep the terminal block within -40°C to +70°C and 5% to 95% non-condensing humidity. Include the specified shock, vibration and ISA G3 contaminant limits in the enclosure review.
How should the hazardous-area markings for KL4502X1-LA1 be interpreted?
They are the markings and certificate identifiers shown on Emerson ATEX125 for this terminal block. The complete installation still has to follow the referenced CHARM I/O Zone 2 instructions; the sheet does not certify the whole cabinet.
