More Information

Overview Manuals Protection Role Fit and Keying Receiving Match Product Applications

Features:

  • Unused-position protection: Shields an unpopulated CHARM Terminal Block from damage.
  • All-terminal-block fit: Emerson states that the cover fits every CHARM Terminal Block type.
  • Key setting preserved: The installed terminal-block key remains unchanged.
KL4502X1-QA1 is the protective accessory identified for terminal-block positions that do not currently hold a CHARM.

Its universal terminal-block fit avoids selecting a different cover for each CHARM Terminal Block type.

The unchanged key setting keeps the protected position mechanically identified for later work.

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.
  • Protected object: The cover installs on an unused CHARM Terminal Block.
  • Purpose: It protects the unpopulated terminal block from damage.
  • Accessory boundary: The cover is not a signal-conditioning CHARM.
  • Installed state: Use it where the terminal block remains present but no CHARM is installed.
  • Terminal-block coverage: KL4502X1-QA1 fits all CHARM Terminal Blocks.
  • Key position: Installing the cover does not affect the existing key setting.
  • Future channel work: The protected terminal block retains its mechanical key identity.
  • Selection limit: The universal fit applies to CHARM Terminal Blocks, not unrelated terminal hardware.
  • Identity pair: Require KL4502X1-QA1 together with 12P7250X012 so the received accessory is tied to the documented protection-cover item.
  • Product wording: CHARM PROTECTION COVER distinguishes this passive cover from an active CHARM or I/O module at receiving.
  • Revision record: Keep REV B as an item-level receiving detail without adding it to the complete product model.
  • Mismatch action: Hold the item for review when the model, manufacturer number or product wording does not agree with the request.
  • Unused CHARM positions: Protect terminal blocks that are installed without a CHARM.
  • Deferred channel population: Cover a terminal-block position until its CHARM is installed.
  • Maintenance staging: Protect a terminal block that remains temporarily unpopulated during planned work.
  • Mixed terminal-block layouts: Use one cover type across the CHARM Terminal Block variants named by Emerson.
Description
KL4502X1-QA1 covers an unused CHARM Terminal Block to protect it from damage while the terminal position is not populated. Keeping the terminal block protected preserves the installed hardware for a later channel assignment without treating the cover as an I/O device.

Because KL4502X1-QA1 fits all CHARM Terminal Blocks and leaves the existing key setting unchanged, maintenance teams can protect an open position without altering its configured mechanical identity. The complete model and 12P7250X012 order marking should remain together through quotation and receiving.

Technical notes
KL4502X1-QA1 is intended for an unused CHARM Terminal Block and does not change that block’s key setting. It is a protective accessory, not a CHARM or a keying device; install it only on an unpopulated terminal block and use the instructions supplied with the cover for the installation method.

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.
Can KL4502X1-QA1 be installed when a CHARM Terminal Block has no CHARM fitted?
Yes. That is its stated role: the cover protects an unused CHARM Terminal Block from damage while the terminal block remains installed.
Does KL4502X1-QA1 require a different version for each CHARM Terminal Block type?
No. Emerson states that the protection cover fits all CHARM Terminal Blocks, so cover selection is not divided by terminal-block type.
Will KL4502X1-QA1 change the mechanical key setting of the protected terminal block?
No. The cover does not affect the terminal-block key setting, allowing the position to retain its existing mechanical identity.
Which manufacturer number should purchasing use with KL4502X1-QA1?
Use 12P7250X012 together with the complete model. The photographed item also carries the product wording CHARM PROTECTION COVER and REV B.
Should receiving accept KL4502X1-QA1 as an I/O module or CHARM?
No. Receive it as a protection cover for an unused CHARM Terminal Block, not as a signal-conditioning CHARM or an active I/O device.
What installation reference should maintenance use for KL4502X1-QA1?
Use the instructions provided with the protection cover. The AMS Asset Monitor guide establishes its purpose, fit and key-setting behavior but directs installation details to the cover documentation.
