Buy Brand New Emerson KL3021X1-LS1 Analog Input CHARM

Product Overview

The Emerson KL3021X1-LS1 is a high-precision Low-Side Analog Input CHARM (Characterization Module) designed for the DeltaV Electronic Marshalling architecture. This module digitizes 4–20 mA analog signals from field transmitters and provides full HART pass-through capability for advanced device diagnostics and asset management. By utilizing a low-side sensing topology, the KL3021X1-LS1 offers a specific wiring alternative for complex grounding requirements in industrial loops. We supply this component as 100% Brand New and Original, ensuring seamless integration into your S-series I/O subsystem.

Technical Specifications

Engineering Advantages

• Eliminates Traditional Marshalling: The CHARM technology allows for "I/O on Demand." You click the KL3021X1-LS1 into any slot on the CHARM I/O Card (CIOC) baseplate, eliminating the need for massive cross-wiring and reducing cabinet space by up to 50%.

• HART Intelligence Integration: This module does more than read a process variable. It enables the DeltaV system to extract device status, calibration data, and secondary variables from smart transmitters, facilitating predictive maintenance strategies.

• Hot-Swappable Maintenance: The module supports full online replacement. You can pull and replace a KL3021X1-LS1 CHARM without disconnecting field wiring or interrupting the power to other modules on the same baseplate, significantly lowering Mean Time To Repair (MTTR).

• Extreme Environment Ruggedization: With a G3 harsh environment rating and an operating range down to -40 C, this module thrives in corrosive atmospheres (such as chemical plants or offshore platforms) where standard electronics often fail due to oxidation or thermal stress.

• Built-in Fault Protection: The KL3021X1-LS1 includes sophisticated internal protection to isolate field-side electrical faults from the CHARM bus, preventing a single instrument failure from cascading into a system-wide shutdown.

FAQs

• What is the difference between a High-Side and a Low-Side AI CHARM like the KL3021X1-LS1?

  The KL3021X1-LS1 (Low-Side) senses the current return path to ground. This is specifically useful in certain legacy wiring schemes or specialized grounding configurations where the high-side of the loop must remain common.

• Does the KL3021X1-LS1 provide power to the field transmitter?

  Yes, the module draws +24 VDC field power from the CHARM baseplane to power 2-wire transmitters, simplified by the integrated 25 mA field circuit power rating.

• How do I ensure the module is installed in the correct terminal block?

  Each CHARM type is mechanically keyed. The KL3021X1-LS1 uses Terminal Block Key Position 1A, which prevents you from accidentally inserting an incorrect CHARM type (like a Discrete Output) into an Analog Input slot.

• Can I use this module in a redundant configuration?

  While CHARMs themselves are single-channel components, you achieve system-level redundancy through the DeltaV CHARM I/O Cards (CIOC) which manage the communication for a bank of up to 96 CHARMs.
