Emerson KL4501X1-BB1 Address Plug

Product Overview

The Emerson KL4501X1‑BB1 is an Address Plug (Plug #2, code 1C) used in the DeltaV™ Electronic Marshalling CHARM I/O subsystem. It assigns a unique address to each CHARM module within an I/O baseplate, enabling the DeltaV control system to automatically identify and configure CHARM channels. Specifically designed for hazardous‑area environments (Zone 2/Div 2), it integrates keying to prevent mis‑insertion and ensure safe, reliable signal assignment.

Key Features

• Unique address designation for CHARM terminal blocks (Plug #2 = address 2)

• Rotary‑keyed insertion ensures correct pairing with terminal blocks

• Hazardous area rated (Zone 2 / Class I Div 2)

• Non‑sparking; field power must be de‑energized before insertion or removal

• No calibration or user serviceable parts required

• Compatible with DeltaV CM S/MS and Electronic Marshalling hardware

Technical Specifications

Industry Applications

• DeltaV™ Electronic Marshalling installations using CHARMs and terminal blocks

• Industrial automation in oil & gas, chemical, and power generation facilities

• Hazardous location applications where proper address assignment is critical

• CHARM I/O configuration for field-mounted or cabinet-installed systems

Product Advantages

• Ensures correct channel addressing and auto‑configuration with DeltaV software

• Rotary keying prevents mismatched or reversed plug‑block pairing

• Certified for safe use in Zone 2 / Class I Div 2 hazardous areas

• Simple plug-in design; service-free and calibration-free

• Enables flexible CHARM readdressing without rewiring
