Emerson KL4501X1-BC1 Address Plug

Product Overview

The Emerson KL4501X1‑BC1 is an Address Plug (Plug #3, code 1E) used in the DeltaV™ Electronic Marshalling CHARM I/O subsystem. It assigns the unique address “3” to a CHARM terminal block, enabling the DeltaV control system to automatically detect and configure wiring channels. Designed for hazardous-area service (Zone 2/Div 2), it includes keyed insertion functionality to prevent mis-insertion and ensure safe and accurate channel mapping.

Key Features

• Assigns address number 3 within the CHARM terminal-block assembly

• Rotary‑keyed design prevents incorrect installation

• Certified for hazardous environments (Zone 2 / Class I Div 2)

• Safe operation only when field power is removed (non‑sparking device)

• No calibration or adjustment required—plug-and-play

• Integrates with DeltaV™ Electronic Marshalling hardware and CHARM baseplates

Technical Specifications

Industry Applications
