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

• DeltaV™ Electronic Marshalling configurations requiring precise channel addressing

• Hazardous-location installations in oil & gas, chemical, power generation, and refining

• Remote/field-mounted CHARM I/O applications

• Systems requiring error-resistant plug-block mapping

• DeltaV instrumentation setups where auto-configuration is needed

Product Advantages

• Ensures proper channel-to-plug mapping for CHARM baseplates

• Prevents mis-wiring via keyed connector design

• Suitable for hazardous environments without additional enclosures

• Easy, maintenance-free solution for addressing CHARM modules

• Simplifies configuration by eliminating manual channel numbering

• Compatible with all DeltaV™ CHARM-based systems

Frequently Asked Questions (FAQ)

1. What address does this plug assign?

   Address #3 (terminal key position 1E).

2. What power does it draw from the CHARM bus?

   Approximately +6.3 VDC at 2 mA.

3. Can I insert or remove it under full system power?

   No—field power must be removed unless the area is non-hazardous.

4. Is this plug keyed to prevent mis-installation?

   Yes—keying ensures correct plug-to-slot alignment.

5. Is calibration required for this device?

   No—there are no user-adjustable or serviceable components.

6. What environmental conditions can it withstand?

   It is rated for –40 °C to +70 °C, high humidity, vibration, and shock.

7. Is it certified for hazardous locations?

   Yes—it meets ATEX Zone 2 and FM Class I Div 2 standards.

8. What happens if the wrong plug number is used?

   Channels may be misaddressed, requiring manual reset or fixture reprogramming.

9. What is its weight?

   Approximately 0.05 kg.

10. How does it integrate into the DeltaV system?

    It plugs into the numbered address position on the CHARM terminal block in the CHARM baseplate.
