The KL4501X1-BB1 address plug assigns a unique identity to each CHARM in a DeltaV electronic marshalling cabinet. Emerson engineers this small component to simplify channel configuration during commissioning. It sets the hardware address without software tools or manual jumper changes.
Address Encoding and Interface Details
The plug carries a factory-set address code that the CHARM base reads on insertion. Eight contact pins mate with the base connector and transmit the identity value. Each plug serves one CHARM slot, which keeps addressing unambiguous across a cabinet. Moreover, the molded keying prevents incorrect orientation during installation.
Physical Dimensions and Materials
The component measures 22 mm in length, 16 mm in width, and 12 mm in depth. It weighs approximately 15 g, so it adds negligible load to the carrier. The polycarbonate body resists impact and flame, and it tolerates temperatures up to 120 °C. A colored cap identifies the plug type at a glance.

Installation and Commissioning Notes
Technicians press the KL4501X1-BB1 into the CHARM base until the latch clicks. The base then reports the address to the controller during network discovery. Colored caps let crews match plugs to channel types quickly. Therefore, marshalling cabinet checkout moves faster and errors drop.
Why This Plug Simplifies CHARM Cabinets
Engineers specify the KL4501X1-BB1 for its tool-free installation and rugged polycarbonate body. Hardware addressing removes the need for software setup at each slot. The compact size keeps cabinet depth requirements low. This plug suits electronic marshalling builds in refineries, chemical plants, and power stations.
