The KL4501X1-BC1 address plug gives each CHARM channel a fixed hardware identity in DeltaV marshalling cabinets. Emerson factory-programs this plug with a dedicated address code, which the CHARM base reads at insertion. It removes software addressing steps during cabinet commissioning.
Address Encoding and Contact Interface
The plug stores its address code in hardware, so the value survives power cycles and module swaps. Eight contact pins carry the identity signal to the CHARM base connector. Molded keying blocks reversed insertion and protects both mating parts. Moreover, each plug serves one channel, which keeps addressing unique across the cabinet.
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, and it adds negligible load to the mounting rail. The polycarbonate body resists flame and impact, and it tolerates temperatures up to 120 °C. A colored cap identifies the plug variant during quick visual checks.

Installation and Commissioning Notes
Technicians press the KL4501X1-BC1 into the CHARM base until the latch clicks into place. The base reports the address to the controller during automatic network discovery. Crews check colored caps against channel types before cabinet closeout. Therefore, marshalling checkout moves faster and wiring errors drop.
Why This Plug Fits Electronic Marshalling Projects
Engineers specify the KL4501X1-BC1 for its tool-free fit and rugged polycarbonate body. Hardware addressing eliminates per-slot software setup during commissioning. The compact size keeps cabinet depth requirements low. This plug suits marshalling builds in refineries, chemical plants, and power stations.
