Product Description: Emerson KL4502X1-DA1 CHARM Address Terminal Block

The Emerson KL4502X1-DA1 is a compact CHARM address terminal block engineered for DeltaV Electronic Marshalling systems. It helps technicians connect field devices without using traditional marshalling racks, enabling cleaner panel layouts and faster project execution. Moreover, its integrated address plug ensures correct module recognition, which simplifies commissioning activities across mixed-signal environments.

This terminal block suits teams who manage large I/O expansions, because it maintains secure terminations while supporting automatic addressing inside DeltaV CHARM architectures. In addition, the device meets global hazardous-area standards, giving engineers dependable performance in oil, gas, chemical, or energy operations. The lightweight assembly installs quickly, and the rigid enclosure design supports reliable operation in demanding climates from –40°C to +70°C.
