Emerson KL4502X1-MA1 Relay Output Terminal CHARM

Product Description

The Emerson KL4502X1-MA1 is a CHARM relay output terminal carrier for DeltaV distributed control systems (DCS). It provides a secure mechanical and electrical foundation for CHARM I/O modules, allowing reliable communication between the DeltaV controller and field devices. Moreover, it integrates with Emerson’s Electronic Marshalling technology, which eliminates traditional marshalling panels, simplifying field wiring and installation. Therefore, system expansion is flexible, grounding is properly maintained, and modules can operate safely in hazardous areas. Its compact design supports efficient rack or backplane installation, ensuring continuous 24/7 operation in industrial automation environments.
