Emerson DeltaV™ CTO CHARM Field housing
Product Description
DeltaV™ customized (CTO) CHARM on-site enclosures offer ready-made solutions to accelerate project implementation and reduce installation costs. The on-site casing has been tested in the factory and can be directly installed on site. Electronic grouping eliminates the traditional I/O design tasks, allowing for on-site wiring and ultimately completing the control strategy.
