Product Description
Overview
The SE4302T02 from EMERSON DeltaV™ is a digital output (DO) CHARM module engineered for 24 V DC inductive load control. Designed for installation directly in the field, it eliminates the need for traditional marshalling cabinets and complex cross-wiring, reducing installation time, wiring points, and potential failure risks. Its isolated output channels provide reliable performance while protecting downstream circuits.
