Emerson SE4303T01 AI 4-20 mA HART CHARM

Overview

The Emerson SE4303T01 is a DeltaV™ CHARM (Characterization Module) designed for analog input signals. It supports 4–20 mA with or without HART communication. This module simplifies field wiring by eliminating traditional marshalling cabinets. It integrates directly with 2-wire, 3-wire, and 4-wire devices, enabling scalable and flexible I/O in Emerson’s Electronic Marshalling system.
