Emerson SE4307T01 Analog Input CHARM Module

Overview

The Emerson SE4307T01 is an Intrinsically Safe (IS) Analog Input CHARM designed for the DeltaV™ Electronic Marshalling system. It supports both 4–20 mA and optional 0–20 mA signals. Additionally, it enables HART communication for enhanced device diagnostics. The module works with both 2-wire and 4-wire transmitters. Moreover, it eliminates traditional marshalling cabinets, streamlines wiring, and supports faster commissioning. Its rugged design and certification allow safe use in hazardous areas, including Class I Division 2 and IEC Zone II.
