Emerson SE4303T02 DeltaV™ Thermocouple/mV CHARM

Overview

The Emerson SE4303T02 is a Thermocouple/mV CHARM for DeltaV™ Electronic Marshalling systems. It measures temperature and low-level voltage signals with high precision. The module supports thermocouples: J, K, T, E, R, S, B, and N types. It accepts low-level millivolt inputs up to ±100 mV. SE4303T02 ensures signal integrity with galvanic isolation and cold junction compensation. It installs easily into DeltaV™ CHARM I/O cards. Built-in diagnostics detect faults and validate signal quality. Ideal for chemical, power generation, and oil & gas applications.
