SE4303T02 Emerson DeltaV Thermocouple/mV Input CHARM

Product Description

The Emerson SE4303T02 is a Thermocouple/mV Input CHARM for the DeltaV Electronic Marshalling system. It acquires temperature signals from thermocouples and low-level millivolt signals from compatible field instruments, then converts them into measurement data for DeltaV control processing. Furthermore, it features integrated cold junction compensation (CJC) and a 24-bit A/D converter for thermocouple and millivolt signal measurement.

Technical Specifications

Input Signal and Measurement

The SE4303T02 accepts signals from eight thermocouple types: B, E, J, K, N, R, S and T. In addition, it supports low-level millivolt inputs across three selectable measurement ranges: +/-20 mV, +/-50 mV and +/-100 mV.

The integrated cold junction compensation accounts for the reference junction temperature when measuring thermocouple signals. Meanwhile, its 24-bit A/D converter digitizes the analog input signals for processing by the DeltaV control system.

Configuration and Terminal Block

The SE4303T02 uses the CHARM architecture within Emerson DeltaV Electronic Marshalling. Its modular design supports individual field signal conditioning and I/O configuration.

The associated SE4504 Thermocouple/mV Terminal Block provides the terminal connection for the thermocouple/mV input configuration. Furthermore, SE4303T52 identifies the combined CHARM and terminal block assembly, which is useful when checking the required hardware configuration.
