7NG0410-1BB00-0AA0-ZC20 SIEMENS Exclusive SITRANS TH420 Temperature Transmitter Original Brand New

The SIEMENS 7NG0410-1BB00-0AA0-ZC20 SITRANS TH420 is a highly reliable temperature transmitter engineered for precise temperature measurement in industrial applications. Designed for installation in connection heads type B (DIN 43729), this transmitter features two independent configurable inputs and a galvanically isolated 2-wire output with HART communication protocol (4 to 20 mA). Its dual input mode provides redundancy and drift detection, ensuring higher process availability and reliable performance in demanding environments. Compact, versatile, and efficient, the SITRANS TH420 is a proven solution for both general-purpose use and safety-critical applications in accordance with IEC 61508.

With universal compatibility, the transmitter supports a wide range of temperature sensors and signal sources, making it a flexible choice across industries. Its intelligent diagnostics, redundant input capability, and compact design contribute to reduced downtime, easier maintenance, and optimized process reliability. Whether deployed in process automation, energy, or manufacturing sectors, this transmitter is tailored for modern industrial requirements.

Overview

The SITRANS TH420 is a 2-wire head-mounted transmitter equipped with a HART/PA communication interface. It is specifically designed for mounting in the connection head of the temperature sensor. With its universal input configuration, the device supports almost any type of temperature sensor, while dual input circuits enable redundant operation and drift detection. Configuration is made simple through HART 7 or Profibus PA, allowing for streamlined commissioning and monitoring.

Application

The SITRANS TH420 transmitter is suitable for use across all industrial sectors due to its compact design and universal input module. It can be installed in type B or larger connection heads and is compatible with multiple sensor types, including resistance thermometers (2-wire, 3-wire, and 4-wire), thermocouples, linear resistors, potentiometers, and DC voltage sources. The output delivers a standard 4 to 20 mA signal, load-independent, with HART digital communication or Profibus PA.

Its redundant input design enhances system availability and provides drift detection, allowing maintenance to be planned proactively. Furthermore, transmitters designed for hazardous environments can be deployed in areas requiring ATEX, FM, CSA, and other global certifications. The SITRANS TH420 ensures dependable operation, safety compliance, and flexibility in a wide range of industrial applications.
