The Temperature Converter is a versatile 2-channel isolated barrier designed for use in hazardous environments. It supports thermocouple, RTD, and potentiometer inputs, making it suitable for a variety of temperature measurement applications.
The Temperature Converter is engineered to provide reliable and safe temperature measurements in industrial settings where intrinsic safety is paramount. This device allows for the integration of multiple input types, including thermocouples, RTDs, and potentiometers, ensuring compatibility with a wide range of sensors used in process automation.
As a 2-channel isolated barrier, it can function as a signal splitter, offering one input with two outputs, which facilitates the distribution of temperature signals to multiple systems or devices. The linearized output options of 4 mA to 20 mA or 1 V to 5 V ensure that the temperature readings are easily interpretable by various control systems. Additionally, built-in features such as sensor breakage detection and line fault detection (LFD) enhance operational reliability, making it a valuable component in critical applications.
This device is configurable via PACTware, allowing users to tailor its settings to meet specific operational requirements. With its compliance to SIL 2 standards as per IEC 61508/IEC 61511, the Temperature Converter is suitable for use in safety-critical applications, ensuring that temperature monitoring adheres to the highest safety standards.
