The Temperature Repeater is a 1-channel isolated barrier designed for precise temperature measurement and control in hazardous environments. It supports a 24 V DC supply and is compatible with various resistance and RTD inputs, ensuring accurate readings and reliable performance.
The Temperature Repeater belongs to the Pepperl+Fuchs family of intrinsic safety barriers, which are essential in applications where safety and reliability are paramount, particularly in explosive atmospheres. This device is engineered to convert temperature signals from resistance temperature detectors (RTDs) and resistance inputs into isolated, standardized outputs. Its compact housing design facilitates integration within various industrial setups while adhering to stringent space requirements.
Common applications for the Temperature Repeater include monitoring and controlling temperature in process industries, chemical plants, and other environments where hazardous materials may be present. With an accuracy of 0.1%, it ensures precise measurements, while features such as line fault detection for Pt100 inputs enhance system safety. Additionally, the device meets up to SIL 2 standards according to IEC 61508, making it suitable for use in safety-critical applications.
