The Resistance Repeater is a sophisticated 1-channel isolated barrier designed for use in intrinsic safety applications. With a 24 V DC supply and compatibility with various resistance and RTD inputs, it ensures high accuracy and reliability in measurement tasks.
The Resistance Repeater is a critical component in the Pepperl+Fuchs family of intrinsic safety barriers, designed to enhance the safety and reliability of measurement systems in hazardous environments. This device is particularly useful for applications involving resistance and RTD sensors, such as Pt100, Pt500, and Pt1000, making it ideal for temperature measurement and process control in various industrial settings.
With an accuracy of 0.1%, the Resistance Repeater ensures precise data transmission, which is crucial for maintaining operational integrity and safety. The inclusion of line fault detection (LFD) for Pt100 sensors further enhances its reliability, providing operators with real-time monitoring capabilities. The compact housing, with a width of only 12.5 mm, allows for efficient use of panel space without compromising on performance, making it a valuable addition to systems that adhere to safety integrity levels (SIL 2) according to IEC 61508 standards.
