The RTD Converter is a versatile 1-channel isolated barrier designed for use in demanding industrial environments. It supports 24 V DC supply and is compatible with 2- or 3-wire Pt100 RTD inputs, providing a reliable output of 4 mA to 20 mA with selectable temperature linearization.
The RTD Converter is part of a specialized family of intrinsic safety barriers that enable safe temperature measurement in hazardous areas. These devices are crucial for applications where temperature control and monitoring are essential, such as in chemical processing, oil and gas, and other industrial sectors that require stringent safety measures. The isolated barrier design ensures that any potential faults in the measurement circuit do not affect the overall safety of the system.
This converter is particularly beneficial in scenarios that demand high accuracy and reliability. By integrating features like DIP switch selectable ranges and sensor breakage detection, it enhances operational efficiency and reduces the risk of failure in temperature measurements. The ability to utilize both 2- and 3-wire Pt100 RTD inputs allows for flexibility in sensor configuration, making the RTD Converter a suitable choice for various applications across different industries.
