Product Description

The MCR-PT100-U is a signal conditioner from Phoenix Contact designed specifically for use with PT100 temperature sensors. It is part of the MCR (Modular Signal Conditioning and Isolation) family of products, which are used to process signals from field devices (such as sensors) and condition them to be compatible with industrial control systems. The MCR-PT100-U is commonly used in temperature measurement applications where PT100 sensors are employed, ensuring that temperature signals are converted and isolated correctly for control or monitoring purposes.
