Product Description

The MCR-VDC-UI-B-DC is a signal conditioning module from Phoenix Contact, part of their MCR (Modular Concept for Rail-mounted Signal Conditioning) series. It is used for signal conversion and isolation of DC voltage signals in industrial applications, ensuring safe and reliable transmission of electrical signals between different parts of a system. The module provides galvanic isolation between input and output signals, which is critical for protecting sensitive equipment from electrical noise, transients, and ground loops.

This module is typically used for applications requiring the safe conditioning and transmission of voltage signals, often in control panels, automation systems, and measurement equipment.
