Data Concentrator Unit

Description

A Data Concentrator Unit (DCU) is a device or component used in various systems to collect, process, and transmit data from multiple sources. It acts as an intermediary (gateway) between the data sources and the central system, facilitating efficient data management, communication can be wired or wireless.
