Yokogawa DU300-11 DC Current Input Module, 10-Channel, ±20mA, 0.5s Interval

Description:

The Yokogawa DU300-11 DC Current Input Module is a 10-channel analog input module used in Yokogawa DA100 and DARWIN data acquisition systems for measuring and monitoring ±20 mA process signals. Commonly installed in industrial control panels, power plants, chemical processing facilities, and water treatment systems for collecting transmitter signals such as flow, pressure, and level. Maintenance teams and system integrators use this part for system expansion, replacement of faulty modules, and ensuring accurate multi-channel current signal acquisition in process monitoring applications.

Applications:

The Yokogawa DU300-11 is used in industrial data acquisition and process monitoring systems to capture 4–20 mA signals from field instruments. It is widely applied in oil and gas facilities, power generation plants, wastewater treatment systems, and manufacturing environments where continuous monitoring of process variables is required. The module integrates into Yokogawa DA100 and DARWIN platforms, enabling scalable, high-density signal acquisition with consistent and reliable performance across multiple channels.
