Yokogawa Electric Corporation DU300-11 DC Current Input Module

The Yokogawa DU300-11 is a 10-channel DC current input module for Yokogawa DA100 and DARWIN data acquisition systems, providing multi-channel ±20 mA signal capture from field transmitters. Each channel uses a floating unbalanced input with inter-channel isolation and is sampled every 0.5 seconds, with a built-in 100 Ω shunt and an A/D resolution of ±20,000 counts. The module supports 4–20 mA process signals (pressure, flow, level transmitters) and mounts in rack/slot installations for industrial panels, power plants, chemical processing facilities, and water treatment systems, integrating with Yokogawa DA100, DARWIN, and DR-series data acquisition systems. It employs low-pass filtering and averaging to improve noise rejection across channels, enabling reliable current signal acquisition for process monitoring and system expansion.
