The ABB Metrawatt GTU0402A27B03C1D06E03 is a precision signal transducer designed for converting and isolating DC current signals within industrial and marine instrumentation systems. This unit accepts a DC 20mA input and provides a scaled DC 20mA output with configurable signal conditioning, powered by an AC auxiliary supply (88–132V). Onboard vessels, transducers of this type are integral to power management systems, engine monitoring panels, alarm and monitoring systems (AMS), and process control instrumentation, ensuring accurate signal transmission between field sensors and control equipment.
Key Features
✓ DC 20mA input and DC 20mA output with signal scaling capability for flexible integration
✓ Wide AC auxiliary supply range (88–132V) suitable for shipboard power networks
✓ Fast response time (TN = 0.3s) for reliable real-time signal processing
✓ Compact DIN-rail or panel-mount design typical of ABB Metrawatt transducer range
✓ Manufactured by ABB Metrawatt GmbH (W. Germany) – proven industrial and marine-grade quality
Marine Applications
Power management and generator monitoring systems requiring isolated signal conversion
Engine room alarm and monitoring systems (AMS) for parameter signal conditioning
Cargo and ballast control panels where accurate current loop signal scaling is essential
Switchboard instrumentation and metering circuits aboard merchant and naval vessels
HVAC, boiler, and auxiliary machinery control systems requiring 4–20mA signal interfacing
Why Marine Engineers Choose
