Description
Daejoo High-Precision Current Transducer
Model: DT-1A-A1AA (DT1AA1AA) | Industrial Signal Transmitter
Used Condition
— Genuine industrial automation take-out. The internal isolation circuitry, primary bus/cable pass-through, rear terminal connector pins, and housing snaps have been fully cleaned, inspected, and verified for safe field redeployment.
Product Overview
The genuine Daejoo DT-1A-A1AA (also referenced as DT1AA1AA) Current Transducer is a highly accurate and reliable process instrument designed for precise current monitoring, isolation, and control loops within heavy industrial setups. This precision module monitors alternating or direct electrical currents passing through the sensing window and scales them down into a highly stable, proportional analog output signal. Engineered to interface seamlessly with remote PLCs, SCADA frameworks, and digital telemetry meters, it acts as a critical line of defense for overload diagnostics, phase balance monitoring, and automated system safety profiling.

Key Features & Operational Benefits
- High Galvantic Electrical Isolation: Completely isolates high-power primary lines from sensitive control boards, shielding data processing units from spike anomalies.
- Linear Signal Linearization: Provides highly uniform calibration tracking, ensuring the conversion remains accurate even during fluctuating line frequencies.
- Excellent Long-Term Stability: Manufactured using industrial-grade internal compensation circuits that prevent thermal drift under steady power cycles.
- Robust Housing Assembly: Features a flame-retardant composite casing with deep-set channel terminal blocks to prevent debris contact or accidental short-circuits.
Logistics & Commercial Handling
Secure Bubble Transit Packaging: To fully isolate the precise magnetic core tracking windows, inner conditioning boards, and terminal pins from physical transit friction, this transmitter is enveloped in an anti-static shield layer and packaged into a thick, impact-absorbing outer shipping box. Standardized online freight tracking is assigned immediately upon checkout.
