Yokogawa Electric Corporation 246954-540-AHD-0-0 Transducer

The Yokogawa 246954-540-AHD-0-0 Transducer is a power transducer designed to convert AC electrical measurements into a 4–20 mA analog signal for monitoring and control in industrial power systems. The unit accepts 120 VAC input with a typical 5 A AC CT input and operates at 50/60 Hz, delivering a 4–20 mA DC output (AHD code) that represents the measured parameter. With an accuracy of approximately ±0.5% of span, it supports panel or DIN rail mounting in a metal and plastic housing, though the unit shown has cosmetic damage and missing screws. It is commonly used in switchboards, substations, and electrical distribution panels to interface CTs and PTs with PLC, DCS, or SCADA systems for real-time power monitoring and energy management in industrial and utility environments. The Yokogawa JUXTA Series part is closely related to replacements such as Yokogawa 248954-540-AHD-0-0 and 246953-540-AHD-0-0 Transducers, as well as Siemens 7NG Series equivalents.
