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

The Yokogawa 246954-540-AFA-0-0 JDF Transducer is a power transducer in the Yokogawa JUXTA 2469 series that converts AC electrical parameters into a proportional DC signal for control and instrumentation, designed for reliable signal conversion in utility and industrial environments with high immunity to electrical disturbances. It accepts 120 VAC input (code 540) and 5 A AC from current transformers, operates at 50/60 Hz, and provides a 0–1 mA DC output (AFA code) with industrial-grade accuracy near ±0.5% typical, housed in a rugged metal case for panel or DIN rail mounting. In real-world systems, it is used in switchboards, substations, and automation panels to measure power parameters via CTs and PTs and transmit the results to PLC, DCS, or SCADA systems for real-time monitoring, control, and energy management.
