YOKOGAWA 246921-380-AHD-1 AC CURRENT TRANSDUCER 246921380AHD1

Description:

The Yokogawa 246921-380-AHD-1 AC Current Transducer is used in industrial electrical systems for converting AC current signals into a proportional DC output signal for monitoring and control. Commonly installed in switchboards, control panels, and power distribution systems requiring accurate current measurement and signal interfacing. Maintenance teams, OEMs, and system integrators use this part for transducer replacement, system upgrades, and integration with PLC, DCS, or SCADA systems.

Applications:

The Yokogawa 246921-380-AHD-1 is used in industrial power monitoring systems where AC current must be converted into a standardized analog signal. It is typically connected to current transformers (CTs) in electrical panels to measure load current and transmit a 4–20 mA signal to monitoring equipment such as meters, recorders, PLCs, or energy management systems. These transducers are widely used in manufacturing plants, utilities, and automation systems for real-time current monitoring and control.
