Yokogawa 246921-380-AHD-1 AC Current Transducer

The Yokogawa 246921-380-AHD-1 AC Current Transducer converts 0–5 A AC current (via CT input) into a proportional 4–20 mA DC signal for monitoring and control in industrial electrical systems. This JUXTA 2469 Series device provides up to 2500 VAC input-to-output isolation, operates at 50–500 Hz, offers approx. ±0.5% accuracy, and runs on 120 V AC auxiliary power (AHD variant) with panel or DIN-rail mounting for installation in switchboards, control panels, or power distribution setups; operating temperature is roughly -20°C to +60°C. Commonly used with CTs to measure load current and transmit to meters, PLCs, DCS, or SCADA systems for real-time monitoring and control. Common replacements include Yokogawa 248921-380-AHD-1 and Yokogawa 246931-380-AHD-1, plus Siemens 7NG3212 as an equivalent signal converter.
