A82-20500 is a true RMS AC current metering transformer designed to convert AC current measurements into a standardized 4–20 mADC sink output signal. It features a 500 AAC input current range with output current tolerance of ±2% on full scale at 50 Hz, operating over a frequency range of 40 Hz to 1 kHz. The device provides rated insulation voltage of 1000 VAC rms between input and output, with dielectric strength of 6 kVAC rms and impulse withstand voltage of 12 kV (1.2/50 µs), ensuring robust isolation and safety. The transformer requires a loop voltage supply of 10–40 VDC and delivers a maximum output current of 30 mADC, making it ideal for direct connection to PLCs, monitoring relays, and setpoint control systems. Its compact housing (95 × 67.5 × 20 mm) with IP 40 protection and integrated green LED power indication simplifies installation and diagnostics in industrial monitoring applications.
