Autonics MT4W-AA-4N Digital Multi Panel Meter

MT4W-AA-4N is Autonics’ DIN 96 × 48 mm digital multi‑panel meter that displays AC current and frequency on a four‑digit LED readout. The unit uses a 14.2 mm high, 4‑digit 7‑segment display and supports a max indication range of -1999 to 9999. It accepts AC current input in selectable ranges: 0–5 A and the subranges 0–2.5 A, 0–1 A, 0–500 mA, 0–250 mA, 0–100 mA, and 0–50 mA. The device is powered from 100–240 VAC at 50/60 Hz and provides a main output indicator for comparative value. The internal A/D conversion is Sigma‑Delta (ΣΔ) with a sampling cycle of 16.6 ms. Accuracy is specified as ±0.3% F.S. rdg ±3 digits at 23 °C ±5 °C (frequency ±0.1% F.S. rdg ±2 digits) and ±0.5% F.S. rdg ±3 digits from -10 °C to 50 °C. AC measurements report both AVG and RMS values. A hold function is available via external control. The MT4W‑AA‑4N offers IP56 front protection (IEC) and insulation of the measuring input and power parts with dielectric strength of 1 kV, using double or reinforced insulation. Operating ambient temperature is -10 to 50 °C with 35–85% RH (non‑condensing); storage temperature is -20 to 60 °C. Packaged weight is approximately 211 g, with a typical total weight around 326 g. This compact, four‑digit meter is well suited for on‑panel monitoring of AC current and frequency in industrial control panels where a clear, robust, DIN‑panel form factor is required.
