The Autonics developed the MT4W-AV-48 as a high-performance Digital Panel Meters with Diverse I/O solution to ensure precise and dependable voltage and frequency readings in factory conditions. Its 4-digit 7-segment LED display with 14.2mm character height enables excellent readability across a full display range of -1999 to 9999. The device supports wide input variations, including 0–500V, 0–250V, 0–110V down to 0–1V, making it ideal for monitoring both high and low-voltage signals across dynamic loads.
This model utilizes a fast and stable ΣΔ (Sigma-Delta) ADC and a 16.6ms sampling cycle to deliver accurate RMS and AVG value readings. It operates reliably with a 100–240VAC 50/60Hz power supply and achieves ±0.3% F.S. ±3 digits accuracy at 23°C for voltage, and ±0.1% F.S. ±2 digits for frequency. The MT4W-AV-48 includes an NPN open collector output (HI, GO, LO) and an RS485 communication interface, offering seamless integration with SCADA, PLCs, and remote control systems.
With IP56-rated front protection, reinforced insulation (1kV dielectric strength), and an external hold function, the unit is tailored for both safe operation and maintenance efficiency. It remains stable across industrial ambient conditions ranging from -10°C to 50°C and 35% to 85% relative humidity. Compact and lightweight at just ≈211g, the MT4W-AV-48 embodies both robustness and convenience.
