Autonics MT4Y-DA-44 Digital Panel Meter

The Autonics MT4Y-DA-44 delivers precision DC current measurements with a bright 4-digit 7-segment LED display and a large 14.2mm character height. Its measurement range spans from -1999 to 9999, compatible with multiple input types including 0–5A, 4–20mA, and 0–500mA, making it versatile for industrial load and sensor monitoring. This model operates efficiently on 100–240VAC at 50/60Hz and provides high accuracy up to ±0.1% F.S. ±2 digits at standard ambient conditions (23°C), ensuring reliable performance even under fluctuating loads.

Equipped with both a Relay (LO) output for comparative alerts and an RS485 serial communication interface, the MT4Y-DA-44 seamlessly integrates with PLCs, SCADA systems, and networked data loggers. Its Sigma Delta (ΣΔ) A/D converter enables a rapid 50ms sampling cycle, minimizing delay in high-speed applications. The meter also includes an external hold function that allows temporary data freezing during equipment testing or calibration. With double insulation and 1kV dielectric strength between measuring and power sections, it is built for safety and stability in high-voltage environments. An IP56-rated front panel further protects against industrial dust and water ingress, making it suitable for panel-mounted use in rugged environments.

Compact at approximately 134g, the Autonics MT4Y-DA-44 fits easily into tight enclosures while delivering the performance and features expected in more advanced systems. Its analog and digital output versatility, coupled with display clarity and strong electrical insulation, make it a reliable choice for engineers seeking both accuracy and integration flexibility.

Maintenance engineers appreciate the visual clarity of the front panel LED, especially when troubleshooting current deviations or fine-tuning analog sensors. The relay output helps trigger alerts when predefined thresholds are crossed, adding a protective layer for connected devices. Thanks to the external hold function, readings can be temporarily frozen during adjustments without data loss, which is particularly helpful during testing or calibration.

For automation students and junior engineers, the MT4Y-DA-44 provides practical experience in analog signal monitoring, RS485 integration, and current loop handling. Whether deployed in testing benches, energy panels, or machine control stations, it delivers consistent performance, robust protection, and valuable real-world insights into current measurement applications.
