The Autonics MT4Y-AA-43 is a high-precision digital panel meter designed to display AC current and frequency with clarity and accuracy. It features a 4-digit 7-segment LED display with a 14.2mm character height, capable of handling a wide range of input currents including 0β5A, 0β2.5A, 0β1A, and even low currents like 0β50mA. The device supports both AVG (Average) and RMS (Root Mean Square) measurement modes, enabling precise readings regardless of signal type. It operates on a standard 100β240VAC 50/60Hz power supply and uses a ΣΠ(Sigma-Delta) ADC for stable 16.6ms sampling. The main output relay (LO) is ideal for triggering alarms or control functions based on low threshold values, while the sub output provides real-time PV transmission (DC 4β20mA) to external systems, ensuring seamless integration with PLCs and monitoring devices.
Engineered for durability, the MT4Y-AA-43 includes IP56 front panel protection and is rated for -10Β°C to 50Β°C ambient temperatures with humidity resistance up to 85% RH. Its double insulation and 1kV dielectric strength between measurement and power circuits ensure operational safety in electrically demanding environments. The display accuracy is maintained at Β±0.3% F.S. Β±3 digits under normal temperatures and remains reliable even in challenging industrial settings. The built-in external hold function allows readings to be frozen during inspections or calibration. Compact in size with a packaged weight of approximately 213.5g, this meter is designed to fit modern industrial control panels without compromising space or functionality.
The Autonics MT4Y-AA-43 is widely used in control panels for motor monitoring, load analysis, machine diagnostics, and energy audits. Industrial maintenance engineers trust this model to detect fluctuations in equipment current, helping them prevent overloads and reduce downtime. Its real-time PV transmission feature makes it suitable for integration with SCADA or PLC-based automation systems in industries like manufacturing, utilities, and process control. Students and junior engineers also use this model in lab settings to understand real-time current behavior and analog signal conversion. Whether you're managing a production line or teaching the next generation of engineers, the MT4Y-AA-43 offers both the precision and practical features needed to meet demanding application needs.
