The Autonics MT4Y-DA-40 is engineered for accurate DC current measurement across ranges such as 0β5A, 0β2A, 0β500mA, 0β200mA, 0β50mA, 4β20mA, 0β5mA, and 0β2mA. Its 4-digit 7-segment LED display with a 14.2mm character height ensures excellent visibility in panel environments, even under low-light or high-vibration conditions. The wide display range of -1999 to 9999 provides flexibility for diverse current monitoring applications.
Powered by a 100β240VAC 50/60Hz supply, the MT4Y-DA-40 uses a Sigma-Delta ADC with a 50ms sampling cycle to deliver stable and real-time measurement. Accuracy is maintained at Β±0.1% F.S. Β±2 digits under standard temperature conditions, and Β±0.5% F.S. across extended industrial ranges from -10Β°C to 50Β°C. Safety is ensured with double insulation and 1kV dielectric strength between input and power sections, while the IP56-rated front panel provides protection against dust and moisture. An external hold function supports calibration and inspection by freezing real-time data when required.
The MT4Y-DA-40 Digital Panel Meter is widely used in factory automation, electrical control panels, and industrial testing stations where accurate current measurement is critical. Its relay outputs (HI, GO, LO) allow engineers to connect alarms or automated switching systems for safety and operational efficiency.
Maintenance engineers rely on its readability and stability during inspections, while automation specialists integrate it into PLC and SCADA systems for current loop monitoring. Its compact size (~134g) makes it suitable for dense control cabinets, while durability and safety compliance ensure long-term reliability. In technical institutes and training labs, the MT4Y-DA-40 is also valued as a teaching tool for understanding analog signaling, current loops, and instrumentation. Backed by Autonics engineering, this model balances accuracy, ease of use, and resilience for industrial and educational environments alike.
