The Autonics MT4Y-AV-4N Digital Panel Meter from the MT4Y Series reasserts its role as a dedicated AC voltage and frequency indicator for industrial control systems. Offering input ranges from 0–500V down to 0–1V, selectable AVG/RMS measurement modes, and a 100–240VAC power supply, the MT4Y-AV-4N provides accurate AC monitoring with a bright 4-digit, 14.2mm 7-segment LED display. The meter delivers dependable measurement accuracy (specified per ambient conditions), a rapid 16.6ms sampling cycle, and robust IP56 front protection, making it suitable for harsh factory environments where visible realtime voltage and frequency feedback matter.
In practical application, the MT4Y-AV-4N Panel Meter is used across power distribution panels, motor control centers, process control cabinets, and energy monitoring systems. In power management it displays RMS/AVG voltages and line frequency for fault detection and preventive maintenance; in motor control and conveyor systems it provides rapid frequency readout for loop tuning and speed verification. The selectable display cycle and quick sampling make the meter well suited to both steady-state monitoring and dynamic process checks, improving operator response time and supporting integration with PLC logic and alarm thresholds.
Manufactured by Autonics Corporation, the MT4Y-AV-4N benefits from the company’s long-standing quality controls and ISO-oriented production practices. The product is engineered with reinforced insulation between measurement and power sections and a Sigma-Delta ADC for stable low-noise conversion, ensuring measurement fidelity in industrial conditions. Autonics’ regional distribution and technical support in India provide local engineering assistance, calibration guidance, and spare part availability — factors that reinforce reliability and total cost of ownership for OEMs and maintenance teams.
For system designers choosing an I/O configuration, the MT4Y Series includes close variants that retain the same mechanical footprint and display usability while changing outputs and I/O focus. If analog PV transmission or analog loop output is required, consider the MT4Y-AV-4N (AC voltage, Frequency). For AC current monitoring needs, the MT4Y-AA-4N provides multiple AC current ranges and frequency measurement while retaining the same display and protection level. Both variants keep the same IP56 front protection and fast sampling characteristics, enabling straightforward substitution based on signal type and communication requirements.
Summary: the Autonics MT4Y-AV-4N AC Voltage & Frequency Panel Meter from the MT4Y Series provides fast, visible, and accurate AC measurement across broad voltage ranges (0–500V), with RMS/AVG processing, a 16.6ms sampling cycle, and IP56 front protection for industrial environments. Backed by Autonics Corporation’s engineering and local support presence in India, the MT4Y-AV-4N simplifies integration into control panels, improves monitoring responsiveness, and supports maintenance strategies that rely on precise voltage and frequency readings.
