Key Features

Versatile Input and Output Options

The MT4Y/MT4W series meters support various input types, including DC voltage, DC current, AC voltage, and AC current. Output options are just as diverse, featuring RS485 communication, low-speed serial output, BCD dynamic output, transmission output (DC 4-20 mA), NPN/PNP open collector outputs, and relay contact outputs. This flexibility allows these meters to be used in a broad range of applications, from industrial automation to energy management.

High Display Range and Accuracy

The meters can display measured values from -1999 to 9999, ensuring clear and accurate readings. With a display accuracy that varies slightly depending on the input type and ambient temperature, the MT4Y/MT4W series meters maintain precision in various conditions. The display uses a bright, easy-to-read 7-segment red LED, with character heights of 14.2 mm.

Advanced Measurement Capabilities

These digital panel meters are equipped with advanced measurement functions that include AC frequency measurement ranging from 0.1 to 9999 Hz, high/low-limit display scale functions, and peak value monitoring. These features make the MT4Y/MT4W series ideal for applications that require real-time monitoring and accurate control.

User-Friendly Adjustments and Corrections

To enhance usability, the MT4Y/MT4W meters offer zero-point adjustment and peak value correction. These features help users ensure that the measurements remain accurate over time and under different operating conditions. The PV transmission output (DC 4-20 mA) scale function further adds to the flexibility of these meters, allowing for seamless integration with other control systems.

Robust Power Supply Options

The MT4Y/MT4W series meters are designed to operate on various power supplies, including 12-24 VDC and 100-240 VAC, making them suitable for use in different industrial environments. Their robust design ensures reliable performance even in challenging conditions.

Communication Interface

The RS485 communication interface in these meters supports the Modbus RTU protocol, allowing for seamless integration into larger monitoring and control systems. The meters can be connected to up to 31 units over a distance of up to 800 meters, making them ideal for distributed systems.

Durability and Reliability

The MT4Y/MT4W series is built to last, with a mechanical life of over 20,000,000 operations and an electrical life of over 100,000 operations for the relay outputs. These meters are also resistant to vibration and shock, ensuring reliable operation in harsh environments.

Compact and Easy to Install

The MT4Y series meters are designed to fit into DIN W 96 x H 48 mm slots, while the MT4W series meters fit into smaller DIN W 72 x H 36 mm slots. This compact design, combined with their robust functionality, makes them an excellent choice for applications where space is at a premium.
