The Autonics MT4Y Panel Meter delivers high-accuracy electrical signal indication, versatile mathematical display scaling, and isolated communication telemetry engineered specifically for industrial control panels, motor starter cabinets, generator monitoring consoles, and process automation enclosures.

Precision Process Indication with the Autonics MT4Y Panel Meter

Designed to provide clean, deterministic process visualization within space-constrained control cabinets, the Autonics MT4Y Panel Meter converts diverse electrical signals into real-world industrial units. Available in dedicated hardware variants for DC voltage, DC current, AC voltage, AC current, and line frequency, the instrument incorporates a high-performance analog-to-digital converter that maintains reading stability under noisy industrial environments.

The unit incorporates an intuitive parameter configuration interface that allows technicians to define high and low display limits directly. Through flexible decimal point positioning and display scale correction, incoming 4–20 mA, 1–5 V DC, or high-voltage AC inputs can be displayed proportionally as flow rates, vessel levels, line pressure, motor RPM, or total system amperage. The large 14.2 mm 7-segment red LED display provides parallax-free visibility across dimly lit switchrooms and long control room aisles.

Engineered for modular panel architectures, the meter supports interchangeable sub-output boards. Users can equip the device with triple relay alarm contacts, high-speed transistor outputs, 4–20 mA isolated retransmission for secondary PLCs, or an isolated RS-485 serial port communicating via open Modbus RTU protocol. Standardized within a compact DIN 72 × 36 mm housing, it delivers full-featured monitoring while occupying minimal vertical rack space.

Key Features and Engineering Advantages

• Versatile Display Prescaling: Translates raw electrical voltage, current, and frequency signals directly into meaningful physical engineering units from -1999 to 9999.
• High-Visibility LED Readout: Bright 14.2 mm red 7-segment digits ensure instantaneous legibility from broad angles across crowded factory floors.
• Comprehensive Peak Monitoring: Automatically captures and stores maximum and minimum process peaks to assist operators during post-fault root-cause analysis.
• Modular Sub-Output Architecture: Accommodates optional relay contacts, NPN/PNP open-collector alarms, 4–20 mA current transmission, or RS-485 serial telemetry.
• Compact Space-Saving Enclosure: DIN 72 × 36 mm front profile fits high-density multi-meter panel cutouts without sacrificing terminal clearance.

Industrial Applications and Process Integration

The Autonics MT4Y Panel Meter is implemented across diverse commercial distribution panels and factory automation skids, including:

• Main low-voltage switchboards and motor control centers (MCC) monitoring line current and voltage drops.
• Diesel generator control consoles tracking output alternator frequency, voltage, and phase balance.
• Industrial wastewater treatment dosing skids indicating tank level and pressure transmitter feedback.
• Conveyor speed monitoring and variable frequency drive tachometer feedback visualization.

Frequently Asked Questions

What is the primary difference between the Autonics MT4W and MT4Y series?
The difference lies in their physical DIN form factor. The MT4W uses a standard 1/8 DIN (96 × 48 mm) bezel, whereas the Autonics MT4Y Panel Meter uses a compact DIN 72 × 36 mm housing, offering a 50% smaller front panel footprint for high-density instrument rows.

How does the input scaling feature function on process current models?
The scale setup allows technicians to map the minimum and maximum input signals (such as 4 mA and 20 mA) directly to target display values (e.g., 0.0 to 100.0 bar or 0 to 5000 RPM). The meter then interpolates values linearly across the calibrated span.

Can the peak hold function be reset remotely?
Yes. Peak values (high and low records) can be cleared via front pushbutton navigation, by triggering an external digital hold/reset terminal input, or via Modbus register commands across the optional RS-485 serial interface.
