Overview
The Autonics MT4W is a 96 × 48 mm (1/8 DIN) digital panel meter for DC or AC voltage and current, with multiple ranges selectable by DIP switch and a 4-digit display scalable to engineering units. The -DA model measures DC current (including 4–20 mA from any transmitter), the -DV model DC voltage and the -AA/-AV models AC. Two NO relay outputs (HI/LO) provide alarms, and options add RS-485 Modbus RTU communication and an isolated 4–20 mA or 0–10 V retransmission output. Display scaling, decimal point and hysteresis are set from the front keys, which makes the MT4W a quick way to display and alarm a transmitter signal without a PLC.
Key features
- Measures DC/AC voltage and current, multi-range by DIP switch; 4-digit scalable display
- Accuracy ±0.1 % FS (DC), ±0.3 % (AC); display range -1999 to 9999
- Two NO relay outputs (HI/LO) with hysteresis and delay
- Options: RS-485 Modbus RTU, 4–20 mA or 0–10 V retransmission, NPN/PNP outputs
- 96 × 48 mm, 100–240 V AC supply; IP65 front
Typical applications
- Displaying 4–20 mA pressure, level or flow signals on a panel
- Motor and heater current monitoring
- DC voltage and current on battery and PV systems
- Simple HI/LO alarms without a PLC

Frequently asked questions
Can the MT4W display a 4–20 mA signal in engineering units?
Yes. The -DA model accepts 4–20 mA and scales it to any 4-digit value with decimal point, for example 0.0–100.0 % or 0–5000 L/h.
Can I retransmit the reading to a PLC?
With the retransmission option the meter outputs an isolated 4–20 mA or 0–10 V; with RS-485 the value is read over Modbus RTU.
Is the MT4W available from stock, and what is the lead time?
Standard -DA and -DV models are stocked in Vietnam with delivery in 1–3 days. We confirm with the quotation.
