MD09C Loop Powered Display (4–20mA Loop Indicator)

Q: Does the MD09C need a power supply?

No. It is powered entirely by the 4-20mA loop and adds at most 2.7 V of voltage drop, so it can be inserted into most existing loops.

Q: What signals can it display?

Any 4-20mA transmitter signal — flow, level, temperature, pressure — scaled to engineering units, current, voltage or percent.

Q: Can it be used in hazardous areas?

An intrinsically safe display version is available for reading transmitter outputs inside hazardous areas.

MD09C Loop Powered Display (4–20mA Loop Indicator)

Loop-powered 4–20mA display that needs no extra power supply: remote indication of flow, level, temperature and pressure signals with ±0.1% accuracy and <=2.7 V drop.

Key Specifications

Model: MD09C
Principle: Loop-powered digital indicator
Size / Connection: Panel / field mounting
Measuring range: Input 4–20mA loop; operating current 3.5–25 mA
Accuracy: ±0.1%
Output / Protocol: Display only — units for flow, level, temperature, pressure, current, voltage, percent

The MD09C loop display shows transmitter signals exactly where operators need them — at the tank, reactor or pipeline — without any additional power supply. It draws its energy from the 4-20mA loop itself and adds no more than 2.7 V of loop drop.

Resolution is 1/99,999 with ±0.1% accuracy and 10 readings per second. Display units cover flow, level, temperature, pressure, current, voltage and percent, and an intrinsically safe version allows reading in hazardous areas.
