The Energy Eye 300 PDM from MachineSens IoT is a digital panel meter for multi-phase energy monitoring. It measures voltage, current, power, frequency and harmonic distortion, accepts Rogowski coil or CT inputs, and connects over Modbus RS-485. It comes in Class 1 and Class 0.5S variants and feeds the BuildOT One platform.

| Current inputs | Rogowski coil or CT |
| Connectivity | Modbus RS-485 |
| Power | 220V AC |
| Mounting | Panel mounted |
| Variants | Class 1 and Class 0.5S |
| Platform | BuildOT One energy module |
Class 1 and Class 0.5S variants
| Variant | Standard | Accuracy class |
|---|---|---|
| Energy Eye 300 PDM Class 1 | IEC 62053-21/22 | Class 1 |
| Energy Eye 300 PDM Class 0.5S | IEC 62053-22 | Class 0.5S |
Both variants share the same measured parameters, inputs, connectivity, power supply and panel mounting. Pick the class that matches your reporting accuracy needs.
What the Energy Eye 300 PDM Digital Panel Meter does
- Monitors multi-phase loads. Cover main incomers, chillers, pumps and large distribution boards.
- Shows power quality. Frequency and harmonic distortion readings help spot problem loads.
- Takes flexible inputs. Use Rogowski coils for tight or large busbars, or CTs where they are already fitted.
- Fits a panel door. Panel mounting gives staff a local reading while data goes to the platform.
- Speaks Modbus. RS-485 links the meter to gateways and controllers.
Where it is used
Typical uses include main and sub-main metering in commercial towers, malls, hospitals, data rooms, hotels and campuses across the UAE and GCC. It suits large feeders where harmonics and power quality matter alongside energy use.
Works with BuildOT One
Data feeds the Energy and Utilities module for load profiles and consumption tracking, and the Measurement and Verification module for before and after comparisons.

Frequently asked questions
What is the difference between Class 1 and Class 0.5S?
They are two accuracy variants of the same meter. Class 1 follows IEC 62053-21/22 and Class 0.5S follows IEC 62053-22.
Which current sensors can I use?
Rogowski coils or current transformers.
How does it connect?
Over Modbus RS-485, typically to a MachineSens gateway that sends data to BuildOT One.
