What is an industrial voltage and current data logger?
An industrial voltage and current data logger continuously measures electrical parameters like AC/DC voltage, 4-20mA loop signals, CT load currents, and calculated active power (kW/kWh), storing every reading with a verified timestamp.
The AIOTHUB logger adds what plant electrical teams need on top: real-time alerts the moment currents spike or voltage sags beyond safe bounds, local SD buffering that records through network outages, and Modbus/MQTT for immediate SCADA and ISO 50001 energy monitoring integration.
It provides an audit-ready, low-cost way to detect motor overloads, balance phases, monitor process transmitters, and cut peak demand penalties.

How to Choose the Right Voltage & Current Data Logger
Six factors separate a logger that safely protects your electrical equipment from one that fails during audit reviews.
Input signal compatibility
Identify whether you need 4-20mA process loop logging, 0-10V analog voltage, or non-invasive AC/DC current transformers (CTs).
True RMS calculation
Ensure the device calculates True RMS to accurately measure distorted or non-linear loads created by VFDs and power electronics.
High galvanic isolation
Verify high galvanic isolation (2.5 kV RMS) between high-voltage inputs and communication buses to prevent equipment damage.
Sampling speed & inrush
Fast sampling rates down to 1 second are essential to capture motor start inrush spikes and transient voltage sags.
Connectivity & SCADA
Select loggers supporting Modbus RTU/TCP, MQTT, and OPC-UA for drop-in integration into energy management and PLC systems.
Memory buffer & backup
Ensure on-board SD buffering and battery backup so plant power interruptions cause zero loss of electrical telemetry records.
