Easy and Low-Cost Measurement
1
■Simple Measurement/Installation
The built-in LCD screen enables the settings, measurements, and displays required for
measuring energy with a single unit.
■Product Lineup that Provides Easy Equipment Selection
This measuring unit lineup consists of a "High Performance Model" and a "Standard Model".
①
High Performance Model: For customers who want to perform harmonic measurements, alarm monitoring,
upper/lower limits monitoring, alarm output and pulse input/output, in addition to the Standard Model features
②
Standard Model: For customers who "want to start measuring energy in a simple and low-cost manner".
■Specialized Cable is Not Required
You can use a general-purpose cable between the measuring unit and split current sensor!
Cost can be reduced because no specialized cable is required.
* EMU2-CB-Q5B(-4W) is necessary if using a split 5A current sensor.
* Refer to “Wiring Precautions” on p. 26 for information about general-purpose cables.

■Logging Unit
Use of a logging unit allows you to output various energy (such as current, voltage and power) data measured
using the energy measuring unit in CSV file format on an SD memory card for easy data management.
■Communication Unit (CC-Link Communication Unit)
A communication unit can be connected to the system using CC-Link communication.

*1: Data Acquisition Software (EMU4-SW1) can be downloaded for free from the Mitsubishi Electric website.
*2: A sample GOT screen can be downloaded for free from the Mitsubishi Electric website. (GT14**-Q, GT1030)
*1: The data retention period of the logging unit is limited.
*2: It is necessary to always specify logging ID when collecting measurement data from multiple logging units on a single SD memory card.
Refer to the operation manual for details.
*3: Units compatible with each communication method are necessary if connecting a PLC.
