Features
●This product, EcoMonitorPlus, is a unit with building block method.
The basic unit in combination with one option unit and/or maximum three extension units can provide various applications.
●The contact output/analog output controls the load of equipment or devices.
●The communication function (MODBUS RTU, CC-Link, or CC-Link IE Field Network Basic) enables to transmit the control
information to superior monitoring systems.
*When a communication function other than MODBUS RTU is used, the appropriate option unit is required.
●Integrating the measuring and control functions easily enables energy saving control.
*This unit does not have any measuring function. Combining with the appropriate extension unit enables the integration of
measuring and control functions.
●Writing some settings with Control Unit Engineering Tool (Model: EMU4-KNET) enables this unit to execute the control.
Control Unit Engineering Tool can be downloaded for free from the Mitsubishi FA Global site.
●This unit comes with a version upgrade function for supporting new functions.
It can be updated to the latest version by using Control Unit Engineering Tool (Model: EMU4-KNET).
