MCU
Master Controller Unit

MCU series is a small and compact industrial controller based on a 32-bit 216 MHz ARM CPU. With
user-friendly software and hardware, the user can keep application development quick and simplified.
MCU can take almost any role in remote utility applications such as solar power plants and electricity
distribution substations. It combines GPRS/GSM modem, digital inputs, outputs and datalogger in a single
device.Device with built-in 2 digital inputs and outputs and has ethernet and serial communication ports
for flexible connectivity to SCADA, field devices and remote control systems.
