Remote Terminal Unit (RTU) is a device located at a remote site to collect data and transmit the data back to a central station (or master). An RTU also collects information from the master device and implements processes that are directed by the master. RTUs are equipped with input channels for sensing or metering, output channels for control, indication or alarms and a communications port. RTU is usually part of the SCADA system.
