Remote Terminal Unit

A remote terminal unit (RTU) is a multipurpose device used for remote monitoring and control of various devices and systems for automation.

A remote terminal unit is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

Other terms that may be used for RTU is remote telemetry unit or remote telecontrol unit.

Applications of RTU:

Remote monitoring of functions and instrumentation for:
Oil and gas (offshore platforms, onshore oil wells, pumpstations on pipelines)
Networks of pump stations (waste water collection, or for water supply)
Environmental monitoring systems (pollution, air quality, emissions monitoring)
Mine sites
Air traffic equipment such as navigation aids (DVOR, DME, ILS and GP)

Architecture contents:

Power supply
Digital (status) inputs
Analog inputs
