Remote terminal unit
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.〔Gordon R. Clarke, Deon Reynders, Edwin Wright,'' Practical modern SCADA protocols: DNP3, 60870.5 and related systems'' Newnes, 2004
ISBN 0-7506-5799-5 pages 19-21〕 Another term that may be used for RTU is remote telecontrol unit.
==Architecture==
A RTU monitors the field digital and analog parameters and transmits data to the Central Monitoring Station. It contains setup software to connect data input streams to data output streams, define communication protocols, and troubleshoot installation problems.
A RTU may consist of one complex circuit card consisting of various sections needed to do a custom fitted function or may consist of many circuit cards including CPU or processing with communications interface(s), and one or more of the following: (AI) analog input, (DI) digital input, (DO/CO) digital or control (relay) output, or (AO) analog output card(s).
