RTU- Remote Terminal Unit


The RTU (Remote Terminal Unit) is a data processing unit that operates with battery, equipped with two-way communication radio frequency, ready to be wired to almost any device or endpoint element in a network that is capable of issue a pulse signal, such as; Water meters, gas or electricity; Valve or solenoid-operated switch; Sensors or detection devices.
The processing unit RTU data supports almost all connection interfaces pulse or RS232 / 485, are water meters, gas or electric power and other interface devices. In addition, the unit: Processes all raw data; Packaged and processed data stored in its data logger; Implements and monitors the signals received from the application.
The two-way wireless connectivity RTU allows data communication with the Base Station Unit (BSU), which in turn binds to the application server through a public network through a service provider for data transmission. The unit Transmits data processed to the server where the application resides; Receive and confirm the control signals received application.
The unit has autonomy of operation power supply through battery whose lifetime is 20 years. The RTU allows monitoring and remote control of a network of water, gas or electricity. It may be provided to connect to: A single endpoint. That is, one measuring apparatus; An individual endpoint with valve or switch. That is, equipped with a metering valve restriction service: O to 4 endpoints. That is, four measuring devices.
