Each R-LITE system features two digital inputs, two analog/digital inputs, one digital output, and one RS232/RS485 connection, with other I/O options available (see the figure). Its internal quad-band GSM/GPRS modem, along with its user-friendly application software, allows maintenance and configuration to be performed locally, via cable, or remotely via cell phone or modem.

Typical applications include powerline communications, control and management, security, energy and fluid transport (water, fuel, sewage, etc.), homeland security, theft alerts, control communication, automatic meter reading (AMR), alternative energy, generators, climate and temperature control, weather stations, and wind turbines.

The R-LITE can be used as a standalone unit either with direct inputs or connected to a PLC programmable logic controller (PLC) for controlling the PLC’s I/O lines and registers. Also, the R- LITE is a versatile communication tool for PLCs supporting Modbus, Unitronics, Hostlink, and many other serial communication protocols. It can serve as a cellular gateway for a PLC, enabling complete, interactive, mobile phone control and communication or for just downloading stored data files.

With R-LITE Web, remote devices and sensors can be directly measured via GSM/GPRS, with the logged data sent straight to a secure Web browser.

The supplied human machine interface (HMI) software is designed to support many application areas and can be tailored specifically to the project needs.
