Revolution Pi: the compact industrial PC for various applications

Revolution Pi is an open, modular and cost-effective industrial PC based on the well-known Raspberry Pi, which complies with the EN61131-2 standard. Equipped with the Raspberry Pi Compute Module, the individual base modules can be quickly and easily expanded with a variety of suitable digital and analog I/O modules as well as fieldbus gateways, depending on requirements. Housed in a DIN rail housing, the three available base modules RevPi Core, RevPi Core 3 and RevPi Connect already have USB, Ethernet and HDMI connections. The basic and expansion modules are supplied with the 24 volts common in industry. Whether compact industrial PC, small industrial controller or intelligent (I)IoT gateway, the Revolution Pi can be used for a large number of applications thanks to its flexible design.

Open Source now also in the automation industry

In addition to the disclosure of circuit diagrams, the open source concept of the Revolution Pi is also consistently continued with the software. An adapted version of the Raspbian operating system known from Raspberry Pi, including the drivers for the numerous expansion modules and a real-time patch, is pre-installed ex works. The use of Raspbian ensures that software or applications running on a Raspberry Pi will always work on the Revolution Pi. Full root access allows the software to be fully customized to your needs. Important (I)IoT protocols such as MQTT and OPC UA can be easily integrated. Individual applications can be programmed with Node-RED, Python or directly in C, among others. For users who prefer ready-to-use software solutions, cost-effective and powerful control and SCADA software can be purchased at a later date. Thus Revolution Pi can be extended to a real industrial small controller.

Flexibly combinable, depending on the application

The Revolution Pi System has a modular design and can be equipped with a wide variety of extension modules depending on the application. The expansion modules are simply connected to the base module via the top connector. Depending on the basic module, up to 10 expansion modules can be connected to one basic module.

Three different digital input or output modules with up to 16 digital inputs or outputs are available. The RevPi AIO analog expansion module has both inputs and outputs for current and voltage. In addition, the module has two separate inputs for connecting PT100/1000 temperature sensors. The Revolution Pi system can be integrated into an industrial network such as PROFINET, EtherCAT or PROFIBUS with the help of gateway expansion modules.
