includes full Linux OS customization, comprehensive software and integration support, as well as continuously updated security patches. This makes our industrial open source solution extremely attractive for many edge computing tasks in building automation and industrial control technology, especially since we support all common interfaces and will also continuously add new expansion modules to our range,” said Markus Hühn, Managing Director of STV Electronic.

In the currently available multi-threaded quad-core design, the Raspberry Pi based DIN rail PC Smart Manager 4.0 features a 1.2 GHz Broadcom® BCM2837B0 processor. Next to the new I/O expansion option, up to 2x Ethernet, 6x USB 2.0 and 2 galvanically isolated deterministic serial RS‑485 interfaces are provided as standard.

To connect the I/O Module 16, only one of the two interfaces is needed, while the other can also be designed for RS‑232. The DIN rail PC further offers an expansion bus, which can be used to connect customer-specific extensions such as WLAN, field buses such as M-Bus, Modbus or LonWorks, as well as other external I/Os. For on-site visualization functions, 1x HDMI is also supported. With an input voltage of 12-30 V, a real-time clock with a minimum 24‑hour battery buffer, and an environmental temperature tolerance from -40°C to +55°C, the embedded Linux based DIN rail PC can be integrated into a wide range of industrial applications.

The I/O Module 16 for the Raspberry Pi based DIN rail PC Smart Manager 4.0 is available immediately. Custom-labelled housings, embedded variants, and individual I/O configurations are available on request as well.

STV Electronic also helps OEM customers, system integrators and large end users with the design of specific control logic if required. Users can choose between real-time programming environments like CoDeSys, IoT development tools like NodeRed, web server technologies like Node.js or ‘classic’ C and C++ code, as well as many other solutions from the huge Raspberry Pi community. Solutions for building and home automation like FHEM or openHAB, as well as
