STV Electronic announces two new, even more compact variants of its Raspberry Pi-based 64-bit DIN rail PC family for control cabinets: the Smart Manager Basic and the Smart Manager Light. Both are available immediately, which is important to emphasize given today’s supply chain challenges. Based on the 1.2 GHz Broadcom® BCM 2837 quad-core processor, the new systems have no front interfaces, which allows for installation in extremely slim spaces.

Thanks to their shallow depth of 62.2 mm, compact width of 6HP (108 mm) and top/bottom interfaces, these industrial DIN rail PCs fit into any control cabinet – even flush-mounted small distribution boxes that permit maximum installation depths of up to 70 mm in accordance with DIN 43880. The new DIN rail PCs can be used in a variety of edge computing applications in building automation and industrial control.

Featuring 1 GB LPDDR2 SDRAM and between 8 or 32 GB eMMC onboard flash memory, the real-time capable systems provide an HDMI interface, up to two Ethernet ports, four USB 2.0 ports and two programmable RS-485 interfaces. Further interfaces – including WLAN, fieldbuses such as M-Bus, Modbus, LonWorks and KNX, as well as digital, analog and custom I/Os – are easily added to the Smart Manager Basic using wireless expansion modules.

A wide voltage input range of 12 to 30 V facilitates the integration of industrial applications. Based on Debian Linux, the Smart Manager Basic and Light supports a wide choice of programming software: CoDeSys, NodeRed, Node.js, C or C++ offer solutions for all application areas. FHEM, openHAB or Mosquitto can also be easily installed.

The new Smart Manager Basic and Light are offered with long-term availability of at least ten years. This includes continuous provision of the latest security patches, which is crucial for open source solutions in building automation and industrial control.
