Second-generation Raspberry Pi-based DIN rail PCs fit any control cabinet

STV Electronic offers 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. They are available immediately. Based on the 1.2GHz Broadcom BCM 2837 quad-core processor, the new systems have no front interfaces, which provides for installation in very slim spaces. Due to their shallow depth of only 62.2mm, compact width of 6HP (108mm) and top/bottom interfaces, these industrial DIN rail PCs fit into any control cabinet – even flush-mounted small distribution boxes that allow maximum installation depths of up to 70mm in accordance with DIN 43880. The new DIN rail PCs may be employed in various edge computing applications in building automation and industrial control.

Providing 1GB LPDDR2 SDRAM and between 8GB or 32GB eMMC onboard flash memory, the real-time capable systems offer an HDMI interface, up to two Ethernet ports, four USB 2.0 ports and two programmable RS-485 interfaces. Additional interfaces – including WLAN, fieldbuses such as M-Bus, Modbus, LonWorks and KNX, and digital, analog and custom I/Os – are readily added to the Smart Manager Basic utilising wireless expansion modules. A broad voltage input range of 12V to 30V aids the integration of industrial applications. Based on Debian Linux, the Smart Manager Basic and Light supports a wide selection of programming software: CoDeSys, NodeRed, Node.js, C or C++ provide solutions for all application areas. FHEM, openHAB or Mosquitto can also be readily installed.

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

Custom-label housings, embedded variants, and individual I/O designs are obtainable on demand. Where needed, the company also supports OEM customers, system integrators and large end-users in the design of specific control logic.
