Janztec has launched an embedded controller based on the Raspberry Pi 2, adding a 24-pin expansion connector with CAN, RS232/485, and industrial I/O.



The emPC-A/RPI follows in a long line of emPC-branded industrial computers dating back to the Xenomai Linux supported emPC-M from 2008 when Germany-based Janztec went by the name Janz Automationssysteme AG. Janztec continues to sell products in the U.S. via Saelig, which is shipping the emPC-A/RPI for $309. The price goes to $364 if you add a microSD card loaded with Raspbian Linux for the computer’s quad-core, 900MHz Raspberry Pi 2 Model B mainboard.

This is not the first Raspberry Pi 2 based mini-PC — others include the Zymbit Orange — but it’s the first we’ve seen that’s billed as an industrial embedded controller, and the first to offer a CANbus interface. The CAN link is available via the emPC-A/RPI’s hard-to-miss, orange and green colored, 24-pin multi-connector on the side of the box. The expansion connector also offers SPI, I2C, DIO, USB, and RS232/485.

Janztec supplies drivers for the CAN and RS232/485 interfaces, as well as the computer’s battery-backed real-time clock. These features are also supported by the CODESYS soft-PLC runtime control system software.

The emPC-A/RPI provides the Pi 2’s 1GB of RAM and microSD slot, as well as an exposed HDMI port, a Fast Ethernet port, and four USB 2.0 ports. A serial debug console port is also available.

The 4.0 x 3.8 x 1.2-inch embedded controller is wall- or DIN-rail mountable, and supports 0 to 45°C temperatures. The system runs on a wide-range 9-32 VDC power supply.
