Neousys IGT-21 TI Sitara AM3352 DIN-Rail Industrial IoT Gateway with Isolated CAN Bus and DIO

Drives, battery systems and many machines report their state over CAN bus, and getting that data to a server usually takes a small gateway with a modem. The Neousys IGT-21 is an industrial IoT gateway with an isolated CAN 2.0 A/B port for that job, shipped with Debian 8 pre-installed in a 41 x 77 x 104 mm case that mounts on a DIN rail. It is the CAN bus version of the IGT-20 series.

It runs a Texas Instruments Sitara AM3352, a single Arm Cortex-A8 core at 1 GHz, with 1 GB of DDR3L memory, which suits CAN decoding, filtering and forwarding. Two microSDHC slots, one external and one internal, keep the system image and user data apart. A full-size mini PCIe socket with an external SIM socket takes a 3G, 4G or Wi-Fi module, so CAN data can be sent straight over a cellular link, and Neousys lists the IGT-21 as Microsoft Azure and AWS Greengrass certified for IoT.

Besides the CAN port, the IGT-21 has four isolated digital inputs and four isolated digital outputs at 2500 Vrms isolation, two software-configurable RS-232/422/485 ports, a 10/100 Ethernet port, a USB 2.0 port and a three-wire RS-232 console port. Six user-programmable LEDs and two user buttons cover status and local control.

Power is 8 to 25 V DC on a terminal block, and the industrial IoT gateway runs from -25 °C to 70 °C, with a wide temperature microSD card needed below 0 °C. The IGT-21 is rated for 5 Grms vibration and 50 Grms shock, with CE and FCC Class A compliance to EN 55032. The IGT-20 is the same gateway without CAN, and the IGT-22 offers eight isolated inputs and outputs.
