Neousys IGT-31D Arm Cortex-A8 Sitara AM3352 DIN-Rail IoT Gateway with Isolated CAN Bus and PoE PD

CAN bus carries the data on drives, battery systems and many machines, and a small gateway with its own network link is often the simplest way to reach it. The Neousys IGT-31D is an IoT gateway with an isolated CAN 2.0 A/B port, two 10/100 LAN ports and a PoE+ powered device input, so one network cable can power it. It is the CAN bus version of the IGT-30 series.

It runs a Texas Instruments Sitara AM3352, a single Arm Cortex-A8 core at 1 GHz, with 1 GB of DDR3L memory and Debian 9 pre-installed, which suits CAN decoding, filtering and forwarding at the edge. Two microSDHC slots, one external and one internal, keep the system image and user data apart, and Neousys lists the IGT-31D as Microsoft Azure and AWS Greengrass certified for IoT.

Besides the CAN port, the IGT-31D has eight isolated digital inputs for dry contact, sinking or sourcing signals at 3750 Vrms isolation, two isolated digital outputs rated at 500 mA and 24 V, a software-configurable RS-232/422/485 port, a USB 2.0 port and an RS-232 console port. A full-size mini PCIe socket with an internal SIM slot takes a 3G, 4G or Wi-Fi module, so CAN data can travel over a cellular link, and the unit also takes 12 to 25 V DC where PoE is not available.

The IoT gateway runs from -25 °C to 70 °C, with a wide temperature microSD card needed below 0 °C, is rated for 5 Grms vibration and 50 Grms shock, and meets CE and FCC Class A to EN 55032 and EN 55024, in a 43 x 77 x 104 mm DIN-rail case. The IGT-30D is the same gateway without CAN, and the IGT-34C reads four 4 to 20 mA current loops instead.
