Industrial 4G LTE IoT Gateway
M331-IG
Proscend Industrial IoT Gateway M331-IG, offering high security and performance, is designed to collect data from industrial automation devices such as PLCs, sensors, servos, HVAC systems, and water pumps. These field data are encrypted and transmitted to remote locations via VPN tunnels over 4G/3G cellular networks. Hence, administrators at a central control center can build their own HTTPS and/or MQTT servers to process and analyze data from a large number of M331-IG IoT gateways, and remotely control the industrial automation devices behind one or more designated M331-IG gateways.
Efficient End-to-End IoT Solution
Proscend Industrial IoT Gateway M331-IG perfectly comes with the O'smart SDn IoT software platform, leveraging the unique "Supervisor Defined nodes" value. This combination allows IoT operators to actively tailor nodes according to specific requirements and manage scalable IoT networks remotely.
Excellent Industrial-grade Design
Proscend Industrial IoT Gateway M331-IG offers 3 Gigabit LAN ports, 1 Gigabit WAN port, and dual SIM support for critical applications and reliable connectivity. With its rugged, compact design for DIN-rail or wall mounting in tight spaces, the M331-IG includes digital I/O, RS-232, RS-485, DC and AC power inputs for flexible installation in demanding environments.
