Overview

The Advantech SmartFlex SR310 (BB-SR31000120) is an industrial LTE Cat 4 cellular router that connects remote devices and LANs, or provides automatic cellular failover for wired networks. This configuration has two independent 10/100 Ethernet ports plus a 3-port Ethernet switch, for five RJ45 ports in total. It also has dual SIM slots, GNSS, digital I/O and a metal DIN-rail enclosure rated from -40 to +75 °C. The radio carries AT&T, T-Mobile and Verizon carrier approvals.

  • LTE Cat 4 up to 150 Mbps DL / 50 Mbps UL with HSPA+/UMTS and EDGE/GPRS fallback
  • Dual Mini SIM (2FF) slots for failover to an alternate provider; AT&T, T-Mobile and Verizon carrier approval
  • 2× isolated 10/100 Ethernet ports plus a 3-port Ethernet switch (5 RJ45 ports total)
  • Onboard GNSS receiver: GPS, GLONASS, BeiDou, Galileo
  • 2 digital inputs, 1 digital output, USB 2.0 host and microSD slot
  • Metal DIN-rail enclosure, -40 to +75 °C operation, 10–60 V DC input
  • Linux-based ICR-OS with Python, C/C++, Node-RED, Router Apps and WebAccess/DMP management
  • Keeps remote equipment online with dual-SIM failover and automatic cellular backup for wired links

The Advantech SmartFlex SR310 is a DIN-rail cellular router for industrial and remote sites. It suits industrial PCs, HMIs, traffic controllers, kiosks, meters and cameras, and it can act as an automatic wireless failover for a wired WAN. LTE Cat 4 delivers up to 150 Mbps down and 50 Mbps up, which is enough for video transmission. The router falls back to HSPA+/UMTS and EDGE/GPRS. Two Mini SIM (2FF) slots allow failover to an alternate provider, and the unit carries AT&T, T-Mobile and Verizon carrier approvals.

Order code BB-SR31000120 is the no-Wi-Fi, no-PoE build in a metal enclosure. It has 2× Ethernet 10/100 ports and an additional 3-port 10/100 Ethernet switch, all with 1.5 kV isolation. Other built-in interfaces include: • 1× USB 2.0 host port and a microSD slot • 2 digital inputs and 1 digital output • A battery-backed RTC and a hardware watchdog • An onboard GNSS receiver (GPS, GLONASS, BeiDou, Galileo)

The router accepts 10–60 V DC, draws 4 W on average and offers a 10 mW sleep mode.

An ARM Cortex-A8 at 1 GHz with 512 MB RAM runs ICR-OS, a Linux-based operating system. You can build applications in Python, C/C++, BASH or Node-RED, and Router Apps add Modbus, DNP3, IEC 60870-5-101/104, MQTT and cloud IoT platform support. Networking and security features include: • VPN: WireGuard, OpenVPN, IPsec (IKEv1/IKEv2), GRE and L2TP • Routing: BGP and OSPF via Router App, plus VRRP • Authentication: RADIUS, TACACS+ and 2FA

Fleets can be deployed and monitored with WebAccess/DMP.

The package includes a metal DIN rail clip (BB-SBD40) and a 3 m 2-wire power cable (BB-KN-v3-MO2-3). Antennas and a power supply are sold separately. The Advantech SR310 datasheet is available for this model.

Ideal for

  • Cellular primary or failover WAN for industrial PCs, HMIs and control cabinets
  • Remote connectivity for traffic controllers, kiosks, meters and roadside equipment
  • Video transmission from cameras at sites without wired broadband
  • Edge IoT gateway converting Modbus/DNP3 data to MQTT or cloud platforms
  • Mass-deployed remote sites managed centrally with WebAccess/DMP
