D-Link DOM-311-TSO 4G LTE Industrial IoT RTU

Bring Remote Sensors Into a Connected Operation The DOM-311-TSO connects industrial sensors and control equipment through 4G LTE, combining a compact metal enclosure with practical remote administration. A single Nano-SIM connection, serial interface and digital I/O make it a focused terminal for field telemetry. Modbus and serial communications help link field devices to a monitoring platform without replacing the existing control equipment. LTE Cat 4 supports theoretical downloads up to 150 Mbps and uploads up to 50 Mbps. Actual service depends on mobile coverage, the operator, the SIM plan and installation. Highlights Cellular Connectivity 4G LTE Cat 4 up to 150 Mbps download and 50 Mbps upload. One Nano-SIM slot. Mobile service and an appropriate data plan are required separately. Equipment Connections 1 × Fast Ethernet ports. 1 × RS-232/RS-485 interface, 3 digital inputs and 2 digital outputs. Modbus TCP/RTU/ASCII and Virtual COM support. Industrial Installation −30°C to 70°C operating range. 9–36 V DC terminal-block input. Power adapter and DIN-rail kit included. Key Features Connect Field Signals to a Mobile Network A Fast Ethernet port, one selectable RS-232/RS-485 serial interface and digital I/O connect different field devices to one compact terminal. This suits remote monitoring installations where a standard office router cannot directly read the required industrial interfaces. Confirm signal voltage and wiring before commissioning. Translate Industrial Communications Modbus TCP, RTU and ASCII master/slave access supports integration with compatible controllers and telemetry equipment. Virtual COM offers TCP client, TCP server and UDP modes, while a RESTful API supports data interchange. Integration still requires matching register maps, protocols and application settings. Use Digital Inputs and Outputs Deliberately Three digital inputs accept the documented logic levels, and two open-collector digital outputs provide control signalling. These are not general mains-switching outputs. Use suitable interfacing and protection for the connected load, and have the control wiring reviewed against the installation requirements. Provide an OpenVPN Client Path The RTU supports an OpenVPN tunnel in client mode for a planned connection to a suitable remote VPN endpoint. This helps access field equipment without exposing every device directly to the public internet. The server, authentication material, routing and operator network requirements must be configured separately. Fit a Working Control Cabinet The metal enclosure, included DIN-rail kit and 9–36 V DC terminal input support cabinet installations. A −30°C to 70°C operating range is useful where normal desktop equipment would be unsuitable. Provide appropriate enclosure protection and ventilation; industrial temperature support does not establish an outdoor waterproof rating. Monitor and Maintain the Remote Terminal Web UI, CLI and command-script configuration support local administration, with SMS event management and network-status reporting for diagnostics. The included three-month D-ECS period supports central device management under its activation terms; continued service requires a paid licence. Apply supported firmware, controlled administrator access and a tested recovery plan for the installation. Summary The DOM-311-TSO is a practical field telemetry terminal for connecting equipment where a conventional office network is unavailable or needs a mobile alternative. Match the SIM service, radio bands, field interfaces and remote-management design to the installation for a system that is easier to deploy and maintain. Frequently Asked Questions Does It Include Mobile Data?ExpandCollapse No. A compatible active SIM and data plan are required separately. Check coverage, permitted bands, APN settings and any private-network requirements with the mobile operator. Can It Use Two Mobile Operators?ExpandCollapse This model has one Nano-SIM slot, so it does not provide dual-SIM failover. Does It Replace the VPN Server?ExpandCollapse This RTU provides an OpenVPN client. It needs a suitable server and a configured authentication and routing arrangement. Is It Waterproof for Outdoor Installation?ExpandCollapse No waterproof rating is claimed. The industrial operating-temperature range does not mean the connectors and enclosure can be exposed to rain. Use a suitable protected installation and follow the mounting instructions. Is D-ECS Management Included Permanently?ExpandCollapse The offer includes three months of D-ECS management under the applicable activation terms. Continued service requires the appropriate paid licence after that period. Local administration remains available. What Is Included for Installation?ExpandCollapse The standard package includes the device, cellular antennas, an Ethernet cable, power adapter and DIN-rail kit. Serial and digital-I/O terminal blocks are included; field equipment, signal wiring and an active SIM are separate. Baca selengkapnya
