The Teltonika TRB141 is a compact 4G I/O gateway that pairs LTE Cat 1 cellular connectivity with a configurable GPIO connector block, letting you monitor and control field equipment such as pumps, alarms and gates over the mobile network. It runs the full RutOS operating system, giving it firewall and VPN features normally found in larger routers, while staying focused on I/O tasks rather than full routing. This makes it well suited to telemetry and SCADA deployments where a compact, dedicated I/O device is preferred over a full-featured router.

Product Features:

• Provides LTE Cat 1 cellular connectivity for remote data transfer over the mobile network.
• Includes a GPIO connector block with multiple configurable inputs and outputs for monitoring and controlling external equipment.
• Offers industrial DNP3 compatibility for integration with SCADA and telemetry systems.
• Has a micro-USB port for local configuration of the device.
• Runs RutOS with a full firewall and support for OpenVPN, IPsec and WireGuard VPN connections.
• Comes with free Teltonika RMS remote management, including a trial period, for monitoring and managing the device remotely.

Application Areas:

• Connecting PLCs, meters and serial equipment to the cloud.
• SCADA, telemetry and remote monitoring deployments.
• Compact installs where a full router would be more than the job needs.

Selection & Installation Notes:

• Choose the TRB141 when the job calls for I/O monitoring and control rather than multi-port routing, since it is built around the GPIO block rather than a full set of Ethernet ports.
• Check that the GPIO count and DNP3/Modbus protocol support match the equipment being connected before ordering.
