The Teltonika TRB141 is a compact industrial LTE Cat 1 gateway with digital, isolated and analogue inputs and relay outputs. It is designed for remote monitoring and control, where sensors, alarms and equipment need a simple mobile connection rather than a full router.

The defining capability of the TRB141 is turning local inputs and outputs into remote alerts and actions. A change on an input, such as a door contact or a 4-20 mA sensor reading, can trigger an email, SMS or RMS event, and the relay outputs can switch equipment on or off from a distance. LTE Cat 1 keeps power use and cost down while still providing a reliable link.
