TELTONIKA Industrie GPIO LTE Gateway Board, Digital I/O, USB, RMS Support

The TELTONIKA TRB141 is a versatile industrial gateway designed for remote monitoring and control applications. It features configurable digital inputs (DI1/DI2) supporting both DRY and WET contact modes, with WET mode detecting 0-1.9V as logical '0' and 1.9-3.8V as '1', while DRY mode uses short-to-ground detection. The device includes a 4-20mA analog input for sensor connectivity and provides isolated power outputs including a direct power output for external sensors and a dedicated 3.8V output for 1-Wire sensors. With dual relays (one non-latching, one latching) supporting various voltage and current ratings, the TRB141 enables robust control capabilities. It offers comprehensive mobile connectivity with 4G LTE Cat 1 (up to 10Mbps), 3G (up to 42Mbps), and 2G (up to 236.8kbps) support, along with industrial protocols including TCP/IP, MQTT, and SNMP for seamless integration into industrial IoT systems.
