TRB256 is an industrial 4G LTE NB-IoT gateway designed for use in a wide range of IoT solutions. The device is equipped with multiple WAN interfaces, such as I/O, RS232, RS485 and an Ethernet port. Additionally, it has a dual-SIM function to ensure connection continuity. This industrial-grade gateway also supports the 450 MHz frequency band, which provides better LTE signal penetration compared to common frequencies, making the device an excellent choice for many different M2M applications.

Features

• CONNECTION: 4G/LTE Cat M1/Cat NB1, NB2/EGPRS
• 450 MHZ FREQUENCY BAND: Greater LTE signal coverage and better connection reach
• DUAL SIM: Automatic switch to backup connection, backup WAN and other switching scenarios
• INTERFACES: Ethernet, digital I/O, and serial interfaces (RS232, RS485) with 16-pin connector
