Industrial IoT connectivity across utilities, automation, smart city, transport and more.
The TRB series covers single-device connectivity from low-power NB-IoT sensors to high-throughput 5G backhaul. The right model depends on the interface your equipment needs, the data rate required and the environment. Here are the most common application areas.
Gas, water, electricity and heat meters. M-Bus concentrators with the TRB143. NB-IoT at 450 MHz with the TRB256 for basement and remote meter installations. DNP3 and DLMS for SCADA-connected infrastructure.
PLCs, variable speed drives and industrial controllers over Modbus RTU via the TRB145 or TRB246. OPC UA integration with the TRB160. 5G low-latency control with the TRB501.
Street lighting control, traffic sensors, environmental monitoring and public Wi-Fi backhaul. Compact TRB140 or TRB160 for single-device installations in street furniture cabinets.
Bus and fleet telematics using the TRB246’s GPS. Data loggers with RS232 or RS485 interfaces. Ticketing and passenger information systems with TRB140 LTE backhaul.
LTE backup for payment terminals and EPOS systems. TRB140 as a silent failover device – activates automatically when the fixed line drops. No customer impact.
Remote site monitoring with dual SIM coverage. TRB246 for sites where two operators give better coverage. TRB256 NB-IoT for low-power field sensors in areas with marginal 4G signal.
IP alarm transmission and CCTV backhaul. The TRB140 is widely used as a primary or backup path for intruder and fire alarm communicators.
Temporary site offices and welfare facilities. The wide 9-30V power range handles generator and site distribution power. Compact units fit inside standard enclosures.
Medical devices with RS232 serial outputs use the TRB142 for cellular data transmission. TRB501 for high-bandwidth medical imaging or video consultation infrastructure.
The TRB143 with its M-Bus interface is designed specifically for district heating networks. Read multiple heat meters per building and forward consumption to the billing system over LTE.
OCPP protocol over cellular for EV chargers in car parks, motorway services and retail sites. TRB140 provides the LTE backhaul for OCPP-compliant charge point management systems.
High-throughput 5G backhaul for 4K content delivery. The TRB501’s 2.5 Gbps Ethernet and Release 16 5G handles demanding content distribution workloads.
