Red Lion's Sixnet series RAM 9000 high‑density I/O cellular RTUs with multi‑carrier 4G LTE support provide advanced control and communication in IIoT applications for remote assets and processes in extreme conditions. RAM 9000 industrial cellular RTUs seamlessly connect Modbus and DNP3 enabled SCADA equipment via software selectable multi‑carrier 4G LTE to remote networks or select Industrial Internet of Things (IIoT) Cloud platforms. Featuring a web‑based event engine that can trigger built‑in I/O or send SMS text messages based on real‑time operational data, RAM cellular RTUs can perform advanced control at the edge and alert personnel of critical events. A built‑in I/O concentrator allows the RAM to collect sensor data from on‑board I/O or connected devices. RAM RTUs can optimize cellular data consumption by optionally reporting only on an exception or only transmitting relevant data points saving time and money. With built‑in Ethernet, serial, digital and analog I/O and GPS, RAM RTUs easily integrate with existing equipment enabling remote monitoring and control for M2M applications in industries including oil and gas, water/wastewater, utility, transportation and mining.
