Red Lion’s Sixnet® series RAM® 6000 cellular RTUs with GPS and multi-carrier 4G LTE support, feature up to five Ethernet ports and a RS-232 serial port. 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 and communications for monitoring and controlling remote assets and processes in extreme conditions.

RAM 6000 cellular RTUs are available in 4G LTE with multi-carrier support and single-carrier 3G support. 4G LTE multi-carrier models feature the ability to change cellular carrier networks via software selection without the need to replace physical hardware. This gives customers the flexibility to choose from a host of carriers that serve different locations. In addition, with SMS Control there is no need to have an always-on connection; users can utilize SMS to do things like enabling VPN service for on-demand, secure communication.

Natively supporting Modbus, DNP3 and MQTT protocols, RAM 6000 industrial RTUs include digital and analog I/O. Built-in I/O helps to eliminate the need for external I/O to control applications. Red Lion's cellular RTUs are available with an optional split-LAN (WAN/LAN) architecture and features up to five 10/100Base-T(X) Ethernet ports. They also feature one RS-232 serial port supporting serial-to-IP conversion.
