Graphite Edge Controller

Integrating communication and control

Integrating communication and control into factory automation and process control applications has never been easier. Red Lion’s Graphite® Edge Controller is a compact, highly scalable and rugged all-in-one industrial solution that reduces cost and complexity by combining IEC 61131 control capabilities with networking and data visualisation.

With all-metal construction, wide operating temperature and Red Lion’s Crimson® 3.0 software with Crimson Control functionality, the Graphite Edge controller operates in the harshest environments to provide a single programming solution for control, networking and data visualization. Simply use industry-standard IEC 61131 programming languages such as ladder logic, function block, structured text and instruction list to develop code much like a Programmable Logic Controller (PLC) or Remote Telemetry Unit (RTU) without the added expense of addition software. In addition, select from a variety of I/O, PID control and communications modules to connect, monitor and control a wide array of devices – regardless of location – to meet specific application requirements.

The Graphite Edge Controller also offers dual Ethernet ports, three serial ports, two USB host and USB device port along with SD card capability. In addition, it supports over 300 industrial protocols, provides data logging and remotely serves up graphical displays via a built-in web server.


  • Built-in industry-standard IEC 61131 control engine with ladder logic, function block, structured text and instruction list programming editors so there is no proprietary programming languages to learn
  • Rugged industrial design for deployment in harsh applications
  • Wide -40° to 70°C operating temperature
  • Easy configuration using Red Lion’s Crimson 3.0 software featuring Crimson Control so there is no need to buy any additional programming software or a separate controller
  • Powerful networking capabilities with built-in Ethernet and serial ports and support for over 300 industrial protocols with no additional licensing fees
  • UL/cUL and UL/cUL Hazardous approvals
  • Built-in data logging enhances troubleshooting and helps meet regulatory requirements
  • Robust web server provides remote visualization, access and control to reduce costly site visits
  • Built-in slot that accepts any Graphite I/O module, PID control module or communications module
  • Can be used with Graphite Expansion Racks to scale to 13 modules connected to the Edge and another 12 modules tethered via USB
