Seamless data collection and control that’s easy to deploy and manage

Samsara Industrial Gateway (IG) is a programmable logic controller or PLC that provides data collection and control of industrial operations. With built-in connectivity, I/O, data storage, and processing, the IG can be deployed in less time than traditional PLCs and is securely managed through the cloud.

Simplified SCADA architecture

Samsara IGs combine the functionality of a PLC and a gateway, built with preprovisioned cellular, so that you can control operations and collect data without worrying about additional connectivity equipment. The PLC connects directly to cloud-based SCADA software for management, control programming, dashboards, alerts, and reporting.

Instead of having to call an operator, I did everything I needed to do from my cell phone–controlling the pumps, turning them on and off, and looking at the pressures. Our old system couldn’t do that.

Local program execution

Programs are executed and stored locally so that data collection and operation continues even if cloud connection is lost.

Scalable for growing operations

Samsara IGs are easily deployed alongside instrumentation, sensors, existing controllers, or as a stand-alone PLC. I/O and device drivers for the most common industrial protocols enable you to easily connect existing equipment and expand as your operations grow.
