Gateway with fail-safe PLC is a specialized product category rather than a specific brand, often associated with industrial automation solutions. These products are typically offered by leading PLC manufacturers such as Siemens (Germany), Rockwell Automation (USA), or Schneider Electric (France). They serve critical industries like manufacturing, energy, and process control by providing reliable communication gateways integrated with fail-safe programmable logic controllers (PLCs) for mission-critical applications. The main products include industrial-grade gateways with SIL3/PLd safety-rated PLCs, designed to ensure uninterrupted operation and safe shutdown in hazardous environments. These solutions are commonly found on industrial supply platforms like Radwell and Grainger.
