Wireless Cellular Alarm Monitoring

TThe S2C is a DIN-mountable SCADA-to-cloud interface designed for industrial environments requiring reliable remote monitoring, cellular failover, and real-time alarm notifications. Whether you're managing tanks, pumps, or distributed assets, the S2C bridges legacy systems with modern cloud infrastructure—without the need for on-site servers or complex VPN setups.

Key Features

  • 4x 4–20mA Analog Inputs for sensors and transmitters
  • 12x 120Vac or 24Vdc Alarm Inputs with opto-isolated channels
  • Cellular Connectivity (LTE-M / 4G) with tamper-proof antenna
  • Built-in VPN & Bluetooth for secure configuration and diagnostics
  • Relay Output for remote control or cellular signal falure alarm
  • Temperature Range: –40°C to +85°C for harsh environments
  • DIN Rail Mounting for easy integration into control panels

Benefits

  • Plug-and-play cloud integration —no IT overhead
  • Real-time alerts via email, SMS, Voice or dashboard
  • Cellular failover ensures uptime even during network outages
  • Compact footprint ideal for retrofit and new installations
  • Designed for engineers —no scripting or custom firmware required
