Cell Switch™ technology was developed to enable industrial users to connect to their processes in real-time through existing cellular networks. with Cell Switch technology, as many as ten users can be connected to their processes in real-time with a standard cellular device.

The CS-440 is complete with four digital inputs and four digital outputs.

Each device is completely configurable to fit your demanding industrial applications.

  • Redundant Watchdog built for 24/7 operation
  • Assign up to 10 different mobile phone numbers
  • Password protected to prevent spoofing
Multi Alarm Logic
  • Accepts dry contact — if any input is triggered, a SMS is sent to authorized mobile phones
Multi Relay Drivable Outputs (12V-24V)
  • Any relay can be switched on by sending a SMS to the unit
