MSA SENTRY io Fixed Gas Controller

The SENTRY io Controller provides an easy-to-use platform for nearly any application and skill level.

Modern touchscreen HMI supports intuitive setup, operation, and troubleshooting workflows.

Guided setup and auto-recognition of MSA and General Monitors flame and gas detectors through HART saves valuable time during setup and configuration.

Flexible Platform

  • Multiple communication interfaces: Modbus TCP/IP, Ethernet/IP, optional Modbus RTU.
  • Robust logic control features, such as cause-and-effect and voting schemes.

Easy to Use

  • SmartStart guided setup walks users through the setup process during commissioning, saving valuable programming time.
  • EZ-ID auto-recognition for a robust library of HART-enabled MSA and General Monitors detectors for easy setup.

Scalable Platform

  • Equipped with Device Level Ring (DLR) networking options that deliver financial and schedule savings in projects.
  • Saves wiring expenses and complexity with a loop topology to connect multiple controllers in a single run.
  • Ability to network Sentry io together with other units offers significant cost savings on new and old installations.
