Part of the Moore Industries FS FUNCTIONAL SAFETY SERIES, the exida® SIL 2 and SIL 3 certified STA Safety Trip Alarm performs as a logic solver and acts on potentially hazardous process conditions; warns of unwanted process conditions; provides emergency shutdown; or provides on/off control in Safety Instrumented Systems (SIS) and traditional alarm trip applications.

The 4-wire (line/mains-powered) STA models accept a signal input from transmitters, temperature sensors and a wide array of other monitoring and control instruments including:

  • Current and Voltage Signals
  • Temperature (RTD and T/C) Sensor Inputs
  • Resistance and Potentiometer Devices
  • Direct Millivolt Sources
