Moore Industries STA

The STA Safety Trip Alarm is part of the Moore Industries FS FUNCTIONAL SAFETY SERIES and is certified to Exida, SIL 2 and SIL 3. It 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


The STA monitors a temperature, pressure, level, flow, position or status variable. If the input exceeds a user selectable
high or low limit, independent dual alarm outputs warn of unwanted process conditions, provide emergency shutdown or provide
on/off control.


The STA checks its own operation and configuration upon start up, and then continuously monitors its status during operation. It also continuously monitors its input signal. Our STA Alarm Trip (TPRG input model) performs continuous sensor diagnostics. This industry-first and patented Moore Industries feature saves you time and money by letting you know when a problem occurs,
and its type and location. If the RTD input breaks, the fault alarm is tripped. A plain-English error message on the display indicates exactly which RTD wire has broken. Specific error messages eliminate the work of removing the sensor or checking all lead wires to diagnose a problem.
