The ST-90 Quad Controller, with its wireless option, often functions as the "Site Controller" for the Rig Protector and other area monitoring applications when it is desirable to interface wirelessly with other controllers and alarm instrumentation.  For example, rig perimeter monitoring projects often require several Site Controllers to receive 4-20mA signals from sensors and annunciate strobes and horns for a local area. The ST-90 Quad's wireless interface makes it very easy to funnel its monitored data on to a larger controller for the entire rig. The ST-90 Quad four channel controller provides simultaneous display and alarm functions for four monitored variables. Easy to configure and user friendly, the ST-90 Quad functions as a critical alarm controller for toxic and combustible gases, vibration, tank levels and many other process values.
