The SPA2IS is a combination alarm trip and temperature transmitter solution that includes built-in intrinsically safe (IS) field connections for current/voltage, resistance temperature detectors (RTDs) and thermocouple. It is powered by a universal ac/dc power supply and provides on/off control, warns of unwanted process conditions, alarms on rate of change and assists with or performs emergency shutdowns. It accepts a variety of signal inputs from transmitters and temperature sensors and provides dual and quad independent and individually configurable alarm relay outputs when a monitored process variable falls outside of user-set high or low limits.
