Moore's new SPA2IS programmable alarm trips include built-in intrinsically-safe (IS) field connections. It’s a combination alarm trip and temperature transmitter solution that includes built-in intrinsically-safe field connections for current/voltage, resistance temperature detectors (RTDs), and thermocouples. The SPA2IS 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. Very versatile, it accepts a wide 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 and/or low limits.
