Programmable alarm trips WITH IS FIELD CONNECTIONS


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.


 Key features of the SPA2 IS include:


• Intrinsically-safe field connections - Apply inputs from temperature sensors or transmitters located in hazardous areas without the need of a costly intrinsically-safe barrier. Plus power an intrinsically-safe loop using the 2-wire transmitter excitation in the current/voltage input model. • Universal plant standard - With


programmable input/output parameters and universal DC or AC power input, there’s no need to stock dozens of different alarm trips. • 20-bit input resolution - Delivers

IS


programmable alarm trips with built-in intrinsically-safe (IS) field connections. Now process engineers in the chemical, petrochemical, oil & gas extraction & refining and pharmaceutical industries that monitor, control, and measure signals in hazardous areas have an alarm solution that significantly reduces wiring, installation and maintenance costs. The SPA2


trip and temperature transmitter solution that includes built-in intrinsically-safe field connections for current/voltage, resistance temperature detectors (RTDs), and thermocouples. The IS approach, as a method of hazardous area protection with monitoring and measurement instruments, is increasing globally. Many industrial sites that have previously implemented explosion- proof or flameproof protection are now utilising a hybrid approach of both protection methods in their hazardous

areas. Constructing or retrofitting IS solutions within these plants can be costly and instrumentation often requires the additional purchase of a separate zener or isolating barrier and power supply.


 For facilities that employ intrinsic safety measures the SPA2


IS is a cost-effective IS is a combination alarm


and complete alarm solution that includes intrinsically-safe field connections, which provides the necessary protection typically afforded by a galvanically isolated intrinsically safe barrier. In addition, the SPA2


IS cuts wiring and


maintenance costs by enabling users to eliminate additional barriers and power supplies, which reduces space requirements and heat dissipation or cooling considerations in barrier marshalling cabinets. The SPA2


IS is powered by a universal


AC/DC power supply and provides on/off control, warns of unwanted process


industry-best digital accuracy for both sensor (RTD and thermocouple) and analogue (current/voltage) inputs. • Site- and PC-programmable - Featuring security password protection, the SPA2


IS offers the choice of using


front panel pushbuttons or our FREE Windows-based Intelligent PC Configuration Software for fast and simple set up. • Large 5-digit process and status


readout - A large backlit display shows menu prompts during pushbutton configuration and, when the SPA2


operation, shows the process variable, the output, or toggles between the two in selectable engineering units. • Combined alarm trip and


transmitter - The analogue output (-AO) option reduces costs and installation time when both alarm and transmitter functions are needed at the same location. • Long-term stability - Provides up to


five years between scheduled calibrations. • Isolated and RFI/EMI protection -


Delivers superior protection against the effects of ground loops and plant noise.
