Moore Industries SPA2IS programmable alarm trip with IS field connections

Moore Industries has announced its SPA²IS programmable alarm trips with built-in intrinsically safe (IS) field connections. Now users in the chemical, pharmaceutical, petrochemical, oil and gas extraction and refining industries that monitor, control and measure signals in hazardous areas have an alarm solution that significantly reduces wiring, installation and maintenance costs. The SPA²IS is a combination alarm trip and temperature transmitter solution that includes built-in intrinsically safe field connections for current/voltage, RTDs and thermocouples.

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 can be costly and instrumentation often requires the additional purchase of a separate Zener or isolating barriers and power supply.

For facilities that employ intrinsic safety measures the SPA²IS is a cost-effective 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 SPA²IS 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 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. 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.
