Moore Industries has released the new SPA2IS programmable alarm trips with built-in intrinsically-safe (IS) field connections. Now customers 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 newest member of Moore Industries' family of Limit Alarm Trips and Switches, the SPA2IS is a combination alarm trip and temperature transmitter solution that includes built-in intrinsically-safe field connections for current/voltage, resistance temperature detectors (RTDs), and thermocouple.
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 utilizing 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 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.
