Pepperl+Fuchs (Twinsburg, OH) introduces the Dynamic Arc Recognition and Termination system (DART). According to the company, it is a power supply and control system for intrinsically safe fieldbus installations that increases the power available to field devices in explosion-hazardous areas. During normal operation, a DART power supply feeds full nominal power of 8 to 50 watts. Should a fault occur, the potential spark remains non-incendive, and DART detects the resulting change in current and immediately switches off the power supply. According to the company, energy from the electrical system is reduced to a safe level in microseconds.
