Fieldbus at New Power Levels

Excitement around electrical explosion protection

FieldConnex DART Fieldbus

Intrinsic safety has been at the forefront of spark-prevention technology for decades. Proven in practice and simple to use, intrinsic safety is the most popular method of explosion protection. It is extremely safe and easy to apply. However, the low available direct power has limited its use in communication, instrument, and control technology. With DART Technology this is about to change.

Dynamic Arc Recognition and Termination reliably detects sparks developing anywhere within an electric circuit and cuts off the energy supply within only a few microseconds to prevent the spark from reaching an ignitable temperature. DART provides more power while maintaining the energy limits of intrinsic safety, opening new possibilities for plant operators. For its first application, which is fieldbus in hazardous areas DART Technology ends previous limitations for the number of devices and their power requirements.
