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.
The DART components of the FieldConnex® range are now in stock. Fieldbus installation is safe, available, and powerful as never before – with full intrinsic safety. DART Fieldbus provides what many users have been asking for: The intrinsically safe High-Power Trunk concept. DART Fieldbus overcomes the power limitations of FISCO or Entity fieldbus systems and enables at the same time:
DART Fieldbus comes with ATEX and IEC Ex certification and is therefore ready for practical application.
The DART Power Hub is based on the popular FieldConnex® High-density Power Hub. It provides power to the segment and connections to the DCS system. It detects and switches off the spark.
The DART Segment Protector provides intrinsically safe outputs Ex ib. Any intrinsically safe instrument can be connected.
