Turck's JBBS junction bricks for AS-interface networks are approved for hazardous locations
Turck's JBBS junction bricks for AS-interface networks are FM approved for Class I, Division 2, Groups A, B, C and D hazardous locations. JBBS junction bricks are designed to simplify the connection of multiple field devices and can be mounted directly on the machine in hazardous environments with no enclosure required.
The bricks include options with four, six or eight short-circuit protected ports that can be shut off via integrated dip switches located under the cover of the station. This design allows users to service the device while maintaining normal operating conditions in the hazardous area. The IP69K-rated JBBS junction bricks are available with M12 or 7/8-16UN connectors in stainless steel or nickel-plated brass.
