Turck JBBS Junction Brick for AS-Interface Now FM Approved

TURCK announces that the company’s JBBS junction bricks for AS-interface® networks are now FM approved for Class I, Division 2, Groups A, B, C and D hazardous locations. JBBS junction bricks simplify the connection of multiple field devices and can be mounted directly on the machine in hazardous environments, with no enclosure required.


These bricks include options with 4, 6 or 8 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, minimizing downtime. This shut-off feature is the preferred method in order to minimize disruptions to the network.


The IP69K-rated JBBS junction bricks are available with M12 or 7/8-16UN connectors in stainless steel or nickel-plated brass.
