Allen-Bradley 1783-SAD4T0SBK9A Industrial Ethernet Switch

Allen-Bradley 1783-SAD4T0SBK9A is a Stratix 5950 Industrial EtherNet/IP Security Appliance that adds robust network security to 4-port copper Ethernet deployments on EtherNet/IP systems. It provides four 10/100/1000 Base-T ports for wired connections and uses K9 encryption to protect data in motion, with limited VPN capabilities for remote access when configured. The unit is designed as a dedicated security appliance within Rockwell Automation's Stratix family, suitable for safeguarding plant-floor networks and control-system communications. Power is supplied from 12 to 48 V DC and typical current draw up to 2.0 A; an alarm relay is supported (30 V DC, 1 A or 48 V DC, 0.5 A) for system fault signaling. Certifications include CE and RoHS, and certain hardware revisions carry hazardous-location approvals (e.g., Ex nA nC IIC T4 Gc) per the technical data for 1783-SAD4T0SBK9 variants. This makes it appropriate for industrial environments where securing EtherNet/IP traffic and controlling remote access are priorities.
