This adapter serves as a communication interface node, enabling the connection of up to two local FLEX I\/O modules to a master programmable controller via the Allen-Bradley RIO network. It is specifically optimized for low-density, distributed automation tasks, such as remote valve control, operator interface stations, and compact machinery sub-panels.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Architecture:\u003c\/strong\u003e Supports a 2-slot configuration, providing a space-efficient solution for small-scale I\/O requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetwork Compatibility:\u003c\/strong\u003e Utilizes standard Allen-Bradley Blue Hose coaxial media for reliable communication on RIO networks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Baud Rates:\u003c\/strong\u003e Supports communication speeds of 57.6 Kbps, 115.2 Kbps, and 230.4 Kbps to match existing system requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Power Management:\u003c\/strong\u003e Converts 24 VDC input to a regulated 5 VDC backplane supply, providing up to 640 mA for attached modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Hardening:\u003c\/strong\u003e Engineered with high immunity to Electrical Fast Transients (EFT) and surges up to 2 kV, along with 8 kV ESD protection and 10 V\/m RF field immunity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe 1794-ASB2 is ideal for decentralized plant floor applications where limited I\/O points are required at a specific location.
