Product Description
The 1794-ADN is a Flex I/O DeviceNet adapter used to interface a FLEX I/O rack with a DeviceNet scanner for cyclic I/O data exchange. Designed for 24 VDC systems, it offers selectable network baud rates and provides status indication for module/network and I/O. The unit supports DIN rail or panel mounting and is intended for open-style, in-cabinet installations. Typical wiring uses 12 AWG stranded conductors with up to 1.2 mm insulation, and Belden YR-29832 or equivalent DeviceNet cabling. Operational limits include 0 to 55 °C ambient, with vibration and shock ratings per IEC 68-2-6. Electrical specifications include 19.2–31.2 VDC input range, up to 7.6 W dissipation at 19.2 VDC, 50 V continuous isolation, and a 640 mA max 5 V FlexBus output. Indicators provide quick diagnostics, and IP20 construction aligns with control cabinet use. The adapter is suitable for applications requiring reliable DeviceNet connectivity within Rockwell FLEX I/O architectures.
