- FLEX I/O ControlNet adapter with one nonredundant BNC network channel
- Supports up to eight FLEX I/O modules and communicates at 5 Mbps
- 19.2–31.2 V DC input with 5 V DC, 640 mA FLEXBus output
1794-ACN15 is the Allen-Bradley ControlNet adapter for a FLEX I/O node.
The adapter couples the ControlNet network to the local FLEXBus, provides node-address switches and status indicators, and supplies the documented 5 V DC bus output for attached modules.
Before replacement, record the node address and network schedule, then verify the BNC tap, termination, input power, FLEXBus keying, mounting base, module count, wiring, and controller configuration.
Availability, condition, price, and shipping time for 1794-ACN15 are confirmed during quotation.
