Product Description

The 1794-ACN is a ControlNet adapter module for Allen‑Bradley FLEX I/O 1794 systems, providing a high‑reliability interface between distributed I/O modules and ControlNet networks. Operating from a 24 VDC supply with a wide 19.2–31.2 VDC input range, the adapter supports up to eight FLEX I/O modules on the local FlexBus. It delivers up to 640 mA at 5 VDC to the FlexBus and is designed with 850 VDC isolation for robust industrial environments. Typical power consumption from the external 24 V supply is 400 mA, with a maximum dissipation of 4.6 W at 19.2 VDC. Communication over ControlNet is supported at 5 Mbit/s and uses Belden RG‑6/U coaxial cabling. This unit is suited for deterministic, time‑synchronized control applications requiring modular, distributed I/O, and integrates seamlessly within the FLEX I/O 1794 product family. Package weight is approximately 0.44 lb (0.20 kg).
