Allen-Bradley 1794-OV32
The 1794-OV32 is a 32-channel sinking digital output module for Allen-Bradley FLEX I/O systems. It operates at 24V DC (10–31.2V range), supports up to 14A total output current (grouped for channels 0–15 and 16–31), and features fast switching (0.5ms/1.0ms delays). Designed for industrial automation, it meets global safety standards (UL, CE, etc.) and is housed in a compact 94×94×89 mm enclosure.
