← Back to productsProduct overview
The Allen-Bradley 1794-OA8 is a FLEX I/O digital output module with 8 nonisolated 120V AC outputs (85…132V AC), up to 4.0 A per module. It mounts on a 1794-TBNF, 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBN, 1794-TBKD, 1794-TB3K, 1794-TB3SK or 1794-TBNK terminal base; the 1794-TBNF fused base is shipped with fuses for this module. FLEX I/O modules plug into a terminal base unit that carries the field wiring, so a module can be removed and inserted under power without disturbing field wiring; one FLEX I/O adapter communicates with up to eight I/O modules.
