Product overview

The Allen-Bradley 1794-OA16 is a FLEX I/O digital output module with 16 nonisolated 120V AC outputs (85…132V AC), up to 4.0 A per module. It mounts on a 1794-TB3, 1794-TB2, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBN (with auxiliary terminal strips), 1794-TBKD or 1794-TBNK terminal base. 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.

Product descriptionFLEX I/O AC digital output module with 16 nonisolated outputs, 120 V AC nominal voltage and a 74…132 V AC output range.
Output voltage range74…132 V AC; 120 V AC nominal
Output current rating4 A per module (16 outputs at 0.25 A). If using 0.5 A outputs, alternate wiring so no two 0.5 A outputs are adjacent; total current must remain within the module rating.
