Allen-Bradley 1794-OA16 FLEX I/O 16-Point 120V AC Digital Output Module
Allen-Bradley 1794-OA16 is a FLEX I/O digital output module with 16 non-isolated 120 V AC triac outputs that switch line-voltage pilot loads directly from a FLEX I/O bank.
Overview
The 1794-OA16 provides sixteen 120 V AC outputs rated up to 4 A per module with 5 A inrush pilot duty. Outputs tolerate 74…132 V AC, drop at most 1.5 V AC at 0.5 A, and leak no more than 2.25 mA off-state. Each point has its own yellow indicator, and the module mounts on the full range of 1794 screw-clamp and spring-clamp terminal bases.
Key Features
- 16 non-isolated 120 V AC outputs (74…132 V AC window)
- 4.0 A output rating per module; 5 A inrush pilot duty
- 1.5 V AC maximum on-state voltage drop at 0.5 A
- Off-state leakage 2.25 mA maximum
- 16 yellow point-status indicators; keyswitch position 8
- Broad terminal-base compatibility (TBN/TB2/TB3 families)
- Open-style enclosure; DIN rail mount
