Allen-Bradley 1794-OB16P Digital Output Module – FLEX I/O Series
When a digital output module fails on the production floor, the consequences are immediate and severe: actuators freeze, conveyor lines halt, robotic arms lock in place, and safety interlocks may trip the entire cell. Every minute of unplanned downtime in a discrete manufacturing environment can cost thousands of dollars in lost throughput. The Allen-Bradley 1794-OB16P is the precision component that stands between your process and that scenario — a field-proven, 16-point sourcing digital output module engineered for the demands of continuous industrial operation.
Within the Allen-Bradley FLEX I/O platform — Rockwell Automation’s modular, DIN-rail-mounted I/O architecture designed for distributed control — the 1794-OB16P occupies a critical role as the standard 24 VDC sourcing output module. Its 16 individually protected output points, compact form factor, and compatibility with the full range of 1794 adapter modules make it one of the most widely deployed output modules in North American and global discrete manufacturing. From automotive body shops to food and beverage packaging lines, the 1794-OB16P is a cornerstone of Allen-Bradley FLEX I/O installations worldwide.

Frequently Asked Questions
Q: What is the difference between the 1794-OB16P and the 1794-OB16?
A: The 1794-OB16P includes individual electronic short-circuit protection (“P” suffix = Protected) on each of its 16 output points. The 1794-OB16 does not include per-point protection. For most modern installations, the 1794-OB16P is the preferred choice due to its enhanced diagnostic and protection capabilities.
Q: Is the 1794-OB16P compatible with ControlLogix and CompactLogix controllers?
A: Yes. When paired with an appropriate FLEX I/O adapter (e.g., 1794-AENT for EtherNet/IP), the 1794-OB16P is fully compatible with ControlLogix (1756) and CompactLogix (1769) controller families via Rockwell Studio 5000 Logix Designer.
Q: Can the 1794-OB16P be replaced while the system is powered (hot-swap)?
A: Hot-swap capability depends on the adapter module configuration and system design. Consult the 1794-OB16P installation instructions (Rockwell publication 1794-IN006) and your adapter’s user manual before attempting live replacement.
Q: What terminal base is required for the 1794-OB16P?
A: The 1794-OB16P requires a compatible 1794 terminal base. Common options include the 1794-TB3, 1794-TB3S, and 1794-TB32. Terminal base selection depends on your wiring method (screw terminal vs. spring clamp) and field wiring requirements.
Q: Do you supply new or surplus units?
A: We supply both new (factory-sealed) and tested surplus units depending on availability. All units are clearly identified by condition in our quotation. Contact us to specify your preference.
Q: What is the lead time for the 1794-OB16P?
A: Lead time varies by current stock levels and sourcing channel. Submit an RFQ and we will confirm availability and lead time within 1 business day.
