Product Overview

The Allen-Bradley 1794-OB16P functions as a high-density, distributed hardware component within the FLEX I/O platform. This digital DC output module provides 16 non-isolated, sourcing (PNP) channels to actuate 24V DC field loads. It eliminates traditional bulk wiring by mounting directly inside decentralized control enclosures near physical machinery. The module integrates electronic short-circuit and over-current protection to isolate field faults instantly, shielding up-stream system electronics from damage. This 100% brand new, factory-original module interfaces with industrial networks via standard FLEX I/O communication adapters, making it an essential control element for automated packaging lines, material handling equipment, and machine control networks.

Technical Specifications

Engineering Advantages

• Streamline High-Density Control Panels: The compact 94 x 94 mm footprint packs 16 separate sourcing channels into a minimal spatial profile. This density reduces overall enclosure size requirements and frees up critical DIN-rail real estate.

• Stop Fault Propagation Automatically: Built-in electronic fusing detects short circuits and over-current anomalies on individual field lines. The module cuts power to the affected channel immediately, triggers a diagnostics LED, and keeps the remaining 15 channels running without system-wide trips.

• Execute Hot-Swap Maintenance safely: The two-piece modular design separates the 1794-OB16P execution module from the terminal base block. Technicians slide the module out for service under full system power without disconnecting field wiring or disrupting network communications.

• Simplify Complex Signal Routing: The module terminates directly onto 1794-TB3 or 1794-TB3S bases, which provide internal power rail distribution. This configuration eliminates external terminal strips, stripping out hundreds of feet of jumper wires from the control panel blueprint.

• Withstand Extreme Floor Vibration: Heavy-duty construction details allow the module to absorb up to 5G of continuous vibrational force. This mechanical resilience ensures zero signal dropout when mounted directly on heavy stamping presses, material handling conveyors, or high-speed packaging machinery.

FAQs

• Which specific terminal blocks work best with the 1794-OB16P module?

  The 1794-OB16P mounts securely onto several FLEX I/O bases, including the 1794-TB2, 1794-TB3, 1794-TB3S, and 1794-TBK. For standard 24V DC sourcing applications, the 1794-TB3 and 1794-TB3S terminal blocks provide the most efficient wiring path because they contain the extra common and power terminals required for 3-wire field devices.

• Does the electronic protection require manual resetting after a short circuit occurs?

  No. The electronic protection automatically resets once you remove the physical short-circuit or over-current condition from the field wiring. This autonomous recovery minimizes manual technician intervention and shortens machine downtime.

• How do I verify the authenticity and condition of this product?

  We supply this specific model as a 100% brand new, original factory-sealed unit inside its native Allen-Bradley industrial packaging. The unit retains its factory barcode sticker, serial number tracking, and sealed internal static bag, ensuring it has never seen service on a factory floor.
