1769-OB16P | Allen Bradley CompactLogix 16-Point Protected DC Output Module

Product Overview

The Allen Bradley 1769-OB16P operates as a high-density digital output module within the CompactLogix ecosystem. It provides 16 solid-state 24V DC outputs to drive solenoids, contactors, and indicators. This module distinguishes itself through Integrated Electronic Protection, which shields the hardware from overcurrent and short-circuit conditions. We supply this unit as 100% Brand New and Original, providing a mission-critical interface for modern industrial control architectures.

Technical Specifications

The 1769-OB16P delivers robust performance via the following technical parameters:

Engineering Advantages

• Integrated Fault Mitigation: The "P" suffix denotes advanced electronic protection. This feature detects short circuits and thermal overloads at the individual output level, preventing localized faults from damaging the entire module or the CompactLogix backplane.

• Superior Thermal Management: The hardware design optimizes heat dissipation. By allowing up to 8.0 Amps of total current at 30 °C, the module supports heavy-duty inductive loads without requiring external cooling fans.

• High-Speed Switching: With signal delays as low as 1 ms, this module fits high-speed sorting and packaging applications where precise timing determines throughput efficiency.

• Efficient Rack Density: The 16-point single-group configuration minimizes cabinet space. Engineers can drive multiple field devices while occupying only one slot on the 1769 bus, streamlining the overall control footprint.

FAQs

• What does the "P" in 1769-OB16P signify?

  The "P" stands for Protected. Unlike standard OB16 modules, the 1769-OB16P features built-in electronic short-circuit protection, eliminating the need for external fusing for each output point.

• Can I mix this module with other 1769 modules on the same rack?

  Yes. The 1769-OB16P communicates over the standard Compact I/O bus. Note the 8-module distance rating; you must place the module within 8 slots of the system power supply to ensure stable voltage levels.

• Does this module support "Sinking" or "Sourcing" wiring?

  The 1769-OB16P is a Sourcing module. It provides 24V DC power to the field device, which then connects to the common return (negative) line.

• What happens if an output short-circuits?

  The integrated protection circuit immediately trips the affected channel to prevent hardware failure. Once you clear the fault and reset the output in the controller software, the module resumes normal operation.
