Product Overview

The Allen-Bradley 1769-OB16P functions as a high-density digital output solution within the Rockwell Automation Compact I/O family. This module provides 16 sourcing outputs, specifically designed to drive field devices such as solenoids, indicator lamps, and industrial relays. It integrates seamlessly with CompactLogix controllers, MicroLogix 1500 systems, and 1769-based distributed I/O clusters. We supply this unit in 100% Brand New original condition, complete with factory-sealed packaging to ensure maximum field reliability.

Technical Specifications

The 1769-OB16P delivers robust switching power with integrated electrical isolation to protect the system backplane.

Engineering Advantages

The 1769-OB16P addresses the requirements of high-demand machine control and packaging applications by offering superior current handling and diagnostic visibility.

• High-Current Sourcing Capability: Unlike standard low-power modules, the 1769-OB16P supports up to 1.0 Amp per point. This allows the module to drive larger solenoids and actuators directly without requiring interposing relays, saving significant cabinet space and wiring labor.

• Integrated Sourcing Logic: As a sourcing module, it supplies power from the 24V DC bus to the load. This standardizes wiring for NPN-style field devices and simplifies troubleshooting within a common-ground architecture.

• Galvanic Isolation Protection: The module features 750V DC isolation between the field-side wiring and the sensitive controller backplane. This barrier prevents electrical surges or field faults from damaging the expensive CPU or other I/O modules in the rack.

• Removable Terminal Block (RTB): The RTB design allows for "pre-wiring" of the control cabinet. During maintenance or replacement, you can disconnect the entire wiring bundle as a single unit, eliminating the risk of cross-wiring errors and reducing MTTR (Mean Time To Repair).

• Hazardous Location Certification: With Class I Div 2 approval, the 1769-OB16P operates safely in environments where volatile gases or vapors may exist, expanding its use into chemical processing and oil and gas applications.

FAQs

• Does the 1769-OB16P support Pulse Width Modulation (PWM)?

  No. The 1769-OB16P is a standard digital output module for ON/OFF control. For high-speed pulse or PWM requirements, you should utilize a specialty module like the 1769-HSC.

• What is the difference between this module and the 1769-OB16?

  The "P" in 1769-OB16P often denotes "Protected" or specific sourcing characteristics. While both offer 16 outputs, the 1769-OB16P typically provides higher current capacity (up to 1.0A per point vs. 0.5A on standard models), making it better suited for heavy inductive loads.

• How do I troubleshoot a specific output channel?

  The module features status LEDs for each of the 16 channels. If the controller logic activates an output but the corresponding LED remains off, check the module's 24V DC field power supply or the internal fuse status if applicable.

• Is this module compatible with the 1769-ADN DeviceNet adapter?

  Yes. The 1769-OB16P functions as a standard 1769 Compact I/O module and can be installed in a remote I/O rack managed by a 1769-ADN or 1769-AENTR adapter.
