1734-OB8K | Allen Bradley | POINT I/O 8-Point Sourcing 24V DC Digital Output Module

Product Overview

The Allen Bradley 1734-OB8K functions as a high-density digital output interface within the POINT I/O system. This module switches 24V DC sourcing signals to drive field devices such as solenoids, contactors, and actuators. Featuring a conformal coating, the 1734-OB8K provides enhanced protection for internal circuitry against harsh industrial atmospheres. We supply this unit as 100% Brand New original factory equipment, ensuring maximum uptime for your distributed control architecture.

Technical Specifications

Engineering Advantages

• Superior Corrosion Resistance: The conformal coating shields the 1734-OB8K from moisture, salt spray, and airborne chemical contaminants. This hardware-level protection prevents short circuits and trace degradation in aggressive environments like pulp and paper mills or marine applications.

• Space-Efficient Design: The ultra-slim POINT I/O profile occupies minimal horizontal space on the DIN rail. This allows engineers to deploy localized I/O at the point of control, significantly reducing the amount of field wiring returning to the main control panel.

• Integrated Diagnostics: Local status indicators on the front panel provide real-time feedback for module health and individual output status. Technicians identify faults immediately without opening software, accelerating the troubleshooting process on the factory floor.

• Modular Flexibility: The 1734-OB8K snaps onto a standard terminal base (1734-TB or 1734-TBS). This modularity allows for the "Removal and Insertion Under Power" (RIUP) of the module, enabling system maintenance without disrupting the power to the rest of the I/O bank.

FAQs

• What does the "K" suffix represent in the 1734-OB8K part number?

  The "K" designates that the module features a factory-applied conformal coating. While it remains electrically identical to the standard 1734-OB8, the coating adds a layer of chemical and moisture protection for hazardous or corrosive industrial settings.

• Does this module include the terminal base for wiring?

  No. The 1734-OB8K is the plug-in module only. You must install it into a 1734-TB, 1734-TBS, or 1734-TOP terminal base. Ensure the mechanical keying on the base matches the module requirements before insertion.

• Can the 1734-OB8K drive 24V DC solenoids directly?

  Yes. The sourcing outputs provide up to 1.0A per point, which handles most standard industrial solenoids and relay coils. Always verify that the total module current draw does not exceed the 3.0A limit across all 8 points simultaneously.

• Is this product an original factory-sealed unit?

  Yes. We guarantee that every 1734-OB8K we ship is 100% Brand New in the original manufacturer’s packaging. We do not sell used, refurbished, or open-box surplus items.
